FAQs

WHEN TO USE HYALURONIC ACID SERUM Apply morning and evening after cleansing on damp skin.

HOW TO USE HYALURONIC ACID SERUM On cleansed, damp skin, apply 2-3 drops and gently pat in. Apply preferred serums or treatments. Always follow with moisturizer to lock in hydration. Can be used twice daily.

WHY FIRST AFTER CLEANSING? This serum absorbs best on damp skin and creates a hydration barrier for products that follow. It also soothes skin and balances pH.

SHOULD I HYDRATE BEFORE A TONER? Yes, it helps the toner and other products absorb better by working deep beneath the skin’s surface.

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

CAN YOU USE HYALURONIC ACID WITH VITAMIN C SERUM? Yes! Apply Hyaluronic Acid first on damp skin, wait 30-60 seconds, then apply vitamin C serum. HA actually helps vitamin C absorb better and reduces potential irritation.

DO I NEED A MOISTURIZER? 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.

WHAT % OF HYAURONIC ACID IS THERE %? 2% Multi-Molecular Hyaluronic Acid.

Forever a staple
No matter how many hydrating serums I try, I will always love this simple staple. I find myself adding it to my routine even when there is plenty of hydration going on, because I know it will only boost the efficacy and duration of whatever else I use.
