Spots caused by sun exposure

Ultraviolet exposure can stimulate pigment production, creating tan or brown flat marks on exposed areas such as the face, shoulders, chest, and hands. Existing marks after acne, eczema, or injury may also darken in sunlight. Freckles can become more visible with exposure, while rough or scaly areas may represent a different type of sun-related change. A photograph cannot reliably distinguish every cause, so texture, border, colour, and change over time are useful details for a skin examination.

Use broad-spectrum sun protection on exposed skin, reapply as directed on the product, and add shade, clothing, and a hat. Avoid tanning devices. Do not use bleaching products, strong acids, or home freezing treatments on an uncertain mark. A dermatologist may consider prescription creams, peels, or light-based procedures after confirming the diagnosis and your risk of pigment changes. Treating the cause and protecting the skin help reduce recurrence.

Book a skin assessment if a spot is new and persistent, changes in size, shape, colour, or texture, bleeds, crusts, or fails to heal. Seek prompt review for a rapidly changing or markedly different mark. Do not assume every brown spot is harmless simply because it is on sun-exposed skin.

Does this mark look like sun-related pigmentation or something else? Do I need a closer examination? Which treatment is suitable for my skin tone, and how can I limit pigment changes afterward?
