Photoageing
Photoageing is the skin damage that accumulates from years of ultraviolet exposure rather than from the natural ageing process. It accounts for most visible changes people associate with older-looking skin: deep wrinkles, uneven pigmentation, rough texture, and reduced elasticity.
Key points
- At the same time, melanocytes respond to repeated UV injury by producing irregular clusters of pigment, creating the flat brown spots (solar lentigines) typical of photoaged skin.
- New, changing, bleeding or persistently rough lesions need assessment for actinic keratosis or skin cancer rather than cosmetic treatment alone.
- Daily ultraviolet protection is central; a topical retinoid such as tretinoin may improve some changes but can irritate skin and is not suitable for everyone.
The listings below do not distinguish cosmetic sun damage from a precancerous or cancerous lesion; diagnosis comes before retinoid or procedural treatment.
What UV does to the skin over time
UV radiation breaks down collagen and elastin in the dermis, the structural proteins that keep skin firm and smooth. The outer layer thickens and roughens, pores appear enlarged, and fine blood vessels may become visible. These changes are distinct from intrinsic ageing and can begin appearing in a person’s thirties, or earlier with heavy, unprotected sun exposure.
Topical retinoids
It is used nightly, starting at a low concentration to allow the skin to adapt, and improvement in fine lines and tone typically becomes visible after several months of consistent use. Retinoid therapy sits within the broader skin care category of treatments at SGMeds.
When to seek urgent care
Photoageing itself is not an emergency. Arrange prompt assessment for a new or changing mole, a sore that does not heal, unexplained bleeding, or a rapidly changing pigmented patch. Stop a topical product and seek urgent help for facial swelling, breathing difficulty, blistering or a severe widespread reaction.
