Great for liquid foundation
These are great quality and value! I saw them on a TikTok and thought the price made them worth trying. They apply product well and evenly and they last a decent amount of time as well.

Great for sensitive skin and people who sweat in the face.
I absolutely love this product My daughter introduced me to it. My skin is very dry however, I sweat so much in my sinus area and my skin is very sensitive. Most products are too heavy when I put them on and they make me sweat more or I feel like I need to get a papertowel etc and wipe it off. None of that with this. It's light, it moisturizes my dry areas and it does not leave a greasy or heavy feeling. It dosent make me sweat at all. Best of all it only takes a little. I use about a dime size and that works great. I only need to use once a day. I recommend this product.

Great for oily, acne prone and sensitive skin.. thank god!!!
I have oily, acne prone, sensitive skin. So boy oh boy is it difficult to find a moisturizer or really any face product in general that works and is affordable. This is light yet deeply hydrating, does not make me greasy, make my skin sting or break me out. In fact my skin feels less textural and more hydrated looking. I wish it was a bigger bottle but I’m surprised as to how little I need to use since it spreads so easily. (Only need a dime sized or a bit smaller) Great for under eye too so no need for eye cream. Will order more!

Great product, just not enough of it
Loved the product, kept my face looking healthy and smooth. It’s very lightweight which I appreciated. Didn’t notice a scent either which is also a plus. The only thing I was a little surprised by was the size. It was the size of one of those Clinique moisturizer samples they give you as a bonus when you buy a bunch of their makeup. I ran out pretty quickly even though I didn’t use excessive amounts and I don’t have a giant face. Other than that, I’d say this is a worthwhile addition to my skincare regimen.
