The Most Concentrated Power for Skin, Lediffer.
Experience visible improvements and dramatic effects now.

Ultra-low molecular collagen (300Da), smaller than pores, delivers active ingredients such as glutathione and hyaluronic acid deep into the skin, providing visible tone-up and whitening effects.

In particular, this formula uses deep-sea Blackstone fish collagen, known for having the highest absorption rate among collagens, ensuring outstanding skin penetration. Combined with silk fibroin, it goes beyond ordinary cosmetics to deliver effects comparable to dermatological injection treatments.
