I’d like to recommend the Dr. G Black Snail Retinol Ampoule that I’ve been using lately. I bought it at Olive Young. It is a functional cosmetic product for whitening and wrinkle improvement. With consistent use, it restores elasticity to enlarged pores, providing a lifting effect. Although retinol can sometimes cause sensitivity, this product is gentle and low-irritation, so I think it is suitable for daily use. I recommend it to those new to retinol.
