Dermatologist recommended it!
Size: 1.3 Ounce (Pack of 1)
This is my 11th order of this product. I originally started using it a few years ago when my dermatologist recommended it during a period of hormonal acne. I’ve been using it ever since. I have very sensitive skin that usually reacts to almost everything, either with redness or breakouts, but I can use this cream comfortably without any issues. It is very gentle, deeply hydrating, and has become a permanent part of my skincare routine. It is definitely worth the price. Even a small amount provides excellent hydration and it lasts a long time. I also love that it has a natural ingredients and is fragrance-free.

Game changer.
Size: 1.3 Ounce (Pack of 1)
I moved out to Arizona back in 2020 and shortly after that, I became a reptile. My skin would become flaky and peel and I tried several different types of facial creams and lotions with no luck. I went to a dermatologist who recommended CeraVe, and it did help my skin to an extent. It took care of the flakiness, but I would still see the dryness, especially when I looked in the mirror up close. I recently was on Google doing a search and came across this brand. I thought I’d give them a try and though I was skeptical, my skin has not looked this good in years. My skin feels smooth, hydrated and NO greasiness. I highly recommend this product.

Cleared up my flaky skin problem, helps keeps my facial skin soft year round
Size: 1.3 Ounce (Pack of 1)
I bought this full-size tube of Avene Hydrance Optimale Rich Hydrating Cream after falling in love with a small sample tube that came in a subscription box. At the time I received the sample, I was battling an unusual case of dry flaky skin that was embarrassing. Within a few days of regular use, my skin looked like new. Soft and clear. The tiny sample lasted a long time, so I didn't hesitate to buy the full-size tube even at this price. I use this every morning and night after cleansing my face. My skin stays soft, even with the dry winter skin and drying indoor heat. My makeup glides on smoothly. This is my go-to moisturizer year round now. Another reviewer mentioned being concerned her product may be counterfeit. I only buy products like this when it says Sold by Amazon and not a third party so I make sure I get authentic, fresh products every time.

Avene RICH face cream
Size: 1.3 Ounce (Pack of 1)
This is a good product that was recommended by my Dermatologist. As written in a previous review, I prefer the LIGHT product. This is very good but too heavy for my face.
