What it is
This is the first-ever medicated pre-serum developed by Hythiol, drawing on over 50 years of research into blemishes. It features three carefully selected active ingredients—tranexamic acid, niacinamide, and D-pantothenyl alcohol—and Hythiol's unique, Japan-first formula*1, which targets the causes of blemishes*2 and wrinkles. It also contains L-cysteine and vitamin C derivative (3-O-ethyl ascorbic acid) as skin-conditioning ingredients. Furthermore, its three-phase spherical lamellar technology*3 moisturizes the skin, and beech extract*4 encapsulated in nanocapsules penetrates deep into the skin*5, providing long-lasting hydration. This single product offers four functions: whitening*2, wrinkle improvement, prevention of rough skin, and moisturizing. It provides a non-greasy yet deeply moisturizing feel, with a pleasant, subtle citrus scent. *1 A formula combining active ingredients (niacinamide, tranexamic acid, D-pantothenyl alcohol), skin conditioning ingredients (L-cysteine, 3-O-ethyl ascorbic acid), and tri-phase spherical lamellar technology.

Ingredients
How to use
1. Use in the morning and evening on clean skin after washing your face. 2. Take 2-3 pumps into your palm and apply evenly to your entire face. Handle cosmetics with clean hands. When using for the first time, press the pump several times until the contents come out. If any contents stick to the container after use, wipe it clean with a clean cloth and close the cap tightly. When moisture evaporates, the whitening active ingredient may rarely crystallize, causing the mouth of the container to become rough, but this does not affect the quality. Keep out of reach of infants and children. Do not store in extremely hot or cold places or in direct sunlight. Due to the characteristics of the contents, discoloration or sedimentation may occur, but this does not affect the quality.
