FAQs

WHEN TO USE Apply Hyaluronic Acid Serum after cleansing, on damp skin. Wait 30-60 seconds, then follow with other treatments.

CAN IT BE USED WITH OTHER PRODUCTS? Yes, it works with everything (including actives like Retinol & AHAs) and enhances the effectiveness of other products.

DO I NEED A MOISTURISER? Hydrators (like Hyaluronic Acid) add water to the skin, while moisturizers lock it in. You may need both, depending on your skin type.

WHO IS IT FOR? All skin types, especially dry or dehydrated skin, and mature skin needing a hydration boost.

IS IT AN AHA? No, it hydrates, not exfoliates.

A gentle, hydrating and anti aging serum
I have extremely fussy skin and I have trouble finding products that I can tolerate long term. This serum is great on my skin right after I cleanse and pat it damp, and before applying moisturizer. It also contains Matrixyl which I only recently realized, and I think it should be mentioned in the name because it's a big deal for anti-aging concerns. It has a slightly tacky texture on its own but it sits nicely under my skin cream. I wear a tinted sunscreen on top and I haven't noticed any pilling.
