    Hyaluronic Acid (H.A.) Intensifer


    Hyaluronic Acid (H.A.) Intensifer

    H.A. Intensifier is awarded as Best Hydrating Serum in Her World Beauty Awards 2018. As one of the best Hyaluronic Acid serums, it amplifies the skin’s hyaluronic acid levels by 30% in 4 weeks in a clinical testing.

    H.A. Intensifier is a multi-beneficial corrective serum proven to amplify skin’s hyaluronic acid levels. This unique formulation contains a high concentration of pure hyaluronic acid, proxylane™, and botanical extracts of licorice root and purple rice to support skin’s hyaluronic acid levels and deliver surface hydration, helping improve the visible appearance of firmness, smoothness, and facial plumpness. This hyaluronic acid serum may be used as part of a home skincare regimen after dermal fillers; always consult with your physician for individual at-home advice.
    • Amplifies skin’s hyaluronic acid levels by 30%
    • Reduces the look of crow’s feet, nasolabial folds, and marionette lines for smoother, firmer skin
    • Delivers long lasting hydration to visibly improve skin’s texture
    • Unique serum gel texture creates a smooth canvas on skin
    • Paraben- and dye-free
    • Ideal for all skin types

    Visible Results

    H.A. Intensifier significantly improved the appearance of key aging markers:
    +23% improvement in plumpness
    -9% decrease in sagginess
    +11% improvement in firmness
    +13% improvement in elasticity
    +18% improvement in texture

    Pictures here are average results of our clinical study.

    Protocol: Based on a 12 week, single-center, study was conducted on 59 females, ages 42-60, 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.

    After 12 weeks


    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 aging, including decreased firmness, less facial plumpness, and rough texture.

    While hyaluronic acid is a powerful hydrator, its molecular size renders it too large for optimal skin absorption. H.A. Intensifier uniquely combines surface-hydrating hyaluronic acid with 10% proxylane and an optimal concentration of licorice and purple rice extracts to support skin’s hyaluronic acid levels.

    Best Hyaluronic Acid Serum!


    This works wonders when I pair this with the C E Ferulic and the Hydrating B5 gel. My friends have been asking me why my face has been glowing. Hands down, the best Hyaluronic Acid serum I have tried. Texture is smooth and dries quickly which is perfect for us in Singapore. Really hydrates the skin and plumps up the texture to make it firmer and smoother. Worth every cent.

    Skin is firmer and lifted


    I am LOVING this new HA serum. I believe it is beneficial to all skin types. A lot of times (if not always) the skin is unhealthy and needs nourishment. This serum is most certainly nourishing my skin and giving my skin both the feel and look of healthy, glowing, renewed skin.

    I’ve only used this serum for 3 nights now but WOW can I already tell a difference! My skin has a vibrant, youthful glow. I can tell a change in the firmness of my skin and how much healthier it looks. I am in awe.

    Glowing skin


    I love how soft my skin felt after just one use. I have sensitive skin and thr product was not drying or oily which i liked very much. The product is a bit thick but once its on the skin it applies very smoothly . After two days of using the product my skin has an even tone and a great glow which i love .

    Super Soft Skin


    I love how soft my skin felt after using this product for a couple of days. I have really sensitive skin and i love how lightweight the product feels on my skin but still feels moisturized. My skin has been glowing since using the product and i love it.

    Perfect For Firming and Creating a Healthy Glow!


    I received this product as a free sample for testing. I loved it so much I had to purchase a full-sized bottle! I use this serum in the morning and at night before I go to sleep. The elasticity for my skin has been drastic and I keep it in my fridge and use it cold! This is my pro tip for all liquid products for my skin care. I really like this product because it has given me a healthy glow in the past couple of weeks!
