What does SPF 50 mean?

According to Consumer Reports, an SPF 50 rating enables someone who normally burns in the sun after 20 minutes of exposure without any sun protection to stay in the sun for 600 minutes with the SPF 50 without burning.

To understand how the sun protection you choose can prevent you from burning, use this formula:

Multiple the number of unprotected minutes (UM) you can stay in the sun without burning by the SPF (SPF) rating of the sunscreen = total time (TT) you may stay in sun without burning.

SPF formula: UM x SPF = TT

Important notes:

• SPF does not account for UVB protection.
• Choose a broad spectrum sunscreen to ensure you have protection from both UVA and UVB rays.

Additionally just because you are not burning, doesn’t mean you are not exposing your skin to possible sun damage, premature aging, and hyperpigmentation.

• Limit your time in the sun
• Always use sun protection, a minimum of 15 SPF
• Reapply your sunscreen as directed
• Protect your head, face, and neck with a hat
• Protect your eyes with sunglasses
• Wear protective clothing
