"COSRX - Advanced Snail Peptide Eye Cream" has a good moisturizing formula. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Acetyl hexapeptide-8, arginine, betaine, glycerin and snail secretion filtrate in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, arginine, helianthus annuus seed oil and palmitic acid) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- We particularly like that there is a good concentration of Niacinamide (1.50% - 2.20%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. 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 help improve the skin tone, reducing pigmentation marks.
- We like that this moisturizer contains peptides (palmitoyl tetrapeptide-7 0.10% - 0.35%, palmitoyl tripeptide-1 0.10% - 0.35%, palmitoyl pentapeptide-4 0.05% - 0.25%, acetyl hexapeptide-8 0.05% - 0.30% and copper tripeptide-1 0.10% - 0.35%). 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. Peptides 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 0.10% - 0.45%. 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).
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin
