H.A. Intensifier Multi Glycan

SkinCeuticals H.A. Intensifier Multi-Glycan is a next-generation hyaluronic acid volumizing serum that goes beyond surface hydration to visibly plump, firm, and define the skin from within. Proven to amplify the skin’s own hyaluronic acid levels by 30%, this advanced formula combines 1.3% pure hyaluronic acid, 12% Proxylane™, and a new post-biotic Lactobacillus ferment to increase glycosaminoglycans — the structural molecules responsible for skin volume and moisture retention — preserving their levels in the skin’s uppermost layers. Instantly, skin is plumped and rehydrated for up to 24 hours; over time, elasticity and firmness are renewed and facial contours become more visibly defined.

The evolution of the original H.A. Intensifier, the Multi-Glycan formula introduces an elevated 12% Proxylane™ concentration and the addition of Lactobacillus Extract — a post-biotic ferment that further supports glycosaminoglycan production for a more comprehensive, multi-dimensional approach to skin volumization. Paraben-free, fragrance-free, and dye-free, it is suitable for all skin types and can be used as part of a home skincare routine after dermal filler treatments — always consult with your physician for individual at-home advice. Available in a 15ml travel size and full-size 30ml.

Skin Types

Suitable for all skin types including dry, normal, oily, combination, sensitive, and dehydrated. Particularly beneficial for those experiencing visible signs of aging associated with declining hyaluronic acid levels, including loss of facial volume, reduced firmness, and rough or dull skin texture.

Skin Concerns

Key Ingredients

• 12% Proxylane™ — A patented active derived from beech tree wood that supports the skin’s hyaluronic acid levels by stimulating the production of glycosaminoglycans — the structural molecules responsible for maintaining skin volume, firmness, and hydration. At 12%, the Multi-Glycan formula delivers an elevated concentration compared to the original H.A. Intensifier, providing enhanced support for skin structure and volume over time.
• 2.0% Lactobacillus Extract (Post-Biotic Ferment) — A new addition to the Multi-Glycan formula, this post-biotic ferment derived from Lactobacillus bacteria further increases glycosaminoglycans such as hyaluronic acid in the skin’s uppermost layers. By supporting the skin’s own production of these essential structural molecules, Lactobacillus Extract contributes to the multi-dimensional volumizing and plumping effect that distinguishes this next-generation formula.
• 2.0% Licorice Root Extract (Dipotassium Glycyrrhizate) + 0.2% Purple Rice Extract — A synergistic botanical duo that works together to help preserve hyaluronic acid content within the skin. Licorice root extract provides anti-inflammatory and antioxidant support, while purple rice extract — rich in anthocyanins — helps protect hyaluronic acid from degradation, extending its presence and effectiveness in the skin.
• 1.3% Hyaluronic Acid — A powerful natural humectant that attracts and retains water molecules at the skin’s surface, delivering immediate plumping and long-lasting hydration. Works in concert with Proxylane™ and Lactobacillus Extract for a comprehensive, multi-level approach to skin hydration and volumization.

How to Use

Apply 4–6 drops to the palm of the hand and dab onto the forehead, cheeks, chin, and neck once or twice daily. Blend the serum gently into skin until fully absorbed. In the morning, apply after a SkinCeuticals vitamin C antioxidant serum and before a SkinCeuticals broad-spectrum sunscreen. In the evening, apply before moisturizer as part of your complete anti-aging regimen. For post-filler home care, follow your physician’s specific protocol and timing recommendations.
