I am a beauty, skincare and fragrance enthusiast. I have been recently trying the Cosmedix Duo A Nightly Retinoid Treatment. I struggle with texture on my skin, as well as fine lines and wrinkles and so I am always looking for an effective retinol. I like several things about this product. First, I like that this has not only retinol, which is a sustained release, but retinal, which is fast acting and extremely effective. Second, I really appreciate that this treatment is not drying like most retinoid products. Instead, it is hydrating and leaves my skin feeling smooth. This would be great for advanced retinoid treatment users, as well as anyone who struggles with dry or sensitive skin. I will continue to recommend this, and will repurchase when I run out.
