Product Summary
"COSRX - Buy Cosrx The Vitamin C 13 Serum in Australia - Korean Skincare and Cosmetics" is effective for: Evens skin tone, Anti-aging and Moisturizing
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 (13.00% (declared)) it cannot have a noticeable benefit for the skin.
- Adenosine 0.35% - 0.85%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
- An effective concentration of Panthenol (pro-vitamin B5) - about 1.70% - 2.60%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (sodium hyaluronate 1.10% - 1.60%, acetyl glucosamine 1.50% - 2.30% and panthenol 1.70% - 2.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid, acetyl glucosamine, adenosine.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: tocotrienols.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
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

What does the product description say?

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
In addition, this product contains acetyl glucosamine, glutathione. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
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, glycyrrhiza glabra root extract.
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.

Moisturizing
What does the product description say?

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:
sodium hyaluronate, butylene glycol.
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: squalane, elaeis guineensis oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, panthenol
