SkinCeuticals H.A. Intensifier Multi-Glycan

$170.00

An advanced hyaluronic acid serum formulated to visibly plump, smooth, and enhance skin firmness. SkinCeuticals H.A. Intensifier Multi-Glycan boosts hydration while improving the look of fine lines and facial volume.

This is not your basic HA serum.

H.A. Intensifier Multi-Glycan is about structure and volume — not just surface hydration. We love it for clients noticing early laxity, dehydration lines, or that slight loss of bounce. It gives that subtle, healthy fullness that makes skin look rested and resilient.

If your skin feels thin or depleted, this is your hydration upgrade.

As we age, natural hyaluronic acid levels decline — leading to dehydration, fine lines, and a loss of facial fullness. SkinCeuticals H.A. Intensifier Multi-Glycan is a next-generation hyaluronic acid serum designed to amplify skin’s hydration while supporting visible plumpness and contour definition.

This advanced formula combines multi-weight hyaluronic acid with Proxylane™ and a post-biotic ferment to help enhance glycan levels in the skin. The result? Improved skin density, smoother texture, and visibly reduced fine lines.

Lightweight yet deeply hydrating, this serum layers seamlessly into any routine and pairs beautifully with vitamin C, peptides, and retinol. With consistent use, skin appears firmer, more supple, and noticeably refreshed.

• Use morning and evening
• Apply 4–6 drops to clean skin
• Follow with moisturizer
• Finish with SPF in the morning

Pro Tip: Apply to slightly damp skin to maximize hydration benefits.

Frequently Asked Questions

H.A. Intensifier Multi-Glycan is an advanced topical serum used to boost skin hydration and visibly plump, smooth, and improve the look of fine lines and facial volume. It combines hyaluronic acid with a multi-glycan approach to attract and retain moisture at multiple skin depths, which delivers immediate plumping and supports skin firmness over time. Because it targets hydration and volume loss rather than pigment or acne, it is most useful for people concerned with early to moderate signs of aging, dehydration lines, and loss of facial fullness. It is not a replacement for injectable volume treatments; instead it complements professional procedures and daily medical grade care when used consistently as part of a clinical-strength regimen.
H.A. Intensifier Multi-Glycan is suitable for most skin types, including normal, dry, combination, oily, and sensitive skin. Hyaluronic acid is a lightweight humectant that increases hydration without adding oil, so it plumps and smooths skin without feeling heavy or greasy. The formulation is intended for clinical use, making it appropriate for people seeking professional-grade hydration and anti-aging benefits across a range of skin conditions. Those with active eczema, rosacea flares, or severe reactive skin should patch test first and consult a skincare professional because individual sensitivity can vary.
Yes, many people with sensitive skin can use H.A. Intensifier Multi-Glycan because it focuses on hydration rather than irritating exfoliants or harsh actives. Hyaluronic acid and glycan-supporting ingredients attract and hold moisture, which often soothes tight or reactive skin and improves barrier function. Clinically minded users with sensitivity benefit most when they introduce the serum gradually and apply it on damp skin followed by a gentle moisturizer. If you have a history of severe reactions, active dermatitis, or are using prescription topical treatments, patch testing or professional guidance is recommended to confirm tolerance.
Use H.A. Intensifier Multi-Glycan after cleansing and any water-based toners and before heavier moisturizers or oils. Apply a few drops to slightly damp skin to maximize the humectant effect of hyaluronic acid, then follow with a moisturizer to lock in hydration and a broad-spectrum sunscreen during the day. Typical use is once or twice daily depending on your skin’s needs; consistent application delivers both immediate plumping and longer-term improvement in texture and firmness. If you are combining it with prescription retinoids or professional procedures, check with your clinician to time use for optimal tolerance and results.
You can expect immediate improvements in hydration and a visible plumping effect within hours of application, while more noticeable changes in fine lines, texture, and facial volume generally emerge with regular use over several weeks. The immediate effect comes from hyaluronic acid drawing moisture into the skin, whereas the multi-glycan approach supports dermal structure and firmness over time. Most users report progressive improvement over four to eight weeks, but results vary by skin condition, age, and consistency of use. For faster or more dramatic changes, combine this serum with in-office treatments under professional guidance.
