I think this is a good moisturizer, as far as anything else it claims such as an even skin tone, I wouldn’t agree. I used the bottle and didn’t notice any changes in my skin and blemish appearance. It’s not too thick and it’s not greasy. I will say I had a successful run with brightening my inner thighs. I added this to the mix, and for some reason, I began chafing leaving Little bumps in my inner thighs that turned into 50-60 dark spots 😭 I’ve never had a problem with chafing or dark spots from bumps in my inner thighs before. I’m not sure if it because I was using it in conjunction with something else it caused issues. I would recommend it as a lotion, but that’s it.

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.
