Sun Protection Factor aka SPF
This acronym is thrown around so much, it’s very easy to miss out on what it actually means. Sun Protection Factor, refers to how much longer you can stay in the direct sunlight if you weren’t wearing sunscreen. For example, when wearing SPF 30, you can stay in the sun 30 times longer than if you were wearing no sunscreen at all. You are also, essentially being exposed to 1/30 of the rays you would be were you not wearing any.
Additionally, people often apply sunscreen just once. Most sunscreen last for about two hours if you’re not in the pool. While water-resistant formulae last around 40-80 minutes, reapplying in the midday sun is especially important.
For rosacea, acne and allergy-prone skin
Avoid all products which contain preservatives, fragrance and PABAs. Gel formulae are less likely to aggravate acne, as they usually contain small amounts of alcohol. This is less drying. Skip greasy sunscreens, and look for water-based products.
For dry skin
Look for creams, oil-based lotions or ointments. Moisturisers with inbuilt sunscreens are also a good option, which include lubricants like lanolin, oils and silicones.
For kids
Chemicals in sunscreens can irritate sensitive baby skin as PABAs and Oxybenzone have been known to cause adverse reactions. All natural and organic sunscreens are now available in the market, including brands like L’Occitane and Kama Ayurveda.
Is bigger better?
It is easy to mistake that SPF 30 is twice as better as SPF 15. But, the reality is that anything after 30 is about the same. Properly applied, SPF 50 shields you from 98 per cent of all damaging rays, while SPF 100 blocks you from 99 per cent. A lot of studies show that higher SPFs are merely a marketing gimmick, as no sunscreen can protect you entirely. However, SPF 30 is a gold standard.
Physical or chemical?
Physical sunscreens absorb light, and protect you from both UVA and UVB rays. While they last longer, they also rub off the minute you get into the water. Chemical sunscreens reflect light, are thinner and easier to apply, but can leave a chalky white telltale. They, also make your skin a little prone to irritation.
Label talk
Zinc oxide and titanium dioxide are essentially what block your skin from harmful rays, so watch out for these names on your label. Ensure they are broad spectrum — that protects from both UVA and UVB rays.
Stay with sprays
Spray sunscreens are becoming a popular option, for ease of use and convenience. However, it is important to run it in just like you would with a cream sunscreen. Additionally, never spray sunscreen directly to your face. Spray on your palms and massage it in.
All the way
While sunscreen is key, other precautions play a huge role, too. Your clothes can reduce risk of a sunburn by 28 per cent. Right clothes and staying in the shade is key. Also, wear sunglasses and download an app to tell you what the UV index is, before heading out.
