Product Summary
"Today's Cosme - Vitacos 20 Serum" could be helpful for: Evens skin tone and Moisturizing, but its actives are not the most effective or are not well-studied.
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.

Works for
Anti-oxidation
This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A 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
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging

Moisturizing
What does the product description say?
Brand from Japan Today's Cosme. 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:
glycerin, hydrolyzed collagen.
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.
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A 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
Used 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
