returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Miracle cream
Size: 13.5 Ounce (Pack of 1)
I have been having crazy acne due to a severe reaction to salicylic acid, among other things. My face was incredibly inflamed, itchy, sensitive, red and painful. My dermatologist started me on an oral antibiotic and a clindamycin/benzoyl peroxide topical. The topical was still drying me out quite a bit so I got this lotion and it's literally a miracle cream. My skin is hydrated, no itchy or stinging and the redness has gone down so much. It's also helping my open sores to heal more quickly. Yes, it's a combination of all 3 products working together but I can definitely see and feel the cream repairing my skin barrier. I will be starting on accutane after a month of antibiotics and will continue to use this balm to keep me from drying up like a prune.
