What should you know about white spots on your skin from sun?

Sun can darken surrounding skin, making an existing pale area easier to see. Dryness, mild irritation, and some fungal surface conditions can also alter colour or texture. A clinician will consider whether the spots are smooth or scaly, whether they itch, where they occur, and whether they are spreading. Colour change alone cannot identify the cause, and it does not by itself mean skin cancer.

Notice whether the area changes after tanning fades. A sharply pale patch, loss of sensation, marked scale, or a spot that keeps enlarging deserves a closer look rather than repeated self-treatment.

Use broad-spectrum sunscreen on exposed skin, reapply as directed on the product, and choose clothing or shade during strong sunlight. Moisturise if the area is dry, and avoid scrubbing, bleaching products, or steroid creams unless prescribed. Take a clear photograph in consistent light so you can compare the outline over time.

Book a dermatology assessment if the change persists, returns, or affects several areas. Treatment depends on the diagnosis; products aimed at acne or LED Light Therapy are not appropriate for every pale patch.

Arrange prompt medical review for a rapidly changing patch, bleeding, crusting, persistent pain, a firm area, or a lesion with an irregular border. Seek urgent help for facial swelling, breathing difficulty, or a widespread rash with fever. Otherwise, a routine appointment is reasonable when the spots remain unexplained or continue to spread.

Ask whether the surface is scaly, whether a lamp or skin sample would help, which products should be stopped, and how long to monitor the colour. Mention recent sun exposure, new medicines, itching, and any family history of pigment disorders.
