Feels good on the skin not greasy
Size: 1.3 Fl Oz (Pack of 1)
Very nice product very concentrated has a very light fragrance that dissipates very quickly not greasy. No I do not have any redness or sensitivity I wanted to try this product anyway because I'm always looking for moderately priced good quality that travels well. And this fit the bill especially with it being on sale.

Good product , but
Size: 1.3 Fl Oz (Pack of 1), Size: 1.3 Fl Oz (Pack of 1)
It seems to be a good product and it’s not too heavy , but still caused few breakouts here and there . Also, Avenue always has protective foil on their cream , this one didn’t have (I replaced it but new one also didn’t have it). Also, it goes away really fast because it’s only 1.3 ounces.

Gold Star
Size: 1.3 Fl Oz (Pack of 1)
This cream is truly gentle and healing for a compromised skin barrier. I prefer this cream in the winter, when the weather is dry, and after procedures like microneedling or laser. It has never irritated my skin, and does soothe and heal. The La Roche Posay cicalfate cream is also excellent, I think it is slightly less rich, so I prefer that in humidity or the summer.

Overpriced but it works.
Size: 1.3 Fl Oz (Pack of 1)
I hate that I love this product. It's stupid expensive. But it's great for broken/damaged/recovering skin. I've used it post microneedling and it is the only thing that soothes, hydrates, and doesn't sting raw, red skin. Great for rashes/hives and allergic reactions too. Luckily a thin layer is often enough to do the trick. so it lasts a long time I wouldn't use for everyday moisture, but when your skin is angry, this stuff works. (Overpriced? Yes. Witchcraft? Maybe. Does it work? Yep.)
