I thought you'd like to know because this website's product page leaves that info off. Interestingly Amazon includes this info.

This pure retinol is amazing. Real results and fast!  I was using the No7 Pure Retinol Night Cream and Eye Cream for about 4 weeks, which I love too, before upgrading to this 1% retinol concentration, and my skin only experienced slight sensitivity and peeling on initial use. I’m on week 3, and my skin tolerates it without issue, and my skin looks wonderful. The Post Retinol Soother Cream is nice too, I use that the day after, and it really helps with fast recovery.  I’m very pleased with this product, highly recommend, and will repurchase. LOVE IT! 

I’ve been using this for at least two years and it has transformed my skin.  It has softened fine lines and lightened sun spots.  It can be drying, so I alternate it with the night cream to prevent flaking.  Try it! You will be impressed!

I have been using No 7 Pure Retinol for a long period of glorious time! I have tried on occasion more expensive priced retinol products; but I have honestly not found any retinol product on the market that delivers the quality retinol No 7 delivers! I start every day with a beautiful complexion palette due to the results I receive with the nightly use of No 7 Pure Retinol! Indulge you will love yourself for it!

Love this product!  My skin looks so much smoother.  Would recommend to all my friends. 

I love this retinol product. It is stronger than the serums so follow the directions exactly & ease into it, if you use it too often it can burn your skin (make it pink) & you’ll notice peeling.  It’s a great product just follow the directions. I’ve noticed less fine lines & smaller pores. 

I received this as a free sample with my last order, and I bought more! I feel like it hydrates my skin very well and I see less lines in the morning. I use this with the Future and Renew Night Creme, and am seeing results. Thank you!

I love this product! My face is definitely smoother since using it. I use it in combination of the eye cream & night cream.

Pure Retinal is amazing!  When combined with the booster serum, the results can’t be matched.  I recommend No. 7 products to family and friends;  they are all as thrilled with these products as I am.

I love this product. I have never used retinol before. This is a game changer. My dark circles began to scab up and fall off. Other than a little peeling, this product had no down side for me.
