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).

Not Hydrating Enough
Style: Updated Formula
Non greasy but is not moisturizing enough for my dry eczema prone skin.

Perfect ball for dogs!
Size: Medium, Style: Medium (4 Pack), Size: Medium, Style: Medium (4 Pack)
Love these balls for my dog. They have a nice weight to them so you can throw them far. The material is very bouncy, so they do sometimes bounce over my fence, but they are very tough and not easily destroyed / very chew resistant. My dog is ~65lbs, it’s a perfect size for her, and she loves these and regular tennis balls the most. She is still able to squeeze it in her mouth, so it still has some softness / some give for her to enjoy.

Perfect toy for my corgis!
Size: Medium, Style: Medium (4 Pack)
Durable enough for my two corgis. Nonstop chewing cannot destroy these, highly recommend it!
