Patterns of Sun Damage
Sun damage (photoageing) describes the cumulative changes to skin structure and appearance resulting from prolonged ultraviolet radiation exposure. UV radiation damages skin DNA, degrades collagen and elastin, promotes abnormal melanocyte activity, and induces chronic inflammation. Visible changes include fine lines and wrinkles, textural roughening, irregular pigmentation (solar lentigines — 'age spots'), dilated blood vessels (telangiectasia), loss of elasticity, and a leathery quality to heavily sun-exposed skin. More clinically significant are the precancerous and cancerous lesions that accumulate with sun damage: actinic keratoses (rough, scaly patches that may progress to squamous cell carcinoma), basal cell carcinoma, squamous cell carcinoma, and melanoma. Sun protection from early childhood prevents the majority of sun damage and reduces skin cancer risk.

The Evidence
Evidence context
What research says about sun damage, photoageing, and the approaches used to prevent and manage it.
Overall pictureStrong evidence base
Prevention is well-supported; some reversal is possible
Sun damage has one of the strongest evidence bases in dermatology. Sunscreen and UV avoidance reliably prevent photoageing and reduce skin cancer risk. Some visible changes can be partially reversed with established topical treatments.
When to seek prompt medical reviewSome skin changes linked to sun damage require urgent professional assessment.
Seek prompt care for any lesion that changes shape, colour, or size rapidly, a wound that does not heal, or a spreading rash accompanied by fever. Signs of skin infection — increasing redness, warmth, swelling, or discharge — also warrant timely review. Do not self-manage these presentations.
How strong is the evidence?Prevention and some reversal of sun damage are backed by robust research.
Broad-spectrum sunscreen has very strong evidence for reducing photoageing and lowering skin cancer risk. Topical retinoids have strong evidence for partially reversing visible photoageing changes. Actinic keratoses respond well to cryotherapy and topical agents, with consistent clinical trial support across all three areas.
What happens to skin with UV exposureUV radiation causes cumulative structural and cellular changes over time.
UV radiation damages skin DNA, breaks down collagen and elastin, and drives abnormal pigment cell activity. Over years, this produces wrinkles, uneven pigmentation, loss of firmness, and textural changes. More significantly, it raises the risk of precancerous lesions and skin cancers including melanoma, basal cell, and squamous cell carcinoma.
Approaches used for sun damageA range of preventive, topical, and procedural options exist across care settings.
Daily broad-spectrum sunscreen and protective clothing remain the most effective preventive tools. Topical retinoids and vitamin C serums are commonly used for visible photoageing. Dermatologists may offer chemical peels, laser resurfacing, or targeted treatments for actinic keratoses. Complementary approaches may support skin health but should not replace professional assessment of lesions.
When professional assessment mattersA dermatologist or GP should assess any concerning skin lesion.
Anyone with a history of significant sun exposure, multiple moles, or changing skin lesions should have periodic professional skin checks. Actinic keratoses and other precancerous changes require professional assessment and management. Self-monitoring is useful, but it is not a substitute for professional evaluation of suspicious lesions.
What the evidence does not coverSome popular skin care claims around sun damage go beyond what research supports.
Many topical products marketed for photoageing reversal have limited or no robust clinical evidence. Natural oils, antioxidant supplements, and some complementary approaches may offer supportive benefits, but evidence is inconsistent. Inflated outcome claims are common in this category — look for peer-reviewed evidence before investing in unproven products.
