    Small but very long lasting!

    This small bottle lasted me a few months! It's super hydrating I loved using it before my moisturizer. Perfect for people who struggle with dryness and dehydration, especially while using retinol & retinoid products that can be drying!

    Best Hyaluronic acid

    This is the best Hyaluronic acid ever. I have used quite a few different brands, one of the very famous ones gets so much pilled on my skin. Been loving this one as no issues and skin feels so plump and soft. Definitely worth the money.
