I have super sensitive skin but also really really want to try a good retinol product to help with like everything. Brightness, anti wrinkles, hyperpigmentation, pore care, you name it retinol does it. Since this is a 0.5 retinol product, CosRx has done a great job formulating it with squalane and vitamin 5. It's quite gentle (mind you I really buffer and has been using it only once a week to start after my moisturizer).
I would recommend for those who had experience with beginner retinol and want to progressively increase the strength but worry about irritation.
