sun protection

What is the sun doing to your skin?

Finally summer seems to be here, and all of Britain is celebrating by exposing ourselves to the suns rays at every available opportunity. But while a bit of sunshine may make us feel good, this does come at a cost. We should by now all be aware of the dangers of skin cancer, but what about the ageing effects of the sun?


UV radiation – the rays that come from the sun – can be broken down into three categories: UVA, UVB and UVC. UVC rays are absorbed by the Ozone layer and so don’t affect our skin, but UVA and UVB can have some worrying effects, including:

Collagen breakdown

UV radiation causes the collagen fibres in our skin to break down at a higher rate than they would as part of the normal ageing process. Whilst the collagen fibres are breaking down, abnormal elastin fibres are being created, and as this process repeats over time, as part of the skin’s natural rebuilding process, wrinkles are created.

Free radical creation

Sunlight is one of the biggest culprits when it comes to free radical creation. Free radicals are unstable oxygen molecues that cause wrinkles by activating the cells that break down collagen. As a cosmetic doctor in London, Dr Joney de Souza spends much of his professional time trying to stimulate the production of collagen using treatments like medical microneedling, or simulate its appearance with fillers, so if you can avoid exposing yourself to its premature breakdown in the first place, you could delay the need for aesthetic treatment.

Act now to avoid further damage

If you have been guilty of sun worshipping, it is time to call it a day if you want to avoid premature ageing. Use a high factor sunscreen (SPF 30+) when you do go out into the sun – or indeed in any weather, as the sun’s rays can damage our skin even on a rainy day – and avoid spending prolonged periods in bright sunlight.

If you’ve already spent a lot of time in the sun and feel that the damage is starting to show, come to Dr Joney de Souza Aesthetic Clinic in London to find out how we can help erase some of those telltale signs. Laser skin rejuvenation, Botox, fillers and chemical peels can all help to reduce the appearance of sun damage and help you achieve younger-looking skin.
