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.
