SkinCeuticals H.A. Intensifier Multi-Glycan Serum

The SkinCeuticals H.A. Intensifier Multi-Glycan Serum is a concentrated hydrator designed to increase skin moisture and improve the appearance of fine lines and texture. It’s suitable for people with dry or dehydrated skin, those noticing early signs of ageing, and anyone who wants a lightweight, non-greasy boost of hydration that layers under moisturiser and makeup.

What it is

How to use

• Mornings: After cleansing, apply 4–5 drops to slightly damp skin. Pat gently over face and neck, then follow with your moisturiser and an SPF in the morning to protect the skin barrier. SPF
• Evenings: Apply 4–5 drops after cleansing and before your night moisturiser or other targeted treatments.
• Use twice daily for consistent results. Avoid rubbing; patting helps product absorption.

Why it works

• Hyaluronic acid — attracts and holds moisture to give a plumper, smoother look.
• Proxylane® — supports structural components of the skin that contribute to fullness and resilience.
• Multi-glycan complex (including rice and plant extracts) — helps support the skin’s natural hydration network and texture.
• Soybean ferment — helps support the skin barrier after environmental stress.

What to expect

• Immediate: skin feels more hydrated and smoother after the first application.
• Short term: improved texture and a fresher appearance within 1–2 weeks of regular use.
• With continued use: ongoing improvement in plumpness and reduced appearance of fine lines over several weeks.

Good to know

• Patch-test on inner forearm before introducing to your full routine if you have very reactive skin.
• If you are pregnant, breastfeeding or using prescription topical treatments, consult your healthcare professional before adding new actives.
• Stop use and seek advice if persistent irritation occurs.
