DermTV – Is Sunscreen SPF Additive Amongst Products [ Epi #72]

DermTV - Is Sunscreen SPF Additive Amongst Products [ Epi #72]

A common question asked about sunscreen is whether or not SPF amongst products is additive. For example, does your foundation with a SPF of 15 increase your total SPF to 45 if you’re also wearing a sunscreen with an SPF of 30? Dr. Schultz will explain.

  1. I have a cosmetic sunscreen. A sunscreen I can apply over cosmetics without smearing or removing them. If I have no SPF in my foundation and then apply my cosmetic sunscreen, will I get the effect?

  2. Hello, doctor!
    Could you tell me please, if I apply some tonic after wash my face and then SPFcream , will it be working? or I should apply SPFcream at once after washing my face?
    Thank you. =)))

  3. As long as they are both the same type of sunscreen (both either carbon-based or both chem-free-based) you will only get the SPF of the higher rated product. Keep in mind SPF greater than 30 confers very little additional protection over a sunscreen with an SPF of 30. I tell my patients to not get sucked into the numbers game with SPFs.

  4. hey doc, would it make a difference if u mixed the two together before applying it onto your skin? would it be somewhat additive then?
