What should you know about hyaluronic acid at night?

A topical hyaluronic acid product sits on the skin and helps reduce the feeling of dryness by attracting water near the surface. Applying it to clean, slightly damp skin and following with a suitable moisturiser may make the routine more comfortable. An injection places a different formulation into tissue and has separate aftercare. A night-time application cannot replace assessment of persistent pain, swelling, a rash, or another changing skin problem.

Cleanse gently, apply the product according to its label, and stop if burning or a new rash develops. Avoid layering several irritating active products when you are trying a new formulation. If you have recently had an injection, use only the products and cleansing method approved by the treating clinician; avoid rubbing, pressure, heat, or strenuous activity when instructed. Tell the clinician about eczema, allergies, medicines, and previous reactions before any injectable treatment.

Seek advice for persistent burning, spreading redness, blistering, or swelling after a topical product. After an injection, urgent assessment is needed for severe pain, rapidly worsening swelling, pale or dark skin, vision changes, facial weakness, breathing trouble, or widespread hives. Do not apply extra products over a concerning reaction while waiting for advice.

Ask whether your concern calls for a topical product or an injection, which ingredients to avoid around treatment, and how to wash and sleep comfortably afterward.
