SkinMedica Age Defense Retinol 1% Complex 1.0 fl oz (29.6ml)

Per Dr. Dray, dermatologist (see You Tube), reviewed a trial/study that supports the same anti-aging results (improved collagen absorption with fewer fine lines and wrinkles) from the SkinMedica Retinol Complex when compared to Tretinoin. The main difference is that the SkinMedica product demonstrated less irritation and inflammation. I am very sensitive to tretinoin irritation and the SkinMedica works better for me: at least to this point I have been able to use the SkinMedica every night without breaks. I am grateful for less irritation and the anti-aging results I expect from Tretinoin.

Veery excellent product, I use three times per week nightly.
