Hi Michelle,

Thank you so much this was a great breakdown! I wonder if you have any information on how to assess/verify the quality of individual sunscreen products (or brands as a whole)? I was just reading the Consumer Reports assessments on sunscreen products, and it looks like a lot (all?) of them don’t live up to the SFP they are labeled as, and I’m not sure what to make of that. Are there standards for ingredients/percent concentrations to look for? Or other sources where the efficacy of products are published?

Radio waves should be fine, since they’re very low energy. I’m not 100% sure about x-rays, but I don’t think they should be a huge issue – the amount of x-rays used these days for carry-on baggage is too low to even register on photographic film, the amount used for checked baggage is higher but still very low, and I would expect some of these processes would be used for commercial imports as well.

You are truly amazing! Thank you for providing us with this information. I have a question that I’ve been trying to figure out for a while now, I can’t find anything about it online and the only person I could think of who might know the answer was you. Can for example x-rays and metal detectors used in airport checks affect sunscreens in any way? I usually take quite a few bottles with me when I travel. This thought brought up another question, can keeping the sunscreen
near a cellphone affect sunscreen? (I’m thinking of the radio waves). For example having them both in the same pocket or bag, or just close. I really apologize for the long questions but these thoughts really haven’t been able to leave my head

In reply to Mary. Thank you! I do sometimes think about how much money I could make if I didn't have a conscience

Lots of people want to make money sitting on their bum in front of a camera. To do this you need “content”. Content that is associated with sex or fear or death etc gets a lot of hits. This is how to make money on social media. There are only a handful of YT content providers I bother to look at and Lab Muffin is one of them.
