If you are searching for a serum that tackles dehydration, loss of firmness, and early signs of aging in one powerful step, SkinCeuticals HA Intensifier Multi-Glycan might just be your new favorite. This latest version builds on the success of the original HA Intensifier, now enhanced with advanced ingredients that work deeper and faster for visible results.

What It Does
At its core, this serum is designed to boost hyaluronic acid (HA) levels, helping skin look plumper, firmer, and more radiant. Hyaluronic acid is naturally found in the skin but depletes with age. The Multi-Glycan formula not only replenishes HA but also stimulates your skin to produce more of it naturally.
Key Ingredients
- 12% Proxylane™ – Supports skin structure for improved elasticity.
- 1.3% Hyaluronic Acid – Attracts and retains moisture to boost hydration.
- 2% Lactobacillus/Soybean Ferment Extract – A post-biotic that encourages skin’s glycosaminoglycan (GAG) production, contributing to visible volume.
- Licorice Root and Purple Rice Extracts – Help preserve hyaluronic acid levels and soothe the skin.
Results You Can See
According to clinical studies, users noticed smoother, more radiant skin in just 15 minutes. Over 12 weeks, the serum helped reduce fine lines by 24% and increased skin’s HA levels by 30%. These impressive stats show why it’s gaining buzz in the skincare world.

How to Use It
Apply 4 to 6 drops of the serum to your face, neck, and chest twice daily—once in the morning after your antioxidant serum, and once at night before your moisturizer. The silky, lightweight gel sinks in quickly and layers beautifully with other products.
Final Thoughts
SkinCeuticals HA Intensifier Multi-Glycan is a high-performance serum that delivers real results. With its science-backed ingredients and visible improvements in hydration and volume, it is a must-try for anyone serious about long-term skin health and glow. I instantly remember my skin feeling so comfortable and fresh after applying the serum. The HA intensifier serum has become a staple in my skincare routine, and I use it every day without exception. My skin is much softer, my pores are tighter, and the overall texture is much smoother. I love this serum under my makeup as it has a quick penetrating action.
