Product Summary
"COSRX - The 6 Peptide Skin Booster Serum" is effective for: Anti-blemish, Moisturizing, Anti-aging and Evens skin tone
Ingredient callouts
- A good concentration of Niacinamide (1.60% - 2.50%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Peptides (palmitoyl tripeptide-8 0.05% - 0.25%, oligopeptide-68 0.05% - 0.30%, dipeptide diaminobutyroyl benzylamide diacetate 0.05% - 0.20%, copper tripeptide-1 0.05% - 0.30% and acetyl hexapeptide-8 0.10% - 0.30%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
- Adenosine 0.20% - 0.75%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (dextran 0.05% - 0.25%, glutamic acid 0.05% - 0.25%, glycine 0.05% - 0.20%, sodium hyaluronate 0.05% - 0.25%, alanine 0.05% - 0.20%, pca 0.05% - 0.25%, acetyl hexapeptide-8 0.10% - 0.30%, sodium lactate 0.10% - 0.35%, sodium pca 0.10% - 0.45%, betaine 0.10% - 0.40% and glycerin 3.40% - 5.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, copper tripeptide-1, dipeptide diaminobutyroyl benzylamide diacetate, oligopeptide-68, palmitoyl tripeptide-8, serine, threonine.
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.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles

A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.

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: alanine.
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.

An effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin
Moisturizing
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:
alanine, betaine.
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: glycine soja oil, caprylyl glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, copper tripeptide-1, dipeptide diaminobutyroyl benzylamide diacetate, niacinamide, oligopeptide-68, palmitoyl tripeptide-8
