Sun and wrinkles: what to know

Ultraviolet radiation reaches skin cells and contributes to collagen breakdown, reduced elasticity, uneven colour, and rougher texture. Repeated facial movement also creates expression lines, so sunlight and movement can work together. Sun-damaged skin may show fine lines on areas that receive regular exposure, including the face, neck, chest, and hands. Wrinkles are common, but a sudden change in one area deserves a closer look.

Use shade, hats, sunglasses, protective clothing, and sunscreen on exposed skin. Reapply according to the product directions, especially after sweating or swimming. Moisturiser can soften the feel of rough skin, while a dermatologist can discuss options suited to your concerns and skin type. Botulinum toxin injection may reduce selected movement-related lines; dermal fillers may restore support in particular areas. These treatments address different features and require an in-person assessment.

Book a skin assessment if a mark changes quickly, bleeds, crusts, becomes persistently sore, or looks different from nearby sun-exposed skin. Seek urgent help for swelling around the eyes with visual symptoms or a severe reaction after a product. A clinician can separate ordinary lines from sun-damaged skin or another lesion.

Which lines are mainly caused by movement, and which reflect sun damage? What protection should I use for my skin tone and routine? Which treatment fits the area, and what changes should make me return for review?
