As opposed to previous retinols products I have used in my endless quest to sustain my youthful appearance, this is a very, very effective, yet non-irritating nor harsh retinol product that actually DELIVERS what it says it will deliver!! Absorption This absorbs rather well for a retinol product, instead of a dry and sticky feeling, it actually goes on very smoothly and leaves behind a nice, almost silky feeling on my skin. I cannot top touching it after I have the product on! Doesn't Clog Pores I had a few breakouts when first starting using this product, but I attribute that to my skin sort of " purging" itself and not from the retinol itself. my skin breakouts cleared up within a couple weeks of use and I haven't had another since. Effectiveness Wow! I actually saw an improvement within a few days of use. I started out with using it every 3 days, than increased to every other night, which is how I use it now. My skin clarity, fine lines, overall appearance is wonderful.
