One of my new year’s resolutions was to finally start using anti-aging products…and use them religiously. But I love trying new products (clearly) so integrating one product, long term, in my routine is tough. The trials of a beauty junkie. But this Retinol Fusion PM made the cut. My skin didn’t do well with prescription retinol products (think red, dry and peeling). So I was a little nervous using a product with retinol in it. The serum did not agitate my skin at all. In fact, it was soothing and moisturizing. I do think I have seen collagen improvement. A bonus is that it also has vitamin C & E. I know these products are an investment, but so far, it has been a good one for me.
