This product also contains Vitamin C (Ascorbic Acid) 3.80% - 5.80% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
Panthenol (pro-vitamin B5) at about 0.35% - 0.80% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
Humectants (panthenol 0.35% - 0.80%, sodium hyaluronate 0.45% - 1.10%, arginine 0.90% - 1.35% and glycerin 1.30% - 1.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging

Evens skin tone

What does the product description say?

Cos De BAHA Vitamin C 15% Ascorbic Acid Serum helps fade the appearance of sunspots, redness, hyperpigmentation and dark eye circles.

Source: Lila Beauty

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: arbutin.

arbutin 2.9% - 4.3%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin

ascorbic acid 3.8% - 5.8%

Irritation risk:

Concentration: Insufficient!

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

camellia sinensis leaf extract 0.15% - 0.6%

Irritation risk:

Concentration: Insufficient!

Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation

Moisturizing

What does the product description say?

Hyaluronic Acid deeply hydrates and plumps the skin instantly hydrating, replenishing, and boosting the skin's ability to retain moisture, revealing a smoother youthful complexion.

Source: Lila Beauty

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: arginine, 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: arginine, aloe barbadensis leaf extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

arginine 0.9% - 1.35%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin

glycerin 1.3% - 1.9%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

panthenol 0.35% - 0.8%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps attract water to the upper layer of the skin and can help improve skin barrier function

Anti-oxidation

This product contains antioxidants (arbutin) 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.

arbutin 2.9% - 4.3%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin

sambucus nigra flower extract 0.1% - 0.35%

Irritation risk:

Concentration: Effectiveness: LOW

A plant extract that might help neutralize free radicals in skin

ascorbic acid 3.8% - 5.8%

Irritation risk:

Concentration: Insufficient!

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

Anti-aging

What does the product description say?

Contains 15% ascorbic acid and is designed to target the most common signs of aging including brightness, firmness, fine lines, wrinkles, dark spots & sunspots.

Source: Lila Beauty

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.

This ingredient arbutin might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

ascorbic acid 3.8% - 5.8%

Irritation risk:

Concentration: Insufficient!

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
