A hyaluronic acid volumizing and plumping serum

HA Intensifier Multi-Glycan is a multi-dimensional, lightweight serum designed to volumize, plump, and hydrate the skin while visibly redefining facial contours and filling fine lines. Suitable for all skin types—including normal, oily, dry, combination, and sensitive—this advanced formula helps stimulate glycans responsible for maintaining skin volume.

Clinically proven to increase skin’s own hyaluronic acid (HA) levels by 30%, this next-generation serum combines 1.3% pure hyaluronic acid, 12% Proxylane™, and a new post-biotic ferment to boost glycosaminoglycan (GAG) production and preserve HA levels in the skin’s uppermost layers. Upon application, skin is instantly rehydrated and visibly plumped for up to 24 hours. With continued use, facial contours become more defined, elasticity and firmness are visibly improved, and skin appears more youthful and radiant.

This corrective HA serum is paraben-free, fragrance-free, dye-free, and suitable for use as part of a home skincare routine following dermal filler treatments—though always consult your physician for personalized advice.

The Science Behind HA Intensifier Multi-Glycan

Glycosaminoglycans and Skin Volume

Glycosaminoglycans (GAGs) play a vital role in the skin’s structural support and hydration. Hyaluronic acid, the most well-known glycan, accounts for approximately 50% of total GAGs in the skin and is essential for moisture retention. The remaining 50% contributes to skin strength and structure. HA Intensifier Multi-Glycan supports both moisture and skin resilience by enhancing glycan levels through a unique combination of ingredients.

How to Use

1. Prep + Dispense
   Once or twice daily, dispense 4–6 drops into the palm of your hand. Dab onto the forehead, cheeks, chin, and neck.
2. Apply + Complete
   Blend the serum into the skin. If using in the morning, apply after your SkinCeuticals vitamin C antioxidant serum and before sunscreen.

Key Ingredients

• 12% Proxylane™
  A sugar-derived molecule (synthesized from xylose found in birch and beech wood) that strengthens the extracellular matrix and improves skin elasticity and firmness. This super-hydrating ingredient helps restore volume, reduce wrinkles, and maintain moisture levels. It’s also considered environmentally friendly.
• 1.3% Hyaluronic Acid
  A natural moisture-binding molecule that draws water to the skin’s surface from both the air and deeper skin layers. It replenishes hydration, reduces fine lines and wrinkles, and supports healing while improving flexibility, smoothness, and overall skin health.
• 2.0% Lactobacillus/Soybean Ferment Extract
  A post-biotic ferment that helps increase glycosaminoglycan levels and visibly improve facial volume.
• 2.0% Licorice Root Extract (Dipotassium Glycyrrhizate) + 0.2% Purple Rice Extract
  A synergistic antioxidant duo that helps prevent the degradation of hyaluronic acid. These ingredients also give the formula its signature purple hue.
