Makes me look like I’m wearing foundation when I’m

I bought this looking for a good winter moisturizer sink my skin was getting very dry and itchy. I have sensitive skin and this did not cause any irritation or breakouts which is amazing! It has a nice thick consistency so only 2-3 drops are needed to cover your face. I’ve noticed since using this the redness in my cheeks have gone away along with fine lines. It leaves my skin feeling hydrated, smooth and blemish free! 10/10 recommended this product!

Love this serum!

I am 54 yo and was finding my makeup was looking cakey or thicker when I was wearing it. This product has helped moisturize my skin, and makeup looks so much better!

Magical Serum

This is a magical serum. I use it twice weekly. The serum is light, absorbing quickly, and seems to radiate a natural glow from my complexion. I keep this gem stocked at all times.
