What should you know about melasma on side of face?

The patches are usually flat and brown or grey-brown, with edges that may blend into nearby skin. They can occur on one side or both sides and may become more noticeable after light or heat exposure. A clinician looks at symmetry, texture and timing because dark patches have several possible causes. Melasma affects colour rather than creating a lump or open sore.

Rubbing from masks, helmets, phones or hair products can irritate the cheek and temple area. Irritation can leave additional pigment, so avoid trying to scrub the colour away.

Apply sunscreen to the entire side of the face each morning, including areas near the hairline and ears, and use shade or a wide-brimmed hat outdoors. Keep cleansing mild and moisturise regularly. If a product stings, stop it and let the skin settle. A dermatologist can select topical treatment according to your skin type, medical history and pregnancy or breastfeeding status.

For persistent pigment, options may include a chemical peel, microneedling, laser toning or another skin-brightening approach. These should be performed by an experienced clinician with a plan for preventing irritation. Read about [Uneven Skin Tone](/symptoms/uneven-skin-tone/) and [Laser Toning](/treatments/laser-and-energy/laser-toning/).

Book a dermatology review for a new or uncertain patch, especially if it changes quickly, becomes raised, bleeds, crusts, hurts or does not resemble the other areas. Get prompt advice for blistering, severe swelling or ongoing burning after a product or procedure. A flat patch may be suitable for a routine appointment, but a changing spot should not be labelled melasma without examination.

Ask what features support melasma, whether another cause should be ruled out, and which sunscreen and topical ingredients fit your skin. Discuss whether a procedure is appropriate, how to reduce irritation around the cheek, and what improvement or worsening should prompt a follow-up.
