As with any retinol product, it claims to reduce fine lines and wrinkles and decrease the signs of aging. It contains vitamin A, panthenol, adenosine, and tocotrienol. This is to be used as the last step of the skincare routine in the moisturizer step. I've been using it 3 times a week and I haven't experienced any irritation at all, which is great! There is no detectable fragrance, which is another plus in my book. It will obviously take long term use to see if there are any results. One thing that I saw on the packaging was that it is advised to refrigerate this after opening. Personally, I've never used a retinol product where refrigeration was advised. It makes me question whether that's really necessary as well whether the efficacy of this product will decrease if I don't refrigerate it. I haven't refrigerated as this is very inconvenient for me and my skincare routine.
