should i wear spf daily? 

At Dermalogica, we’re big advocates of the daily use of sunscreen, in fact, we recommend everyone include SPF30 or SPF50 in their daily regimen, no matter your skin type, skin tone or age.  

the impact of uv rays on the skin 

When it comes to causes of skin damage, premature ageing and uneven skin tone, exposure to ultraviolet radiation is at the top of the list. Rather than thinking about protecting your skin from the sun during the summer months or on beach holidays, consider the fact that we are exposed to harmful UV rays all year round – yes, even in the winter and when indoors! 

UVA and UVB rays are present during daylight hours, and both penetrate the skin triggering damage. UVB rays are often nicknamed the ‘burning ray’ they are at their strongest in the summer months and when the sun is highest in the sky, typically between 11:00 and 3:00. This ray is short and intense, meaning you feel its effects on your skin. You can often feel your skin burning! 

UVA is a longer ray, that penetrates deeper into the skin but without you noticing. UVA rays are known as the ‘ageing ray’ as they cause deep damage to skin cells and structural proteins like collagen. UVA rays are present at the same strength from dusk till dawn year-round and can penetrate windows and glass. 

The bottom line is that exposure to these rays’ cause damage to the skin. Whilst your skin can repair some of this damage, the damage accumulates over the years resulting in premature ageing. Lines, wrinkles, and dark spots become evident and worst-case scenario; this damage may lead to skin cancer development.

6 tips to prevent skin damage from the sun and skin cancer risk 

Up to 90% of skin cancers are preventable by adopting simple sun safe strategies. Applying a Broad-Spectrum sunscreen with a high or very high SPF rating (SPF30 to SPF50) on a daily basis will keep skin protected from both UVA and UVB rays. Adopting a daily habit of SPF application is also the best way to preserve your skin’s youth. 

  1. Apply SPF generously to get the level of protection on the label. Around a teaspoon for the face and shot glass for the body 
  1. Reapply every 2 hours when exposed for longer periods and after swimming/sweating 
  1. Seek shade and protect vulnerable areas by adding a hat and sunglasses 
  1. Don’t forget to apply SPF to your ears and the back of your neck! 
  1. Remember UV rays can penetrate glass. Consider SPF when sitting in the car or by a window 
  1. UV rays reflect off light surfaces such as snow, sand and water intensifying the exposure
