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).

SHORT-game Ball Launcher … love it!
Yes, this is a smaller ball launcher … It is for her SHORT Game! Love it AND the squeaky baseball that came with it is A-HIT!! Our black golden doodle, Josie, carried that around for hours … batting it around, jumping on it, resting with it right-next-to-her. For your pup’s LONG game, purchase the longer launcher. GAME-on!

Works great with tennis balls
I have a pretty large yard, and this thrower is great for my little Jack Russel puppy. It even picks up ball without having to touch all the spit.
