What should you know about melasma under chin?

Melasma can affect areas exposed to light and may be more noticeable as symmetrical tan or brown patches. The underside of the chin is also exposed to rubbing, mask contact, cosmetics and hair-removal products. A rash or tiny injuries can leave pigment behind after the original irritation has faded.

During an assessment, describe whether the area is smooth or scaly, how quickly it appeared, and whether it darkens after sun or heat exposure. A new, one-sided or textured mark should not be labelled melasma from appearance alone.

Keep the routine simple: wash gently, moisturise, and protect the face and neck from daylight with clothing or a suitable broad-spectrum sunscreen. Use shade when possible. Stop any product that burns, peels or causes a rash, and avoid picking or vigorous exfoliation.

A dermatologist can decide whether a topical pigment treatment is appropriate and whether the skin is calm enough for Chemical Peel, Microneedling, Skin Brightening Treatment or Laser Toning. Hair-removal technique and treatment timing may need adjustment if repeated irritation is maintaining the colour.

Arrange an assessment for a patch that persists, expands, becomes itchy or scaly, or follows repeated burning from a product. Seek prompt review if it bleeds, crusts, ulcerates, forms a lump or changes quickly. Cosmetic procedures should wait until a concerning mark has been identified.

Ask whether the colour and distribution support melasma, whether post-inflammatory pigmentation is more likely, and how to protect the chin during hair removal. Discuss suitable active ingredients, expected skin reactions, and whether a procedure could trigger more pigment in your skin type.
