What is the best SPF for daily use?
The right amount of SPF: SPF 30 shields skin from 97% of the sun's UVB rays, and it's what the American Academy of Dermatology advises as a minimum for daily wear.
"It's best to use an SPF 30 on a daily basis even if you are not going to be outside," says board-certified dermatologist Azadeh Shirazi, who says to make indoor application a habit.
"Individuals with fair skin and hair, light-coloured eyes, freckles and moles are at highest risk of skin damage and should always use a minimum factor of 30 or 50," explains London-based consultant dermatologist Dr Justine Kluk, something Dr Mahto elaborates on.
Experts say sunscreens with an SPF higher than 50 aren't worth buying. They only offer marginally better protection. They might also encourage you to stay out in the sun longer. Instead, choose an SPF between 15 and 50, apply liberally, and reapply often.
The American Academy of Dermatology recommends using a sunscreen with an SPF of at least 30, which blocks 97% of the sun's UVB rays. The highest SPF is 100 and blocks out 99% of UVB rays.
The difference between a SPF 40 is you block out 97.5% of UVB radiation and SPF 50 blocks 98%. This is a very small difference for the cost of purchasing a SPF 50. More important than using a super high SPF is using enough sunscreen.
When used correctly, sunscreen with SPF values between 30 and 50 offers adequate sunburn protection, even for people most sensitive to sunburn. High SPF products may pose greater health risks. High SPF products require higher concentrations of sun-filtering chemicals than low SPF sunscreens do.
What kind of sunscreen is best for the face? Ensuring that you're applying enough SPF is also crucial. “I recommend looking for a broad-spectrum SPF of 30 or higher, and re-applying it every two hours,” says Dr. Gohara.
Berson: An SPF 50 offers a high level of protection and is best for those with a history of skin cancer or those that are fair skinned or at higher risk for skin cancer. An SPF 15 covers 93% of UVB rays and an SPF 30 covers 97% of UVB rays.
In terms of how much protection an SPF 30 provides versus an SPF 50, SPF 30 blocks 97% of UVB rays and SPF 50 blocks 98% of UVB rays. Interestingly, the difference between 30 and 50 is pretty marginal at about 1%.
Is SPF 50 safe for face?
Is SPF 30 or 50 better for your face? According to both the EWG and the Skin Cancer Foundation, SPF 30 blocks nearly 97% of UVB radiation while SPF 50 blocks about 98% and SPF 100 blocks about 99%. 31%. So technically speaking, SPF 50 is the best facial SPF... but only marginally.
A sunscreen's sun protection factor (SPF) is only fully effective for two hours after you put it on. Experts recommend carrying a bottle of SPF 30 to SPF 50 sunscreen around with you, even on cloudy or rainy summer days, so you can throw some on if the sun comes out.
Generally, SPF 100 is the highest protection you can buy, but it's not necessarily the best protection against a sunburn. According to Penn State Prevention Research Center, proper and repeated application of sunscreen is more important than the SPF number.
After that, the difference in protection is small. SPF 50 blocks 98%, and SPF 100 stops 99% of UVB rays from reaching your skin.
The protection factor of SPF 30 is not double that of SPF 15, nor is SPF 60 twice as effective as SPF 30…… The rationale behind this myth is that if SPF 30 can filter out 96.7% of UV rays, while SPF 60 can filter out 98.3%, the resulting difference is only 1.6% - thus SPF 60 must only be marginally better than SPF 30.
According to Yale Medicine, one way to prevent wrinkles and other symptoms of photoaging—when your skin prematurely ages due to increased sun exposure—is to wear a broad-spectrum sunscreen that has a sun protection factor (SPF) of 30 or higher.
Longer protection: SPF 50 sunscreens can protect your skin for longer, which means you have to reapply less often. Many SPF 50 sunscreens recommend reapplying every 150 minutes rather than the recommended 120 minutes for SPF 30.
Ideally, any sunscreen with sun protection factor (SPF) between 15 to 25+ will help protect you from daily sun exposure. However, if you are staying outdoors for a longer period of time, then opt for a higher SPF. Also, choose a sunscreen which is non-sticky or non-greasy, as this will not make your skin too sweaty.

Is SPF 50 harmful for skin?
The Sun Protection Factor or SPF 50 sunscreen for the face allows for better protection only if applied with other skincare products. People regularly swimming should not limit SPF to 50 or 30 for the face but should go for more to keep the skin away from chemicals.
In theory, sunscreen with super-high SPF should give you the best protection against damaging UV radiation. But in practice, it may not work that way. In fact, some experts say using super-high-SPF sunscreens could lead to more UV exposure — upping your risk for both burns and skin cancer.
A product with an SPF level of 15 will block around 93% of the sun's UVB rays. You will often find SPF 15 in makeup and skin care products. However, in sunscreens, the industry standard, and the SPF recommended by Dermatologists is generally SPF 30 and above.
With the rule of nines, the body's surface area is divided into 11 areas, each representing roughly 9% of the total (box). Sunscreen can be applied to each of these areas at a dose of 2 mg/cm2 if two strips of sunscreen are squeezed out on to both the index and middle fingers from the palmar crease to the fingertips.
“As long as it's SPF 30 or higher and has broad spectrum coverage, it is safe,” says Dr. Turegano. By opting for a moisturizer with SPF, you get the best of both worlds—skin-loving ingredients and protection from UV rays.
How do you choose between them? SPF 30 is the most common level for most people and skin types. No sunscreen can block all UV rays, but what we do know is: SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97% of UVB rays and SPF 50 blocks 98% of UVB rays. So, the difference between 30 and 50 is about 1 percent.
For the best protection when you'll be outside all day at the pool, park, beach, amusement park or elsewhere, SPF 30 or higher is ideal. Here's what the major health authorities say: The American Academy of Dermatology recommends using sunscreen with SPF 30 or higher.

If you're out and about, there is no need to wash your face before reapplying sunscreen. You can just reapply right on top! However, if the layers of sunscreen feel too heavy on your face or your face begins to accumulate dirt, you can also use a gentle makeup remover wipe to start fresh.

Wash It Off
Even though your sunscreen is no longer effective, you should be sure to wash your face before going to sleep. While the actives in your sunscreen may be not-so-active anymore, there is probably sunscreen still left on your face. So at the end of the night, you do still need to wash your face.
There are no direct adverse effects of applying a higher SPF, but it can lead to a sun protection routine that is incomplete and needing more. While a product with SPF 50 might give you better protection against UVB rays due to its photochemistry, it might have less UVA protection. Both radiations are equally harmful.
Everyone, regardless of age, gender or race, should use sun protection factor (SPF) of 30 or higher. But what's in your sunscreen may be just as important as the SPF number. While SPF 85 sounds like it offers more protection, higher SPF numbers can be misleading.

When used correctly, sunscreen with SPF values between 30 and 50 offers adequate sunburn protection, even for people most sensitive to sunburn. High SPF products may pose greater health risks. High SPF products require higher concentrations of sun-filtering chemicals than low SPF sunscreens do.
