The research-based derma line of COSRX was born, a prescription solution that optimally blends customized high-efficiency ingredients to solve skin problems and delivers them safely and effectively to the skin.
It is a deep elasticity care product that was born after research for firm and strong skin.

Use this product when you see unprecedented fine lines around the eyes and mouth, when you are worried about the texture of loose and sagging skin, when elasticity or dryness does not improve, or when you want to give your skin a healthy glow.
Recommended for intermediate users who are looking for a step up from low-content retinol, use it more intensely with high-strength pure retinol that cares for elasticity more deeply.

It has a silky oil formula that penetrates lightly and provides glow to the skin.
Due to the characteristics of the retinol component, the color may darken or there may be a unique odor.
Feel the multi-care nutrition without burdening your skin as it gently penetrates without being heavy or sticky!
It helps to provide moist and shiny shine, soft moisture, strong skin barrier, smooth skin texture, strong skin elasticity, and nourishment during the night.

Many retinol products use a relatively easy-to-develop retinol derivative (retinyl palmitate) instead of pure retinol, which is sensitive to light and heat.
It blocks aging concerns by prescribing highly concentrated ingredients that help with special elasticity care along with pure retinol.
It contains super vitamin E, which is up to 50 times more effective than tocopherol, and contains 91% vegetable squalane, which is a moisturizing factor that is skin-friendly and moisturizing.
