How high of an SPF do I need to protect my skin?

Let's start with some facts

SPF (or sun protection factor) is a measure of the amount of time you can spend in the sun before getting a sunburn. But SPF only measures protection against UVB (burning) rays. It does not measure the level of protection against UVA (aging) rays, which have been linked to wrinkles and skin cancers. For best protection, your sunscreen should always contain ingredients to protect you against both UVA and UVB rays. So look for a broad-spectrum sunscreen.

One of the common myths is that using a sunscreen with twice the SPF gives you twice the amount of sun protection. This is not true. A sunscreen with a higher SPF will only give you a slightly higher level of protection, but will protect you for a longer period of time than one with a lower SPF. However, this can be misleading because most people donít apply enough sunscreen to give them adequate level of protection to begin with. Sunscreen does rub off on clothes, furniture and whatever else you may rub against. When you perspire or go in the water, your sunscreen will come off (even the waterproof kind) and will need to be reapplied. So focus less on the SPF number and more on making sure to reapply your sunscreen every couple of hours or after swimming.

Lastly, remember that if you apply several products with an SPF, it doesnít mean you are getting more protection or that you donít need to reapply your sunscreen.

SPF15 Moisturizer + SPF15 Makeup ≠ SPF30 protection

What you need to do to get adequate sun protection:

       1. Choose a broad spectrum UVA and UVB sunscreen with an SPF 15 or higher.

       2. Look for a sunscreen with zinc oxide, titanium dioxide, or mexoryl.

       3. Apply an adequate amount of sunscreen: a tablespoon to cover the face and about
       a shot glass size to cover the body.

       4. Reapply sunscreen every 2 to 3 hours, and after swimming.
