Eudermine Activating Essence.

"Essences are a huge part of Japanese and Korean skincare culture and they're almost like a watery toner essentially but not used quite the same way. They're put on immediately after cleansing before serum and they do a couple things. Number one, it helps to soften the skin, add back additional hydration to the skin. Two, it helps to actually improve penetration of skincare ingredients through a couple mechanisms because you're rehydrating the skin, but often they will contain ingredients. In particular, in Japanese skincare, essences often contain fermented ingredients that naturally help with [...] fermentation with acids that will actually naturally improve skin cell turnover and thereby enhancing the penetration of ingredients that you use afterwards. This is a really elegant lightweight essence that number one promotes skin moisture balance, improve radiance and dullness and again with ingredients in here improving skin turnover and thereby enhancing the penetration of the products that used afterwards. It helps to visibly improve fatigue making your skin look more bright and energized and refined and ingredient wise contains two types of hyaluronic acid and this is really important because then you can penetrate various layers of the skin improving moisture retention."
