What Spf Number Do Doctors Recommend You Use When Exposing Yourself To The Sun?

I was told you need at least 15. The more fair skinned you are the higher the S P F (sun protection factor)
And the only way to know is trial and error

Doctors recommend an SPF of at least 15.  I try to use SPF30 because I have light skin.  They also recommend that you have protection from both types of rays.

An spf 15 is recomended for those who visit the sun for short periods of time. The longer the time/and often determine what you should use. If you work in the sun everyday you should use the highest value. Water resistant spf available. Wide brim hats help also.

They recommend a 30 spf or stronger. Hope this helps.

Spf 45 for really light skin. At least over 30.

They recommend at least 15. They also recommend blocking  UVA and UVB rays, not just one type. I try to use SPF30 because I have very light skin.

My Doctor said 50

I've heard 30 or more.

They recommend 18 or higher and you should reapply it according to the guidelines on the bottle.

I use 20 when I think I need to . Jim123

My doctor said 50

45 or higher

30 or more

I never let the sun see it. Well maybe sometimes...

I have not yet consulted with the Doctor regarding this.
