How the sun ages your skin

What UV does to skin

Ultraviolet (UV) radiation breaks down collagen and elastin, the proteins that keep skin firm and springy. Over the years this shows up as fine lines, rough texture, uneven colour, sun spots and loose skin. Doctors call this photoageing.

It builds up slowly, from everyday exposure as much as from beach days: the walk to the car, the drive to work, the school pick-up. That’s why two people of the same age can have very different skin, and why the backs of your hands often look older than the skin on your upper arm.

Other things that play a part

• Smoking, which reduces blood flow to the skin and speeds up collagen loss
• Poor sleep and ongoing stress, which slow the skin’s repair
• Pollution, which adds to damage at the surface
• Genetics and skin type, which you can’t change but can plan around

Can sun damage be reversed?

Damage that has already happened can’t be fully undone, but skin keeps repairing itself, and you can support that. Daily sunscreen stops further damage and gives the skin a chance to recover. A good routine with vitamin A and antioxidants helps with texture and tone. For sun spots, uneven colour and texture, in-clinic options such as laser and skin resurfacing may help some people. Like any procedure, they have recovery time and risks, which are explained at a consultation.

The habits that matter most

Wear a broad-spectrum SPF 50+ sunscreen every day, and reapply when you’re outdoors. Add a broad-brimmed hat, sunglasses and shade, especially in the middle of the day. In Australia, protect your skin whenever the UV Index is 3 or above.
