MEDITHERAPY Retinal Skin Booster Serum is a game-changer for my sensitive skin. The lightweight, watery formula glides on effortlessly without leaving a greasy residue, which is a huge plus. I noticed my skin felt noticeably smoother after just a few days, and the fine lines around my eyes and mouth began to fade.

I appreciate the 0.00 irritation index, which means I can use it daily without worry. The serum doesn't clog pores,so it's great for oily or blemish-prone skin.

The natural yellow tint is a nice touch, giving it a subtle, authentic look without artificial additives. A must-have for those new to retinol or seeking a gentle yet effective skincare upgrade.
