Sunlight is the best source of vitamin D for the body. But, it has extremely harmful ultraviolet rays which can cause numerous skin issues. This is why experts regularly stress on the usage of sunscreen.
Pilates trainer Yasmin Karachiwala recently teamed up with dermatologist Dr Jaishree Sharad who answered a few FAQs on sunscreens.
What does sunlight comprise?
Sunlight comprises ultraviolet A, B, and C, visible light, infrared rays, and blue light. As per Dr Sharad, while ultraviolet B causes skin cancer, all other types of rays cause hyperpigmentation, early signs of ageing, uneven skin tone, allergy, rashes, sunburn, suntan, etc.
What kind of sunscreen should you pick?
Dr Sharad recommends picking sunscreen according to oneтАЩs skin type.
*Oily skin- Water-based/matte sunscreen
*Dry skin тАУ Ceam-based sunscreen
*Normal skin тАУ Any type of sunscreen
*Sensitive skin тАУ Mineral-based sunscreen
How much SPF should a sunscreen have?
SPF means sun protecting factor. While SPF 30 is good, Dr Sharad suggested that one тАЬshould use 50+ SPF for hyperpigmented skinтАЭ.
тАЬWe should look after the PA value in sunscreen as that protects us from ultraviolet A. PA value should be either triple plus (+++) or four plus (++++),тАЭ she mentioned.
Should you re-apply sunscreen?
тАЬIf we are outdoor, we should reapply every two hours even if our sunscreen contains SPF 30 or 50,тАЭ she said.
How about indoors?
тАЬWe need to use sunscreen indoors because our cellphones, television, laptop, computers, etc all emit blue light which can be very damaging for our skin,тАЭ she said.
