My skin was dry before menopause
Size: 1 Fl Oz (Pack of 1)
I’ve had dry, sensitive skin all my life. Post menopause? It’s extra extra dry. I put this under my eyes and around my lips and my concealer/foundation doesn’t settle into my lines/wrinkles.

Temu size for Amazon price
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
This lotion is great. I feel like I got ripped off. I wish I read how many ounces it was before purchasing it. Boy was I surprised paying amazon price and receiving Temu size. That is AA battery for comparison.

I should check the size
Size: 1 Fl Oz (Pack of 1)
This wasn’t the lotion I expected but I should Probably check the sizes before ordering. This is a mini bottle. Not as moisturizing as I’d hoped for. Very light water consistency. Not my favorite lotion.

Hand lotion
Size: 1 Fl Oz (Pack of 1)
This lotion does what is said it will. I used it and my hands are extremely dry from washing them all day while at work. Once I’m home I use it and my hand feels silky smooth without the greasy feel afterwards.

SMALL! Don’t waste your money!
Size: 1 Fl Oz (Pack of 1)
I should’ve looked closer when purchasing because this is a super small sample size that isn’t even as big as the travel size and yet I paid as much for it as a regular size. What a joke! The product itself is great but I would’ve never ordered this size if I’d known it was going to be sooooo small. What a ripoff!
