    H.A. Intensifier


    H.A. Intensifier

    A multi-functional corrective serum proven to improve skin plumpness, firmness and texture by amplifying skin’s Hyaluronic Acid content.

    Formulated with a high concentration of Hyaluronic Acid (HA), Proxylane™ and Botanical Extracts of Purple Rice and Licorice, H.A. Intensifier is a corrective serum clinically proven to restore  plumpness, elasticity and firmness in the skin by helping to support skin’s Hyaluronic Acid levels. This new serum effectively delivers surface hydration to the skin, whilst improving the appearance of the crow’s feet area, nasolabial folds and marionette lines for a more refined complexion.
    • Amplifies skin’s hyaluronic acid levels by 30%*
    • Reduces the look of the crow’s feet area, nasolabial folds and marionette lines for smoother, firmer skin
    • Delivers long lasting hydration to visibly improve skin’s texture
    • Paraben- and dye-free
    • Ideal for all skin types

    *Total Hyaluronic Acid content evaluated with ELISA method on skin biopsies.

    Clinical study

    In a 12-week study, H.A. Intensifier significantly improved the appearance of key ageing markers:
    +23% improvement in plumpness
    +18% improvement in texture
    +13% improvement in elasticity
    +11% improvement in firmness
    +9% improvement in sagginess

    Protocol: A 12-week, single-center, clinical study was conducted on 59 females, ages 40-60, with mild to moderate facial sagging and loss of firmness, rough skin texture, nasolabial fold wrinkles, marionette wrinkles, and presence of fine lines/wrinkles in the crow’s feet area. H.A. Intensifier was used twice daily in conjunction with Gentle Cleanser and a sunscreen. Efficacy and tolerability evaluations were conducted at baseline and at weeks 4, 8, and 12.



    Hyaluronic Acid is a powerful natural humectant which helps regulate moisture levels in skin. This essential molecule however, has a short lifecycle in skin, with 30%-50% degrading every 24 hours. With age, the skin experiences a gradual decline in Hyaluronic Acid levels. Production starts to decrease in the 20s and accelerates in the 40s. The combination of decline and this rapid degradation of Hyaluronic Acid contribute to signs of ageing, including decreased firmness, less facial plumpness and rough texture.


    Once or twice daily, apply 4-6 drops to the palm of the hand and dab onto forehead, cheeks, chin and neck. If using in the morning, apply after a SkinCeuticals Vitamin C antioxidant serum and before a SkinCeuticals sunscreen. If using with a Retinol at night, apply after Retinol application.
