The other day, it occurred to The Beauty Bug that both her morning moisturizer and her primer contain SPF. The morning moisturizer, RevaleSkin Coffeeberry Day Cream, contains SPF 15, and her primer, MAC Prep + Prime Face Protect contains SPF 50. So did that mean She was protected with SPF 65 everyday this summer, or were they counteracting each other and therefore becoming less effective? The Beauty Bug had to go straight to the source – She contacted a Sephora Beauty Advisor and here’s what they had to say:
Dear Beauty Bug:
When using multiple sunscreens, you are not raising your protection level – the SPF will be the highest of the 2 – 50 in your case. With regards to mixing sunscreen, I have nor heard of any definitive studies indicating that the stability of the sunscreen can be compromised, however it’s certainly possible. I prefer to use a single daytime sunscreen of SPF 30 for optimal protection.
Hmmm…not what The Beauty Bug wanted to hear…
