SPF stands for “Sun Protection Factor”. It measures the amount of time it takes for sun-exposed skin to redden, while UPF measures the amount of UV radiation that penetrates a fabric and reaches the skin. Remember that SPF only accounts for UVB rays unless specifically stated as a broad-spectrum sunscreen.

Is UPF 50 the same as SPF 50?
UPF stands for ultraviolet protection factor and is the sun protective rating for fabrics, most commonly referred to with sun protective clothing. The rating system works the same way as for SPF. The maximum UPF rating that can be awarded is UPF 50+, which blocks at least 98% of UV radiation.
Is UPF and SPF the same thing?
How does UPF differ from SPF? UPF measures the amount of UV radiation that can penetrate fabric and reach your skin. Sun Protection Factor, or SPF, is based on the time it takes for UV-exposed skin to redden; if you burn after 20 minutes, if used correctly, an SPF 15 sunscreen may protect your skin 15 times longer.
What is a good UPF rating?
The higher the UPF rating, the greater the protection it offers. For example, UPF 50 allows only 1/50th of the sun’s UV radiation to reach the skin. “There are three categories for labeling UPF garments,” Kylene says. Good is 15-24%, Very Good is 25-39%, and Excellent is 40-50+%.
Which is better UV or SPF?
In sunscreen, SPF helps to block your skin from the sun’s radiation. The sun emits two types of radiation: UVA and UVB rays. UVA rays contribute to the signs of aging in the skin, like wrinkles and sagging. UVB rays are more carcinogenic and often responsible for sunburns.
Do you wear sunscreen under UPF clothing?
Do I need a sunscreen with my UPF clothes? Since UPF clothing protects from 98% of the sun’s rays, there is no reason to put sunscreen underneath the UV clothing. If you prefer to apply sunscreen underneath, we recommend to apply it 15 minutes before you wear your UV protective clothing to prevent staining.
Does UPF wash out of clothing?
Depending on the durability of your clothing, the fabric composition may be compromised after only a couple washes. In other words, as the threads thin out, the shirt allows more UV light to pass through. So while the UPF does not necessarily “wash out,” the UV protection rating will eventually drop over time.
How long does UPF 50 clothing last?
UPF clothing lasts approximately 30 to 40 washes; with regular use, the clothing should last about one year.
Which color is best for sun protection?
Dark or bright colors
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays. The more vivid the color, the greater the protection—a bright yellow shirt is more protective than a pale one.
Can UV rays go through clothes?
While UV rays can go through most clothing, especially if the colors aren’t dark, you can purchase special outdoor clothing that blocks UV rays.
Can I wear a hat instead of sunscreen?
Hats can be a useful addition for sun protection of your head, ears, face and neck, but they will rarely provide sufficient protection on their own to anyone outside during times where sun protection is advised (when the UV level is 3 or higher).
What SPF is normal clothing?
5
“Most cotton shirts give you an equivalent of about a UPF of 5 when you’re wearing it,” Dr. Vij explains. “Most fabrics that we wear are a loose weave that lets visible light peek through and get to our skin.

Which SPF is best for sun protection?

Dermatologists recommend using an SPF of at least 30, which Adarsh Vijay Mudgil, MD, a dermatologist practicing in New York, calls “the magic number”. SPF 15 blocks about 93 percent of UVB rays, while SPF 30 blocks about 97 percent of UVB rays. The ADA recommends an SPF of 30 or higher.
Does higher SPF damage skin?
A SPF indicates how much longer it will take to burn with sun protection e.g. the skin should take 30 times longer for it to burn with an SPF30, than without. The higher the SPF, the higher the concentration of chemical sunscreen ingredients, in fact, high levels of chemicals induce higher risk of free radical damage.
