Sun Damage Diagnosis and Treatment in London

Sun damage refers to the harmful effects of ultraviolet (UV) radiation on the skin, leading to premature ageing, pigmentation changes, dryness, and an increased risk of skin cancer. Over time, repeated sun exposure breaks down collagen and damages DNA within skin cells. At Skinhorizon Clinic London, we offer advanced treatments to repair sun-damaged skin and protect long-term skin health.

Understanding sun damage

Sun damage, also known as photoageing, occurs when ultraviolet (UV) radiation penetrates the skin, causing structural and genetic changes. While a tan may appear attractive, it is a sign of skin injury. Repeated exposure leads to visible and invisible damage, including an increased risk of skin cancer.

Types of sun damage

Sunburn: Red, painful, sometimes blistering skin after excessive UV exposure.
Photoageing: Wrinkles, leathery skin, and sagging caused by collagen breakdown.
Pigmentation changes: Freckles, age spots, and uneven skin tone.
Actinic keratoses: Precancerous scaly patches that may progress to squamous cell carcinoma.
Skin cancers: Basal cell carcinoma, squamous cell carcinoma, and melanoma are strongly linked to UV damage.

Symptoms of sun damage

Fine lines and deep wrinkles
Dry, rough or leathery texture
Uneven pigmentation or sunspots
Broken capillaries and redness
Loose or sagging skin
Precancerous or cancerous lesions

Diagnosis of Sun Damage

Diagnosis is made through a dermatologist’s examination, dermoscopy, and advanced skin imaging tools. Suspicious lesions may require a biopsy to rule out malignancy.

Treatment options for Sun Damage

Topical treatments: Retinoids, antioxidants, and pigment-lightening agents like hydroquinone.
Chemical peels: Improve pigmentation, texture, and fine lines.
Laser resurfacing: Targets pigmentation, stimulates collagen, and improves texture.
Photodynamic therapy: Used for precancerous lesions such as actinic keratoses.
Microneedling and skin boosters: Promote skin repair and hydration.
Daily sun protection: Broad-spectrum SPF is essential for prevention and maintenance.

Prevention strategies

Apply broad-spectrum sunscreen (SPF 30+) daily, reapplying every 2 hours outdoors
Wear hats, sunglasses, and protective clothing
Avoid tanning beds and peak sunlight (11am–3pm)
Use antioxidant-rich skincare to support skin repair

Sun Damage FAQs

Can sun damage be reversed?

While some changes are permanent, many effects such as pigmentation and fine lines can be improved with dermatological treatments.

Does sunscreen really prevent ageing?

Yes. Daily use of broad-spectrum sunscreen is the most effective anti-ageing skincare measure.

Are freckles a sign of sun damage?

Yes. Freckles are usually triggered by sun exposure and indicate underlying sun sensitivity and damage.

Can I still get sun damage on cloudy days?

Yes. Up to 80% of UV rays penetrate clouds, meaning sun protection is still necessary.

Does sun damage always cause skin cancer?

No. Not all sun damage leads to cancer, but cumulative UV exposure increases the risk significantly.
