What should you know about lip melasma?

Melasma develops when pigment-producing cells become more active in a local area. On the lips, the visible change may sit on the skin above the upper lip, at the border, or on nearby facial skin rather than on the wet inner lip. Sun and visible light can deepen the colour, while heat, hormonal changes, irritation, and some medicines may influence it. The pattern is usually flat rather than raised, and it is not typically scaly or ulcerated.

A clinician may examine the distribution, surface, timing, and any products or treatments touching the area. Similar-looking dark patches can have other causes, so a new, changing, itchy, bleeding, or one-sided mark should not be self-labelled. Read about [Melasma](/conditions/melasma/) and [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) for broader context.

Use broad-spectrum sun protection on the surrounding skin every day, reapply when outdoors, and add shade such as a hat. Choose a bland cleanser and moisturiser; avoid rubbing, waxing irritation, fragranced products, and unplanned bleaching mixtures around the mouth. Take photographs in similar lighting if you want to track gradual changes.

A dermatologist can discuss prescription creams or procedures according to your skin tone, pregnancy or breastfeeding status, medicines, and sensitivity. Options may include [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), microneedling, or laser toning, but irritation can make pigmentation darker, so the choice and settings matter.

Arrange a medical assessment if the mark is new and rapidly changing, becomes raised, crusted, painful, itchy, or bleeds, or differs clearly from the pigmentation around it. Seek prompt advice for swelling, blistering, or a severe reaction after a product or procedure. Otherwise, book a routine dermatology visit when the colour persists, affects your confidence, or has not improved with gentle protection.

Ask whether the pigment pattern fits melasma, whether a medicine or product may be contributing, and which sunscreen and active ingredients are suitable for the skin around your mouth. Ask how long to try a plan, what irritation looks like, and when a procedure should be avoided.
