Review

for the price point of this moisturizer i feel like i expected a lot more?

i mostly used this moisturizer at night paired with my tretinoin and i found that the 2 worked well with each other. it’s a really nice almost gel-like cream texture with a light fragrance. i found it a little hard to blend while my face was still damp which is when i usually apply moisturizer. i don’t feel like it did Show more

My HG facial moisturizer. It makes my face feel so soft and velvety. It dries quickly, is gentle even when my face is on fire and it has a slight "chemical" smell that I tend to like. I love the pump as well. I use this when I need a good hit of luxury.
