Another Beauty Pro Weighs In On the Sunscreen Question

Another pro has weighed in on the "do I apply sunscreen before or after my other skin care question." This time, the cosmetic chemists from The Beauty Brains tell us their thoughts on Dr. Neal Schultz's claim that has me concerned that I am not protecting my delicate punim in the proper way.

The Beauty Brains, specifically the Left One, don't think the answer is quite as cut and dry. In fact, they aren't sure if there is a right answer. I'll let them explain:

You raise some interesting questions and the truth is this question is one for which science hasn't determined an answer. Good arguments could be made for both methods of application. Until there is a definitive study, there is no known "right" answer. But take heart, there is not really a "wrong" answer either.

Here is what the Brains conclude (with all due respect to the doctor) about these issues.

For physical blocking sunscreens (minerals) like Titanium Dioxide or Zinc Oxide, it doesn't matter. They'll work just the same whether it's put on first or last. In this case, we recommend putting it on after your moisturizer just so the sunscreen doesn't inhibit the penetrating ability of the moisturizer (or other treatment).

Chemical sunscreens (e.g. Oxycinnamate) are a bit different because the raw materials in the formulas can have an impact on the final SPF rating. That means if you apply it after your moisturizer, you may reduce the SPF efficacy.

So, Zinc & Titanium on last, all other sunscreens on first.

Of course, you could actually solve the entire problem by using a moisturizer that contains sunscreen.

As for the question about the eye creams or serums. Again, the science hasn't been done but there is a good rationale for using them at night rather than in the morning. Many of the active ingredients are UV sensitive so they will most likely be less effective if exposed to the sun. Wearing products at night prevents this problem.

Thanks for your help, Brains!
