If you have been following my blog, then you probably know I am serious about getting the chemicals out of my house and off of my children! It seems that everything you buy in the store is a chemical soup. Enter sunscreen. Wow the list of chemicals is looooong! So, I bought the natural kind, made with good ingredients. Great stuff, hefty price tag! That’s when I decided to just give it a go and make my own. Guess what? It’s super easy, cost effective, and completely non-toxic — plus, my recipe is actually good for your skin! Bonus: it is also DIY waterproof sunscreen!

Note: I get a lot of questions about where to buy if you don’t want to make your own sunscreen. There is a great one you can buy that is rated a 1 by the EWG! You can find it HERE. I also love their sun stick that you can toss in your purse and diaper bag!

DIY Waterproof Sunscreen


  • 1/2 cup coconut oil — contains a natural SPF of 10 — where to find
  • 1/4 cup sweet almond oil — great for skin elasticity — where to find
  • 1/4 cup beeswax — where to find
  • 2 Tbsp Shea Butter — I love this brand!, they even send you a free recipe book for more DIY stuff!
  • 1 tsp Vitamin E — keeps your lotion from going rancid and is good for your skin — where to find
  • 2 Tbsp Zinc Oxide powder  — contains a natural SPF of 20 — where to find
  • Optional: I love to add lavender essential oil to mine because it gives it a wonderful scent and is very beneficial to the skin. I typically add about 30 drops, after it is all mixed up and has cooled a bit. I only use therapeutic grade essential oils, so I am sure that the quality is to my standards (especially for use on my kids!). Here is the kind we use.

  • Warm over medium heat until everything is melted, but don’t let it get too hot or the next step will be painful!
  • Pour into a glass jar, add in the zinc

  • Put a tight lid on the jar and shake really well (the reason for this step is so you avoid breathing in the zinc powder). Be careful, it can be hot. I wrap a towel around the jar when I shake it!

  • Pour into desired containers. I use cute jelly jars (like these), or for at the beach I use refillable silicon tubes (like these)
  • Allow to cool completely before using
  • Use when out in the sun for prolonged periods of time, reapply as necessary. This stuff lasts, even in the water! Gotta love DIY waterproof sunscreen!
  • It makes about 1 cup and lasts for quite a while — I have not had it go bad yet. I also store it in the fridge in the winter to keep the oils from going rancid
