Does SPF higher than 30 work?

High-SPF products don’t give you a whole lot more protection. But the truth is that higher-SPF products are only marginally better at shielding you from UVB, according to both the EWG and the Skin Cancer Foundation. SPF 30 blocks nearly 97% of UVB radiation, SPF 50 blocks about 98%, and SPF 100 blocks about 99%.

Is SPF 60 better than 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. Sunscreens with SPF 60 allow 1.7% of UV radiation to hit our skin.

Which is better SPF 20 or SPF 30?

So, doubling the SPF does not double the amount of protection one gets from sunscreen. If you apply sunscreen appropriately, the benefit from higher SPF amounts is marginal. However, most people do not apply a thick enough layer, so their SPF 30 may be more like an SPF 20.

Is SPF 30 or SPF 50 better?

A sunscreen with SPF 30 will protect you from around 96.7% of UVB rays, whereas an SPF of 50 means protection from about 98% of UVB rays. Anything beyond SPF 50 makes very little difference in terms of risk of sun damage, and no sunscreens offer 100% protection from UVB rays.

Is SPF over 30 a waste?

You can buy a product that is labeled as higher than SPF 30, but it’s almost always a waste, and potentially harmful. SPF 30 filters out approximately 97 percent. SPF 50 filters out approximately 98 percent. SPF 100 might get you to 99.

Why is SPF 100 bad for you?

Products with SPF values greater than 50+ also tend to give users a false sense of security. High SPF sunscreens not only overpromise protection but, according to the Food and Drug Administration, may also overexpose consumers to UVA rays and raise their risk of cancer.

Does a higher SPF matter?

An SPF 30 allows about 3 percent of UVB rays to hit your skin. Under ideal conditions (like in a laboratory), a sunscreen with higher SPF protection and broad-spectrum coverage offers more protection against sunburn, UVA damage and DNA damage than comparable products with lower SPF values.

How many SPF is enough?

Dermatologists recommend using a sunscreen with an SPF of at least 30, which blocks 97 percent of the sun’s UVB rays. Higher-number SPFs block slightly more of the sun’s UVB rays, but no sunscreen can block 100 percent of the sun’s UVB rays.

Does higher SPF damage skin?

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.

Is SPF 30 enough for daily use?

For day-to-day use, pick a sunscreen with sun protection factor (SPF) of at least 30. If you spend time outdoors, choose a product with SPF 60 or greater. In reality, most people do not use as much sunscreen as they should, and this higher SPF helps compensate.

Why is SPF 50 bad?

Is SPF 30 enough for everyday?

A dermatologist will always encourage you to wear it regardless, but if you regularly use retinol or chemical exfoliators, such as acids, your skin is likely to be more sensitive to UV light and therefore more prone to skin damage. If this is the case, be sure to wear sunscreen – at least factor 30 – every day.
