What should you know about freckles after sun exposure?

Freckles are small, flat areas of increased melanin, often appearing on the face, shoulders, chest, or arms. They may be more visible in sunny months and fade when ultraviolet exposure decreases. This pattern differs from a mole, which is usually a more persistent, distinct lesion. A photograph taken in similar lighting can help you notice whether one spot is changing rather than simply comparing a summer mark with a winter mark.

Use broad-spectrum sunscreen on exposed skin and reapply as directed, especially during outdoor activities. A hat, sunglasses, shade, and clothing covering the shoulders or arms add protection. Avoid deliberate tanning and do not pick or irritate pigmented areas. If you want a cosmetic change, a dermatologist can assess the marks first and discuss options such as [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/) or [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/). These procedures require suitable diagnosis and skin-specific planning.

Arrange a dermatology assessment if a spot develops uneven borders, several colours, rapid enlargement, bleeding, crusting, persistent itching, or tenderness. Seek care for a mark that looks clearly different from your other freckles, or for a new pigmented spot that does not settle after sun exposure has reduced. Urgent review is appropriate for bleeding or rapidly changing lesions.

Ask whether the marks have the typical appearance of freckles, whether any lesion needs dermoscopic examination, and which sunscreen and cosmetic treatment fit your skin type. Ask how long to pause irritating products before a procedure and what changes should prompt a follow-up visit.
