My Skin Loves It
Love this serum! It hydrates deeply without feeling sticky and makes my skin look healthy and glowing. A must-have for daily skincare!

Fantastic Product A+
Like most people I was debating between this HA serum vs the Torriden, glad I went with this one. Slightly thicker consistency than the Torriden, yet lightweight provides hydration can be added to your cushion foundation for a extra glow. Torriden did not do much my skin, felt that it just sat on my skin. This HA serum provides overall hydration, glow and can be layered well with other skincare. Another plus my teenager can also use this without any problems. A+ product in my opinion.

Good for beginners with oily skin
I have a pretty oily skin and bought this because I heard it doesn’t make your skin too greasy while still being hydrating. I found it’s not hydrating enough for me. I thought I was using it wrong but I put it on on damp skin and follow up with moisturizer, which I’ve done with other hyaluronic serums with no problem. I’m still going to finish the bottle since it still works and doesn’t break me out! Maybe this is for someone with REALLY oily skin?

Great Quality Product
This is a very high quality product, so it’s important to make sure you use correctly! I utilize when I know my skin needs the extra hydration and it works fantastic! Lightweight and it really does everything it claims. Remember: never apply on dry skin or you are wasting this product!

Hyaluronic acid that works
There’s a lot of hyaluronic acid packed into this bottle.A little spreads along way, but the benefits speak for themselve! It’s helped my skin in more ways than moisturizing.Go ahead and buy!! I’ve put a big dent in mine lol

molto leggero e acquoso come promette. Rispetto agli altri sieri all’acido ialuronico provati è molto più confortevole sulla mia pelle e si stratifica bene anche con gli altri prodotti.
