MY NEW FAVE
i am obsessed with this moisturizer: the price is affordable and it works beautifully. it's like a lightweight serum compared to thick moisturizers. it has clean ingredients, no fragrance, and leaves my skin feeling so soft with no greasiness

I’m enjoying it!
I’ve really been enjoying this moisturizer so far. It feels lightweight, comfortable, and absorbs nicely into the skin without feeling greasy or heavy. I also love that it is fragrance free. My skin feels hydrated throughout the day, and it layers well with the rest of my skincare products.
I also use the matching face wash and toner from this line, and together I’ve been very happy with the overall results. My skin has been looking smoother, healthier, and more balanced since incorporating these products into my routine.
One important thing to note is that this moisturizer does not contain SPF or sun protection, so make sure to apply a separate sunscreen during the day if that’s important for your skincare routine. Overall, I think this is a great everyday moisturizer and I’ll continue using it.

Lightweight moisturizer, worth it.
Love it! Its lightweight and silky. Makes my skin feel hydrated and smooth. I apply after cleansing my face..can't say if it actually provides 80hr moisture. So far so good. Would repurchase.

This is a pretty good moisturizer, im not sure if this gave me bumps on my face or it’s just a breakout, perhaps from one of my makeup brushes. Overall very moisturizing, doesn’t really have a sent, it is a little bit thick but not super thick.

I really love this moisturizer, I started using a retinal and since i usually dont ease into it, my face does get dry and flaky. I was using a different one and it would work for a little while then i would feel dry a while after. Thayers actually feels like it kept my face moisturized even the next morning. It took a couple days to feel it best because my face was already dry from the retinal, but after once my skin soaked it all in it felt great. Its thin, soft and light, not heavy. No scent other than the normal unscented lotion smell. I use it day and night. 14 dollars was questionable, but its so worth it.
