So far my research relating to Dr. Neal Schultz's claim that sunscreen should be applied last has yielded slightly varying results. I was able to get in touch briefly with Jan Marini, a respected national skin care authority who has dedicated more than three decades to researching and developing new and innovative skin care technologies. Jan is also the creator of one of my all time favorite products, The AntiOxidant Daily Face Protectant, a sunscreen with an SPF of 30.
Jan said, "hands down, sunscreen goes last. If you were to put it on first, it would likely dilute the tenacity of the sunscreen."
Considering reducing the effectiveness of my sunscreen is the last thing I want to do, I am sticking with applying my sunscreen last.
Thank you to everyone who has spent time explaining the science behind this and weighing in with your theories. There is a lot more that goes into the science of being beautiful - I only wished I had paid more attention in chemistry.

I had seen this video before and was totally confused. It seems like the best thing to do is where a Titanium Dioxide based sunscreen (or Zinc) and apply it last. The last thing I want is sun damage when I spend a lot of money to get rid of sun damage! Thanks, G!
ReplyDeleteKelly - I'm very happy to read that you've been watching episodes of DermTV and appreciate your engaging with them and the topics. If there are ever any topics that you'd like covered, please drop me a line via the contact page on DermTV. Regarding the above, I just wanted to make note of the fact that I believe that sunscreens should be applied first and not last. In addition, I also wanted to share with you a link to an in-depth discussion of why I advise my patients to apply sunscreen first.
ReplyDeleteThanks for weighing in, Dr. Schultz! And thank you for the additional link - more to consider.
