    Need to Know

    Frequently Asked Questions

    Where does this serum fit in my routine?
    Apply it as the very first step after cleansing, before your other serums and moisturizer, using one to two pumps morning and evening. Layering it first lets the hyaluronic acid draw moisture into freshly cleansed skin so everything you apply afterward seals it in.
    What makes this different from a regular hyaluronic acid serum?
    It uses multiple molecular weights of hyaluronic acid to hydrate at different depths, and it's built on Alastin's TriHex Technology. Beyond delivering immediate moisture, it's designed to help support your skin's own hyaluronic acid levels over time.
    Should I apply it to damp or dry skin?
    Hyaluronic acid serums perform beautifully on slightly damp skin because there's more surface moisture for them to bind. If you apply it to dry skin, just be sure to follow with a moisturizer to lock the hydration in.
    Is this a good choice for dry or dehydrated skin?
    Yes, it's especially well suited to dry, dehydrated, or sensitive skin. It floods the skin with lightweight hydration and helps reinforce the moisture barrier, leaving skin looking plumper and more radiant.
    Can I use it alongside actives like retinol or vitamin C?
    It pairs very well with actives. Applying a hydrating serum first can help buffer the skin and improve comfort when you layer stronger treatments like retinol on top.
