Pigmentation

Sun Tan & Persistent Darkening

Tanning is a protective pigment response; persistent patchiness may include additional pigmentation concerns.

In plain language

What this term means.

A tan develops when ultraviolet exposure stimulates melanin production. Repeated exposure also contributes to uneven pigment and premature skin ageing.

Frequently asked

Questions to take into consultation.

A photograph can document appearance but may not show texture, depth, scalp findings or warning signs. A diagnosis and personalised plan may require history and in-person examination.

Not usually. The appropriate pathway depends on the cause, severity, skin or hair characteristics, previous treatment, medical suitability and the result you hope to achieve.
