Ultraviolet protection factor (UPF) is a rating system used to measure the effectiveness of sun-protective fabrics in blocking out UV radiation. The UPF rating system ranges from 15 to 50+ and indicates the percentage of UV radiation that is blocked by the fabric. For example, a fabric with a UPF rating of 30 will block out 97% of UV radiation, while a fabric with a UPF rating of 50+ will block out 98% or more of UV radiation. UPF 30 garment will allow only 1/30th (roughly 3%) of the sun’s UV radiation to reach your skin.
UPF-rated clothing can provide an added layer of protection against the sun’s harmful UV radiation, reducing the risk of skin damage and skin cancer. UPF clothing is also a convenient option for clients who may not want to apply sunscreen to their entire body, such as those with sensitive skin.
UPF is measured in a laboratory setting, but it is important to remember that UPF ratings can decrease over time with wear and tear. It is also important to note that UPF ratings only measure protection from UVB rays, which are the main cause of sunburn. UVA rays are also harmful to the skin and can cause premature aging, wrinkles, and skin cancer. It is important to choose clothing that provides broad-spectrum protection (protection from both UVB and UVA rays).
When recommending UPF clothing to clients, beauty professionals and estheticians should ensure that the clothing is appropriate for the intended activity and environment. For example, UPF-rated swimwear may be necessary for clients who spend time in the water, while UPF-rated hats and clothing with long sleeves and pants may be more suitable for those who spend time on land. UPF clothing should also fit properly and be comfortable to wear, as clients may be more likely to wear it if it feels good on their skin.
It is also important to note that UPF clothing is not a replacement for sunscreen. Clients should still apply sunscreen to all exposed areas of skin, including the face and neck, to provide maximum protection against UV radiation. Beauty professionals and estheticians can recommend a broad-spectrum sunscreen with an SPF rating of 30 or higher and remind clients to reapply sunscreen every two hours or after swimming, sweating, or towel-drying.
Here are some tips for choosing clothing with UPF protection:
- Look for clothing that is made from tightly woven fabrics, such as denim, canvas, and wool.
- Choose clothing that is a dark color, as darker colors absorb more UV radiation.
- Choose clothing that has a tight fit, as loose-fitting clothing will allow more UV radiation to reach your skin.
- Apply sunscreen to all exposed skin, even if you are wearing clothing with UPF protection.
UPF is a rating system used to measure the effectiveness of clothing and fabric in protecting against UV rays, while SPF is a rating system used to measure the effectiveness of sunscreen in protecting against UV rays from the sun. For more information, click on the following link:
