PYUNKANG YUL Calming Moisture Serum for Strong Daily Moisturizing Power, Skin Revival & Soothing Care with Centella Asiatica, Tea Tree, 5 Hyaluronic Acids, Ceramide | Korean Skin Care Moisturizing Serum | Safe on Acne Prone and Sensitive Skin

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: allantoin, arginine.

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, ethylhexyl palmitate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide np, madecassoside, palmitoyl tripeptide-5

This product contains acetyl hexapeptide-8, asiaticoside, centella asiatica leaf extract, madecassoside, palmitoyl tripeptide-5. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

This product contains antioxidants (asiaticoside, madecassoside) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - camellia japonica flower extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
