…foundations, BB and CC creams. I see that they’re rated as highly as the straight sunscreens/sun creams. Theoretically, if we used the required 2mg/cm2 (1/2 tsp) of these products for the face, will they give the same level of protection as the straight sunscreens/creams? I’m asking because I’m wondering if I could be relying on a watery serum foundation for the entirety of my sun protection.
Yup! Anything that has an SPF is tested the same way.
While the US FDA, Colipa/ISO methods have a couple differences, it is always at the density of 2mg/cm2.
As long as it has an SPF rating, and you’re applying it at that density, you can be assured you’re getting that SPF – whether it’s called a serum, moisturizer, sunscreen, face pack, you name it!
Note of Interest: Only people with Skin Types I, II, or III are eligible to participate in the US FDA’s sunscreen testing protocol.
(I) Always burns easily; never tans (sensitive).
(II) Always burns easily; tans minimally (sensitive).
(III) Burns moderately; tans gradually (light brown) (normal).
Thanks for the question 🙂
