Recently I tried Beauty of Joseon Light On Serum Centella + Vita C 30ml the one that most people talks about now! Its a gel type serum and super light-weight. Comfortable to apply on skin for the whole day as the texture is non-sticky type. They are visible effect in 2 weeks without drying out the skin as stated. After trying i can tell my skin become brighten and well hydrated than before and no other issue for me less than 2 weeks ! Very low irritation suitable for sensitive skin. Besides, the special of the airless pump container blocks inflow of light and for a long-lasting of the product. The main benefit I can see from this Vitamin C is skin brightening as it’s 3-O-Ethyl Ascorbate. Some studies show 3-O-Ethyl Ascorbate has anti-inflammatory and collagen production benefits as well. Centella has great wound healing, anti-inflammatory, and antioxidant properties so this will be great for sensitive skin types. Love it! Get yours now !
