Treasure!! The best!!
I had been using Avene Compensating cream for years before it was reformulated and renamed as “Revitalizing” in (as I remember) 2020. At the time, every single comment I saw complained about its pilling and its getting worse after reformulation. Every single comment wished for the old formulation back. Because Avene Compensating was PERFECT for me, I got very anxious after reading the comments and decided not to purchase the new Revitalizing cream. I jumped around from products to products for the last 2 years (from expensive La Mer cream, Cle de peau La Creme, Lancome soft cream, Amorepacific Time Response to less expensive Clarins Hydra, Embryolisse). Nothing beat Avene Compensating cream. Nothing came close to Avene Compensating cream in terms of giving my easily irritated skin that clear, well moisturized, trouble-free, healthful look. Fast forward to the week of Thanksgiving 2022 after I got back from a Las Vegas trip with terribly dry and dehydrated reddish skin that nothing helped (and I always use sheet masks daily), I decided to give Avene Revitalizing a try. Worst case scenario, I would waste my $40 that I, very likely, would otherwise waste on another non Avene moisturizer. I’m so grateful I gave it a try. I don’t know if Avene listened to its loyal customers and brought the old formulation back, or if they improved the new formulation that pilled, but the Avene Revitalizing cream (I tried both rich and regular versions) did not pill at all for me and as far as I can still remember, Avene Compensating cream felt the same to me. After 2 nights of Avene Revitalizing, my skin is pretty much back to normal now. I think this is the old formulation but I can’t say for sure because it was more than 2 years ago when I last used the cream, but no matter what, if it keeps being what it is now, I will be a customer for life. Please Avene. Don’t change formulation again.

okay moisture
Average moisture, I like it without any fragrance. But it is easily peeling if you used other product after this. Probably won’t buy it again.
