This is the selection criteria for recommended products on the Director Pi channel. Hello, this is Director Pi. Today's video is a yearly review of Vitamin C products.
Vitamin C effectively reduces skin pigmentation, helps fade acne scars, promotes collagen synthesis, and improves wrinkles and skin elasticity. So, how should you choose a Vitamin C product? Here's what to check.
First, pure Vitamin C (Ascorbic Acid) has strong antioxidant and brightening effects. However, it’s sensitive to sunlight, heat, and air, so it’s best to use it within 3 months. Ethyl Ascorbic Acid has both water- and oil-soluble properties, making it well-absorbed by the skin. Ascorbyl Glucoside is a combination of Ascorbic Acid and glucose. At 2% concentration, it is effective as a brightening agent. Ascorbyl Tetraisopalmitate penetrates deeper into the skin. Magnesium Ascorbyl Phosphate is a water-soluble form of Vitamin C, while Ascorbyl Palmitate and Tetrahexyldecyl Ascorbate are oil-soluble, with the latter being particularly notable for its strong antioxidant properties and better absorption.
In addition to these Vitamin C derivatives, Tranexamic Acid is another widely used ingredient. It suppresses melanin production, making it suitable for acne-prone and sensitive skin. There are also antioxidants that enhance the effectiveness of Vitamin C. Ferulic Acid increases the efficacy of Vitamin C and E, creating a synergistic effect. Tocopherol (Vitamin E) has high antioxidant properties, helping to extend the longevity of the product’s effects. Glutathione is effective at reducing oxidative stress on the skin, while Bisabolol, an extract from chamomile, not only provides antioxidant benefits but also has anti-inflammatory effects.
If your skin is highly sensitive, I recommend choosing products with Vitamin C derivatives or Niacinamide. These are less likely to cause irritation, as they work at a slightly acidic to neutral pH, minimizing stinging or burning sensations. On the other hand, if your skin is less sensitive, like mine, and you want stronger results, using high-concentration pure Vitamin C would be ideal.
Now, let’s dive into the reviews of products based on their ingredients. The first product features Niacinamide as the main ingredient. If Niacinamide is present at concentrations above 3%, it is considered high. However, for sensitive skin, it may cause irritation around the edges of the skin or near the eyes, so be cautious when using it.
The first product is GREEN TANGERINE VITA-C Dark Spot Care Serum by Goodal. This product combines 4% Niacinamide with Arbutin for brightening efficacy. It also includes tangerine extract, Ascorbyl Glucoside, and Tocopherol to deliver antioxidant benefits. The slightly yellow tint of the serum is designed to match its concept. Unlike typical Vitamin C products that often feel greasy and unpleasant, this one has a nice texture, according to user reviews. Goodal’s product focuses on brightening with Niacinamide and offers a pleasant application similar to general brightening ampoules. It has 4% high-concentration Niacinamide and is effective for brightening and wrinkle improvement. This serum is suitable for combination and dehydrated-oily skin types, but those with seborrheic dermatitis, atopic, or sensitive skin should use it with caution.
The next product is RTX INTO SERUM Vitaminshot by Dr.G. It contains 5% Niacinamide, Spicule soothing ingredients, Ascorbic Acid, and Tocopherol. One of the key ingredients, hydrolyzed sponge (Spicule), helps deliver active ingredients into the skin. To apply, gently rub it in and press lightly for better absorption. The texture is light and easy to spread, but some users with sensitive dehydrated-oily skin reported that it stings and feels irritating. One user mentioned that after a few days of use, their skin felt irritated rather than improved. This product contains 5% Niacinamide and Spicule, but only a minimal amount of Vitamin C. A rich moisturizing cream is recommended after use. Those with seborrheic or sensitive skin should be cautious.
The third product is Blemi Shot Ampoule by AMPLE:N. It contains 5% Niacinamide and a small amount of Vitamin C derivatives. Unlike other products, it uses Hexylresorcinol to boost its brightening effects. This ampoule also includes ingredients for exfoliation and sebum control, so it is better to use it every 2–3 days instead of daily. Some users with dehydrated-oily skin reported slight itchiness. When I tried it, I didn’t notice much improvement in dark spots or blemishes. This product features high-concentration Niacinamide at 5% and is designed for brightening and wrinkle care. Using it 2–3 times a week is ideal.
The next product is Vitamin C Brightening Serum by MEDIHEAL. This serum contains about 3% Niacinamide, along with small amounts of Vitamin C derivatives and pure Vitamin C. Some reviews mentioned a sticky finish, which is due to the inclusion of Betaine. However, users also noted that their skin felt hydrated until the morning after application. While it provides good hydration and a slightly brightened complexion, I didn’t notice significant fading of dark spots or blemishes. This serum contains 3% Niacinamide at a medium concentration, offering brightening and wrinkle care benefits. It provides an instant brightening effect upon application, making it suitable for combination and dehydrated-oily skin types. Individuals with seborrheic, atopic, or sensitive skin should exercise caution when using this product.
VITA NIACINAMIDE DARK SPOT SERUM by Round Lab. This serum contains 5% Niacinamide, along with Vitamin Tree Water and Tranexamic Acid as brightening boosters. Tranexamic Acid prevents melanin pigments from settling deeply on the skin. The serum absorbs quickly and provides a moderately hydrating feel. Users reported improvements in skin tone uniformity and smoothness. With 5% high-concentration Niacinamide, this product offers brightening and wrinkle care benefits. Thanks to its soothing ingredients, it is low-irritation and offers a good balance of oil and moisture, making it suitable for oily and dehydrated-oily skin types.
Next is Glutathiosome Dark Spot Serum Vita Drop by Abib. This product features 5% Niacinamide for high-concentration brightening and exfoliation. It also includes "Plusome" (5%), which combines water-based moisturizers, barrier-supporting ingredients like cholesterol, and antioxidants as its main functions. The capsules in the serum dissolve easily when rubbed, and they are not overly noticeable. However, applying multiple layers may cause some pilling, so it's best to spread a thin layer. After long-term use, users reported slight fading of dark spots. With its high-concentration 5% Niacinamide, brightening, and wrinkle-improving functions, the serum is hydrating and ideal for oily skin.
This product primarily features vitamin C derivatives as its key ingredient. The next product is TONING C Dark Spot Serum by Cell Fusion C. This serum uses Ethyl Ascorbic Acid as a Vitamin C derivative. It has a sticky, mucus-like texture and requires patting after application to enhance absorption. While it provides good initial hydration, follow-up moisturizing products are necessary to maintain moisture. Users noticed improved skin texture and a slightly brighter complexion but didn’t see significant improvements in dark spots or blemishes. This product focuses on brightening and wrinkle care with Vitamin C derivatives. It is not highly hydrating but pairs well with makeup.
The next product is GLOW VITA C TONING SERUM ORANGE & NEROLI. This serum uses medium-concentration Vitamin C derivatives combined with oil, providing a dewy, glowing finish. It feels similar to applying a thin oil serum. The hydration level is moderately high, but it may feel heavy for oily skin. With a pH of 5.20, the product leaves the skin soft and smooth but doesn’t significantly improve dark spots or blemishes. It contains 2% Vitamin C derivatives and a small amount of Bakuchiol for brightening and wrinkle care. Its balanced oil and moisture content is suitable for dry skin.
The next product is CELLMAZING Vita C Brightening Ampoule by Torriden. This product contains medium-concentration Vitamin C derivatives, approximately 2% Ethyl Ascorbic Acid, with antioxidant, soothing, and brightening properties. It also includes 2% Niacinamide and is designed to be low-irritation. The serum has a milky color and a light, watery texture. While it initially feels hydrating, it quickly dries down and provides very little oil. This product contains 2% Vitamin C derivatives, offering brightening, wrinkle care, and pore-moisturizing benefits. It has a lightweight formula; it may cause dryness.
The next product is Poncirus Trifoliata C Dark Spot Serum by make p:rem. This serum features low-concentration Vitamin C derivatives and antioxidant ingredients. Although it starts off feeling slightly oily, it absorbs well, leaving a smooth texture. The product is formulated for brightening and wrinkle care with Vitamin C derivatives and antioxidants. It feels similar to a hydrating, non-sticky ampoule and is suitable for sensitive skin.
DERMA+ ANSWER MELA SPOT BRIGHTENING AMPOULE by CNP. This ampoule combines 3% Sodium Ascorbyl Phosphate, 2% Ascorbyl Glucoside, and Ascorbyl Palmitate for a total Vitamin C derivative concentration of over 5%. It also contains Ferulic Acid, which enhances the effectiveness of Vitamin C and E, as well as Sodium Lactate, which provides mild exfoliation without irritation. The serum spreads smoothly and feels slightly oily but also hydrating. For dry skin, it maintains moisture without feeling overly greasy. Users reported slight improvements in dark spots and smoother skin texture after use. With over 5% Vitamin C derivatives, this product offers effective brightening, wrinkle care, and a well-balanced oil and moisture formula. For dry skin types, this product is recommended.
A low to medium concentration of pure vitamin C. There are many acidic products. It’s essential to choose products that incorporate antioxidants effectively. To prevent oxidation, it’s best to use them within two months after opening.
The first product I’ll review is Super Drops-Vita C Toning Serum by Belif. This serum uses a low concentration of pure vitamin C for brightening and includes Niacinamide for additional skin benefits. It also provides hydration and calming effects. Upon application, it is instantly absorbed into the skin. However, one review from someone with dehydrated-oily skin mentioned that the product caused rough skin texture and breakouts, making it feel less cleansing than expected. While it has a good absorption rate and a pleasant texture, individuals with sensitive skin should be cautious.
Next, we have Angel Aqua Vita C 7% Brightening Ampoule by Beyond. This product uses 5.2% Ascorbic Acid and 1.8% Ethyl Ascorbyl Ether to enhance its brightening properties. For hydration and soothing, it contains 2.7% Panthenol. The formula has a medium strength of vitamin C derivatives and offers both brightening and wrinkle care benefits. It absorbs smoothly without being sticky, providing a comfortable and hydrating feel. This product has a 7% medium-strength vitamin C derivative, offering brightening and wrinkle care benefits. The application is easy, and the overall experience is quite pleasant, making it a well-received product.
Youth Radiance Vitaminol Serum by Primera. This serum contains high concentrations of oils and powders with a low concentration of pure vitamin C and its derivatives. It also includes Retinol (500 IU) for firmness. The product immediately makes the skin appear smooth and radiant due to the powder and titanium dioxide pigments, which provide instant brightness. Shake the bottle well before use to ensure proper mixing, as uneven application can affect the results. After using it for about two weeks, I noticed similar effects to other pure vitamin C products. It contains low-strength vitamin A and vitamin C with wrinkle care properties. However, since it tends to discolor after about a month, it’s best to use it within 1 to 2 months after opening.
Now, let’s move on to high-strength pure vitamin C products. These contain more than 15% ascorbic acid. It's crucial to use these within 1 to 2 months after opening, as they can change color. Sensitive skin users should be cautious.
Green Tangerine VITA-C 27 Dark Spot Care Ampoule by Goodal. This product contains 27% ascorbic acid, tangerine extract, and antioxidants from vitamin A and C. The ascorbyl ethyl ether used here is a more easily absorbed vitamin C derivative. However, the texture feels somewhat sticky, and the moisture level isn’t very high. Even after applying cream, my skin still felt dry. Some users with sensitive skin reported intense stinging, redness, and irritation. This high-strength product (27% pure vitamin C) is great for brightening and wrinkle care, but its high acid content, including AHA, makes it quite potent. It’s advisable to adjust the usage frequency.
Gluta Vitamin C Toning Ampoule by IOPE. With 25% ascorbic acid, this product combines vitamin C derivatives, including ethyl ascorbic acid, with oil for better absorption. The use of propanediol and water makes the texture smoother compared to other products. It helps exfoliate and refine the skin, providing a smoother texture and a slight brightening effect on the skin tone. This high-strength vitamin C (25%) and vitamin C derivatives work well for toning and improving skin texture, especially for aging skin concerns. However, it is not suitable for sensitive or atopic skin.
Vitamin C 15 Serum by Cos De Baha. This product contains 15% pure vitamin C and 2% arbutin. Arbutin helps prevent melanin spread under sun exposure. It has a similar feel to other high-strength vitamin C products. When first applied, there is a noticeable stinging sensation. The pH is slightly acidic, and after using it for a while, my skin tone became more even. It can be used alone, but it's recommended to mix it with cream and apply it to areas with pigmentation for better results. Although the product says it’s good for 6 months after opening, oxidation happens quickly, so it's best to use it within 2 months, and at most 3 months.
This contains 19% pure vitamin C with a high concentration for brightening and wrinkle care, but the texture isn’t the best. It's more suited for oily and combination skin, but those with seborrheic or sensitive skin should be cautious.
Let’s pick the top Vitamin C products of the year. Before we begin, let's learn how to effectively use Vitamin C. If you're using Vitamin C derivatives, apply them like a regular ampoule. It’s also a good idea to apply sunscreen.
When using pure Vitamin C, apply in the order of low, medium, and high concentrations. Using it 2-3 times a week is the most effective. There may be a metallic smell in the product, which happens when a lot of ascorbic acid is used, and even using just about 0.23% of glutathione or ferulic acid can give off that characteristic Vitamin C scent. Start by applying a hydrating toner to protect your skin barrier. For high-concentration products, it’s also a good idea to apply them directly to acne scars or dark spots. As time passes, it tends to dry out, so it’s important to lock in moisture with a hydrating cream to prevent moisture evaporation. On days you use high-concentration Vitamin C, it’s best to avoid double cleansing. Some products are labeled for use both morning and night, but even when applied at night, the skin's turnover process will continue, and the effects will be sustained. It’s not recommended to apply it to freshly popped acne wounds. For optimal results, use the product within 1-2 months after opening. Since the formula may not stabilize, it’s recommended to use it within 6 months even before opening.
Top pick for acne-prone skin: Ultimate Multi Vita 10% Serum by THE FACE SHOP. The 2023 top pick, Physiogel Daily Serum, contains 6% ascorbic acid in a medium concentration and is focused on skin health, still a recommended product. This year’s top pick highlights the advantages of that formula, offering great effectiveness and value. It uses 5.5% ascorbic acid in a medium concentration and 1.8% ethyl ascorbyl ether, a Vitamin C derivative, for its brightening function. For antioxidants, it contains ferulic acid, which increases the stability of Vitamin C and E solutions, and calming ingredients like 2.7% panthenol, which provides hydration and helps protect the skin barrier. It uses a mixed technology of Vitamin C and betaine to increase the solubility and absorption of Vitamin C, according to research. While it may feel slightly heavy at first, it absorbs smoothly and has excellent moisture retention, maintaining a +40% moisture level even after 8 hours, thanks to the panthenol. Sensitive skin may feel a slight stinging sensation. When applied before bed, you may notice brighter skin and more even skin tone by the next day, with reduced acne scars and blemishes. This product uses 7.3% pure Vitamin C and Vitamin C derivatives for brightening and wrinkle improvement, along with 2.7% panthenol to prevent breakouts and soothe the skin. It helps lighten acne marks and brighten the complexion. Recommended for use 2-3 times a week, especially for oily, combination, and acne-prone skin.
Top Pick for Dry Skin with Scars: Vitamin C Serum by BENTON. This product contains 20% ascorbic acid, making it a high-concentration formula. It was selected because of its notable effectiveness in improving pigmentation, as confirmed by both professionals and testers. It includes 20% ascorbic acid and 1% ethyl ascorbyl ether. The serum also makes excellent use of antioxidant ingredients. Pure Vitamin C prevents melanin synthesis and provides strong antioxidant effects, while ethyl ascorbyl ether has both water- and oil-soluble properties. Apricot kernel oil, rich in unsaturated fatty acids and tocopherol, is used as a natural ingredient. The product is an anhydrous formula with Vitamin C dissolved in propanediol as a solvent. While the texture isn’t particularly pleasant, the use of an airless container enhances its oxidation-prevention capabilities. The creamy formulation minimizes dryness, and when applied, it gives a radiant glow. Thanks to the natural oiliness typical of Vitamin C, the skin looks visibly improved even in the morning. With a pH of 3.24, the formula is mildly acidic. Although there was a slight stinging sensation, it disappeared quickly, leaving the skin texture smoother and more refined. As someone with non-sensitive combination skin, I was pleased to see an overall brightening effect, and even with just a semi-matte cushion applied, my skin had a radiant, smooth glow. This product boasts 20% pure Vitamin C (high-strength) and 1% Vitamin C derivative, offering brightening and wrinkle improvement benefits. It hydrates without tightness, effectively cares for acne scars and skin texture, and is recommended for night use, twice a week. Ideal for dry, combination, or acne-prone skin, but those with seborrheic, atopic, or sensitive skin should use it with caution.

The 2020 top pick, Missha Vita C Plus Spot Correcting & Firming Ampoule, remains a recommended item due to its relatively high concentration of Vitamin C derivatives. Last year's top pick, Innisfree Green Tea Enzyme Spot Toning Serum, has also been renewed with some changes to its formula. It’s been renewed. The natural exfoliating agent, protease, has increased in concentration from 100ppm to 150ppm. This product minimizes pores slightly while improving overall skin tone, making it another solid recommendation. As for the WHITE GLOW AMPOULE by S.NATURE, it combines a base of moisturizing, soothing, and skin barrier-supporting ingredients.

With 2% niacinamide and well-utilized antioxidant ingredients, it’s a non-greasy yet deeply hydrating ampoule that includes soothing and barrier-supporting ingredients for low-irritation, making it perfect for daily use and highly recommended for sensitive skin.
Top Pick for 2023: Trouble and Pigmentation. The 2023 winner, Numbers-In Blemish Ampoule, which was praised for addressing hidden spots, remains a recommended item. The VITA ENERGY BLEMISH CLEAR AMPOULE by Lanbelle has been selected as the top product for its ability to prevent breakouts and effectively address long-standing, hidden blemishes. 5% High-Concentration Niacinamide. It helps reduce pigmentation. Tranexamic Acid targets hidden blemishes and helps prevent and alleviate hyperpigmentation caused by sun exposure. Ethyl Ascorbic Acid is a Vitamin C derivative that enhances skin brightening and provides antioxidant benefits. It contains approximately 1% panthenol as a soothing ingredient, along with barrier-supporting ingredients such as madecassoside and cholesterol. It features a transparent water-like texture and absorbs very quickly. One of its strengths is that it layers well without causing makeup to clump or smudge. On days with excessive sun exposure, soaking a cotton pad and using it as a pack significantly enhances its effectiveness. The product also helps control sebum in the nose and pore areas, slightly reducing pore size. Regarding hyperpigmentation like melasma, users have reported feeling that their dark spots have lightened slightly, which was appreciated.

2023 Anti-Aging Top Pick Recommended for aging or mature skin: VITAMIN C BOOSTING AMPOULE 25 by Easydew. The previous top pick, COSRX Serum, featured 23% ascorbic acid and well-utilized panthenol for soothing. It’s still highly recommended.

The formula uses ascorbic acid dissolved in water and propanediol, offering a satisfying application experience. While the texture is slightly heavy, it absorbs well, leaving the skin feeling hydrated with no dryness. Despite the high vitamin C content, it’s not overly oily and minimizes greasiness. Initial application may cause a stinging sensation, and the product emits a metallic smell due to the high concentration of ferulic acid and glutathione and the absence of fragrance. Personally, I found this aspect acceptable. I used it every three days, and the recommended usage period after opening is two months. When applied after toner and followed by a hydrating barrier cream, it prevents both surface and deep dryness, keeping the skin hydrated until the next morning. 23% High-Concentration Pure Vitamin C, 2% Vitamin C Derivative: Brightening and Anti-Wrinkle Functionality. It provides hydration without tightness, making it suitable for all skin types from dry to oily, particularly for those concerned with aging. Individuals with seborrheic dermatitis, atopic dermatitis, or sensitive skin should exercise caution.
I’ve explained the ingredients and their concentrations in detail. Choosing a product that suits your skin type is absolutely crucial. Make sure to follow the packaging instructions, usage methods, and precautions carefully. Keep in mind that the formula may oxidize and discolor within 2-3 months, and you might feel like it’s not effective at all during that period. You need to consider all these factors to experience the product’s full effects properly. That’s all for today’s review. This has been Director Pi. Goodbye!
