Genetics gets a lot of the credit — or blame — for how skin ages, but the evidence points somewhere else almost entirely: cumulative sun exposure is responsible for the large majority of visible skin ageing, a process often referred to as photoageing.

What’s actually happening beneath the surface

UV exposure breaks down collagen and elastin — the structural proteins responsible for skin’s firmness and bounce — faster than the body can naturally replace them. Over years, this shows up as fine lines, loss of elasticity, uneven pigmentation, and a rougher overall texture, layered on top of whatever natural ageing would have occurred regardless.

Why this matters more than most people realise

The visible effects of sun damage are almost entirely preventable, which makes this one of the few genuinely high-leverage areas in skin longevity. Correction after the fact — treating pigmentation, texture, or loss of firmness once it’s visible — is almost always more involved than preventing it would have been.

What actually helps

Daily, genuinely adequate sun protection is the single most effective thing anyone can do for how their skin ages — more impactful than most treatments or products layered on top of inconsistent protection. Beyond that, antioxidant support and treatments that genuinely support collagen production can help address damage that’s already occurred, but they work best as a complement to consistent protection, not a substitute for it.

Our honest view

This is exactly why prevention sits as its own foundation in how we think about skin health at Clinic Platina, not just a footnote before talking about treatment. The most effective plan for how your skin looks in ten years is decided largely by what you do today — not by what’s corrected later.
