My Korean sis-in-law once told me that Koreans are obsess with great skin, and that is all about a bouncy, dewy, taut, and hydrated resilience. While most of Korean skincare products are totally different from those of the West, our skin needs to be hydrated and moisturized. Many moisturizers are designed to be water-based, in other words, they contain mostly water-binding ingredients to support general skin needs. However, dry skin will need both moisturizer and hydrating toner or serum. This is because the moisturizer will lock in the water from evaporation from the upper layers of the skin while the hydrating toner or serum will ensure the skin is well-hydrated.
