This product is absolutely amazing. I initially got it as a sample and just had to purchase the full size. This is a high strength retinoid without the irritation, peeling and flakiness. I saw improvement in my skin texture and pigmentation soon after using it. The serum is light weight and sunk into my oily, acne prone skin immediately. I have used many Sunday Riley products and this is by far the best. If you are in the market for a serum, look no further! You will wake up with an even, glowing face. It was a pleasant surprise to find a deluxe sample of the CEO Glow and the Good Genes in the box, nice touch!

I use this at night along with Sunday Riley Luna oil over the top and it's amazeballs. Will never stop buying Sunday Riley products they are just brilliant.

High strength and very comfortable on the skin. I followed the instructions, eased myself into this gradually and didn’t suffer any irritation. Made my skin lovely and radiant .
