It really hydrates
I havent used it long enough but so far so good. I haven't had any reactions to it. It is really oily so I personally do not use it during the day becaus ei dont like looking extra oily. But at night is really good.

Good, but not for super oily skin
My skin is oily in my t zone especially my nose area due to my large pores. I wanted to find a ceramide cream to help protect my skin barrier when using retinoid at night. This product is heavy and had me waking up with a greasy and oily t zone in the morning. I think it would be great for dry dehydrated skin but not for me. It does make my skin feel soft though. I haven't experienced any breakouts due to it either. The bottle is small but a little definitely goes a long way with this as it is rich like the name describes. I also love how it doesn't have a fragrance at all. Everything about this product is pretty good, its just not suited for my skin personally due to my skin being naturally oily already.

It’s good and non irritating
Perfect for daily use, it’s lightweight so if you have very dry skin (like me) u may need to use thicker moisturizer but it’s still pretty good. U can still wear make up afterwards with no issues which I loved

Excelent daily moisturizer
This is a nice, thick, ceramide rich moisturizer that provides great occlusion. I have really dry skin, and this is like a big drink of water for the face.

Hydrating Night Time Lotion
This product is so rich and hydrating. I wake up in the morning and my skin still feels hydrated. It is an amazing product especially for the price. I have tried many lotions and this is the best like literally better than high end ones.
