What the product description says
“VITACOS20 Serum contains 2 types of Vitamin C moisturizing and quick-acting.”
Source: Yesstyle

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: 3-glyceryl ascorbate, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: hydrolyzed collagen.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.7–4%
3-glyceryl ascorbateKey active· HumectantEffect: HighA moisturizing vitamin C derivative. It is considered to be one of the most stable ones. It is effective in neutralizing free radicals and can help to even out the skin tone if used in high enough concentration~2.2–3.3%
Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~1.3–1.9%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.4–0.95%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~5.2–7.8%
Evens skin tone
Side benefit · 3-glyceryl ascorbate, 3-o-ethyl ascorbic acid
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: 3-glyceryl ascorbate

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: 3-o-ethyl ascorbic acid.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

3-glyceryl ascorbateKey activeEffect: HighA moisturizing vitamin C derivative. It is considered to be one of the most stable ones. It is effective in neutralizing free radicals and can help to even out the skin tone if used in high enough concentration~2.2–3.3%
3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.5–2.2%
Anti-oxidation
Side benefit · 3-glyceryl ascorbate, 3-o-ethyl ascorbic acid
Works well

This product contains antioxidants (3-glyceryl ascorbate) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - 3-o-ethyl ascorbic acid also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

3-glyceryl ascorbateKey activeEffect: HighA moisturizing vitamin C derivative. It is considered to be one of the most stable ones. It is effective in neutralizing free radicals and can help to even out the skin tone if used in high enough concentration~2.2–3.3%
3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.5–2.2%
Anti-aging
Side benefit · 3-glyceryl ascorbate, 3-o-ethyl ascorbic acid
May help

This product contains 3-glyceryl ascorbate. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

3-glyceryl ascorbateKey activeEffect: MediumA moisturizing vitamin C derivative. It is considered to be one of the most stable ones. It is effective in neutralizing free radicals and can help to even out the skin tone if used in high enough concentration~2.2–3.3%

Product summary

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (2.40% - 3.60%) it cannot have a noticeable benefit for the skin.
  • Humectants (sodium hyaluronate 0.50% - 1.15%, hydrolyzed collagen 1.40% - 2.00% and glycerin 2.90% - 4.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
