A very good product, does not cause irritation. my skin is very dry and even so I had no discomfort.

It’s nicely formulated but definitely too strong for sensitive skin.

My skin is sensitive so retinol was not easy to incorporate into my routine in the beginning. However I had seen a video review of this product which is said to be used on models and show business people. I gave it a try and it worked perfectly. Next day my skin looks really good!  I think I won’t stop repurchasing eheh 

This is a very good product, the lactic acid is very hydrating. I somehow feel that the retinol content is bit less than the claimed 1% after trying some other brands.

This is the only serum which keeps all its promises! High efficacy, excellent tolerability. Before buy the big size I purchased the little format because I was afraid about tolerability. But without any irritations in just 2 weeks Iachieved excellent results: less wrinkles, firmer skin, less discoloration! Inlove it! 😘🥰😍
