Product Summary
"YEOUTH - Retinol Duo" is effective for: Anti-aging, Moisturizing, Exfoliation, Evens skin tone and Anti-blemish
Ingredient callouts
- this product contains an effective form of Retinoids (vitamin A): retinol 0.20% - 0.35% and retinol 4.20% - 5.10%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Peptides (palmitoyl tripeptide-1 0.10% - 0.20%, palmitoyl tetrapeptide-7 0.15% - 0.30% and dipeptide-2 0.20% - 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. 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.
- Humectants (sodium hyaluronate 0.20% - 0.40%, glycerin 0.35% - 0.65% and sodium hyaluronate 1.70% - 2.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
The Retinol Duo by YEOUTH, consisting of a Retinol Serum and Retinol Eye Cream, is designed to enhance the overall look of the skin.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
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.
Two steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating

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, sodium hyaluronate.
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: dimethicone, oryza sativa bran oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
