. This might as well have been water. No change in skin
A friend and influencer recommended this for my sensitive, dry skin that has rosacea. I expected my skin to feel more hydrated and see reduced redness. Neither happened. ☹️
To give a full review it is unscented which is great. But I didn’t feel or see any improvement. I used it twice a day for at least two weeks.

68 years old and this hydrated thoroughly.
I’m 68 and take very good care of my skin. I’m not sure why but this product gives me a nice ( and lasting) boost of hydration. I don’t go in the sun after 12 pm - I have fair cool skin with minimal wrinkles but some sagging. I think my skin leans towards dry although I’m always on top of it so it looks and feel hydrated.

Buy!! Worked well for my eczema
Love love love this product!! It’s AMAZING for my winter skin. The consistency is thick enough to deeply moisturize and keep my skin hydrated all day long. It made my skin super clear, smooth, and healthy-looking.
It also really helped clear up my eczema, especially the eczema and dry patches on my face. My dry spots became so much smoother and less irritated after using this consistently.
The jar lasted me a good while, which I loved since I use moisturizer constantly. There’s no fragrance, the application is super easy, and the consistency feels sooo nice on the skin. It absorbs really well and leaves my skin feeling soft and glowy.
It honestly worked so well that I didn’t even need to use primer before my makeup anymore 😭 that’s how good this product is!! I will always repurchase, especially during the winter 💕
