About a month ago a friend asked me via Twitter about homemade sunscreen. I promised him a more thorough reply than a tweet, and this is it.
When I first realized I could make my own lotion and I could buy titanium dioxide and zinc oxide, I immediately wanted to make my own sunscreen. I did a lot of research and found recipes that seemed simple enough; lotion + zinc oxide and/or titanium dioxide. Then I did some more reading.
Sunscreen is one of a few defences we have against the sun. And melanoma. That is why sunscreen is thoroughly tested in labs to make sure it will do the job and keep your face from peeling off. Homemade sunscreen is not tested except for on you. I don’t know about you, but I don’t have a lab in my basement, or anywhere else in my house.
I also know that I don’t want skin cancer, and while I’m ok with testing the effects of argan oil (USA / Canada) on my face, or body butters on my hands, I don’t want to leave cancer protection up to my DIY devices. And I don’t think you should, either. Would you make your own penicillin or ski helmet? I didn’t think so.
