Retinol has been used as a skincare ingredient  because of its excellent skin efficacy. However, it is relatively difficult to make high retinol concentration because it is unstable against ultraviolet rays and the higher the retinol content, the lower the stability. To solve this unstable problem, not only the development of various retinol derivatives but also the techniques for stabilizing retinol are constantly being studied.​

Vitamin C is one of the core elements to make collagen, an essential component of our skin. And if we lack vitamin C, collagen synthesis decreases, and the skin loses elasticity.

Therefore, vitamin C is an ingredient that fills collagen, improving elasticity and wrinkles.

Just like we take vitamin supplements daily, using vitamin C products consistently is important.
