2-Minute, 2-Ingredient DIY Sunblock

7.13.12 104If you’ve read my blog at all then you know that I have a kid who reacts to lots of things – including sunscreen. A fun-filled day trip to Coney Island resulted 2 weeks of no sleep due to the itchy rash that he got where ever we had put sunscreen on him. What does that mean? No more sunscreen for us! So, what’s a mom to do? Make her own of course.

I immediately went to the internet and researched all the homemade sunscreen and sunblock recipes. I came away knowing that I wanted to go with a zinc oxide based sunblock since that seemed to have the best safety profile and effectiveness ratings. However, I didn’t want to spend the money on a huge bag of zinc oxide powder from Amazon. (Note: It is much more affordable now than it was when I was looking 3 years ago and available in smaller bags.) So, necessity breeds creativity here. I was in the drug store and realized that Desitin is 40% zinc oxide. Immediately I knew I had instant sunscreen here.

Now, you may be thinking, “Wait a minute. There is no way I’m rubbing that white gooey stuff all over myself and my kids. What a mess!” And you would be right. Yet, never fear. All you need is 2 minutes to turn that Desitin into a smooth, lotiony sunblock.

Most zinc oxide sunblocks with an SPF of 30 are 20% zinc oxide. Which means that if you mix equal parts Desitin and your favorite lotion, it cuts the percentage of zinc oxide in the mixture by half and you have an instant SPF 30 sunblock! It’s that easy.

I’ve used this  Desitin sunblock with my homemade lotions for the past three years and it works great. I find that this sunblock is fairly waterproof, but if you want to improve that “waterproofness” of your mixture then add a little bit of liquid lanolin to it. Our oldest loves the water and has played for hours in the full sun without a sunburn. So, what are you waiting for? Everyone run to their medicine cabinet and pull out that tube of Desitin and start mixing!

If you want to make your own lotion first to mix the Desitin with, you can visit the Herb Shed and scroll down for directions and more sunscreen tips and recipes. If you use regular lotion and find that you can’t get the Desitin to blend well, then melt the two ingredients (lotion and Desitin) in heat proof bowl over a small saucepan (double boiler technique) until it is blended. I like to mix it with a popsicle stick so that I can just throw it out when I’m done and don’t have to worry about cleaning the mixture off of my spoons. The other nice thing about this recipe is that you can make small batches easily so that you don’t have to worry about unused sunscreen, or you can make a large batch if your family goes through a lot of sunscreen.

Here’s to a happy and sunburn free summer!

Note: Zinc oxide can stain dark clothing so take care when applying it. Also, individual results can vary so use with care and common sense. The author is not responsible for any adverse reaction or sunburns if you choose to use the recipe recommended here. Read my full Disclaimer here.
