horrible reaction

Submitted 6 days ago

From rochester ny

had smooth, soft and clear skin aside from the occasional hormone pimple, and this gave me horrible texture. entire face has raised bumps, all over my throat and ears and red splotches. made my skin feel sticky after application despite having very watery texture. boyfriend used it and had no reaction, helped even out his skin pigmentation.

Elevated my serum step

I used to use regular hyaluronic acid after cleansing but have upgraded my serum step to this product. I really like it and feel that it revitalizes my skin noticeably.

Meh...not impressed

From Michigan

I received this as a birthday gift. This was my first time using a product using hyaluranic acid. I never saw any difference after two months of daily use. Plus, there was a sticky residue after each use.

Bottom Line No, I would not recommend to a friend

BEST serum for combo skin

Submitted 13 days ago

By Rosygal

From Tampa, Florida

As someone who has combo skin, I really enjoy layering lightweight products instead of using thick creams and serums. This serum I immediately noticed hydration and plump to the skin the next day. My fine lines near my mouth and in forehead less noticable. Its so light and my skin drinks it up. Paired with my gel moisturizer I feel like its the perfect skincare combination for my combo skin type as we enter summer.

Im absolutely in love with this product! Ive been using it for a couple of months. My texture has gotten more smooth and my dark spots lighten up. I made sure to follow the instructions on the packaging. It works too good! Will be a permanent staple in my skincare routine :3
