What should you know about hyaluronic acid for melasma?

Melasma causes brown or grey-brown patches, often on the face, when pigment production and distribution change. Hyaluronic acid is mainly a water-binding ingredient. A moisturising product containing it may make skin feel more comfortable and support the skin barrier, but it does not remove melasma pigment or prevent every flare.

Darkening can be influenced by sunlight, visible light, heat, hormones, irritation, and an incorrect diagnosis. New or changing facial patches may resemble other pigment conditions, so a clinician should confirm the cause before a treatment plan is chosen.

Use a gentle cleanser and moisturiser, avoid picking or harsh scrubbing, and protect exposed skin from daylight as advised by a clinician. Ask about suitable pigment-directed options, especially if you are pregnant, breastfeeding, using medicines, or prone to irritation. Patch-test new products when advised and stop a product that causes burning, swelling, or a rash. Read [Hyaluronic Acid](/materials/hyaluronic-acid/) for ingredient basics; an injection page at [Hyaluronic Acid Injection](/treatments/non-surgical-orthopedics/hyaluronic-acid-injection/) does not make injection a routine melasma treatment.

Arrange a skin assessment for rapidly changing pigmentation, a bleeding or crusting spot, a painful lesion, marked itch, or patches that do not fit the usual pattern. Seek prompt advice after a product or procedure if swelling, blistering, severe burning, spreading redness, or drainage develops.

Is this definitely melasma? Which triggers may be affecting my patches? What ingredients or procedures are suitable for my skin tone and medical history? How should I protect my skin and manage irritation?
