Why you should wear sunscreen in winter

Why you should wear sunscreen in winter:

Don’t think you can skip sunscreen in winter.

If you’re thinking of editing out applying sunscreen from your makeup routine, think again. Although it may seem counter-intuitive to apply sunscreen when the temperature is dipping, don’t be mislead by the weak, wintery sun. Although the sun may not seem to be firing on all his cylinders, the sun rays are still potent with UVA rays (Ultra Violet A) that penetrate into the dermis and cause damage by altering the skin’s cellular structure. 

 Despite the fact that most sunscreens protect against UVB rays (Ultra Violet B) that target the epidermis, new research says that scientists have found protection against UVA too. University of Bath scientists in collaboration with scientists at King’s College London have developed a compound called ‘mitoiron claw’ that offers protection inside the cells which is where UVA rays cause the most damage. The scientists hope that this compound will be added to sunscreens in the next three to four years. Till then stay calm and use sunscreen. Dr Sujata Chandrapur gives us some pointers. 

Above 26: Choose a sunscreen that has SPF26 and above, which will help reflect UVA rays and offer protection against UVB rays.

How long: If you’re going to be in the sun for about two hours, use a sunscreen with SPF 30. Any longer, then use a sunscreen with SPF 40 and above. Apply sunscreen every two hours.

Snow screen: If you’re going to cold, snow-covered areas, a sunscreen is a must. Scientists says about 80 percent of the radiation is reflected off snow while sand reflects only about 25 percent.

Before and after: Apply sunscreen 30 minutes before you step out, for it to take effect. Reapply every two to four hours.

Skin specific: Choose a sunscreen that’s suited to your skin type. Use gel-based sunscreens for oily skin and lotion-based sunscreens for dry skins.
