ASTALIFT WHITE PERFECT UV CLEAR SOLUTION is an UV serum for daytime use with an originally developed UV protective agent that blocks all UV wavelengths reaching the skin including Deep UVA that damage the skin’s subsurface, causing brown spots, wrinkles, and dullness. Astaxanthin, the effective ingredient that blocks the Deep UVA, is expressed with a clear cap on which a red graduation and a crystal cut are provided. The center of the cap is made of a special resin that changes its color when reacting with UV of all wavelengths (UV detection function), and provides the user with awareness and joy of using by making the UV visible.
