Hello so i have really sensitive skin since my skin barrier is damaged but my skin is also very dry. Is this the best product to use for my skin or do you recommend something that is more skin sensitive? I just would not want to irritate my skin more or damage it

Hi! Marine Hyaluronics is great for hydration. However, you may wish to explore Hyaluronic Acid 2% + B5 instead which has added ceramides specifically for barrier support.Was this answer helpful to you

Malar bag reduction

Provides decent surface hydration. Nice alternative to hyaluronic acid if you live in a very dry environment. Also, I perceive a moderate brightening effect from daily use. Would recommend.

This product is a good product but it's very watery and runs down your face super fast when you apply it.

Bottom Line No, I would not recommend to a friend

This serum is "meh." It didn't hurt my skin, but didn't help it either. It's very watery and not as hydrating as other products on the market. Save your money and go with something else.

Bottom Line No, I would not recommend to a friend
