LEVEL 1 – pH OPTIMUM RETINOL SUSTAINING – 1000 IUs
İ have never been able to use retinol products before because of my very sensitive skin. Dr Koo urged me to try and it has been gentle, but efficient on my face with notible skin improvement.
Using every night. I am seeing a definite difference in skin tone , sun spots are significantly lighter. Skins feels firmer. Highly recommend
This formulation of Retin-A is so easy to use and very gentle on my skin. I’m loving it!
As someone with sensitive skin, I've tried retinols in the past and they were always too harsh for my skin. It scared me off and I've avoided the category for years. This product is amazing and like no other retinol I've tried before! It glides on my skin, leaving it feeling silky and looking brighter, more even and glowing. It's so gentle but incredibly effective. I cannot recommend it enough!
The Retinol level 1 is keeping my skin smooth and comfortable 😊. I'm pleased with the results. I like all the products 👍
