Product summary

"COSRX - Ac Collection Lightweight Soothing Moisturizer" 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. Panthenol, arginine, betaine, cyclomethicone and glycerin 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 (cyclomethicone, arginine, cetearyl alcohol and cetyl ethylhexanoate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
