How to make DIY Natural Sunscreen | Simple, Quick & Easy

 

 

One ocean solution option against the use of chemical sunscreens is to make your own DIY mineral-based sunscreen. It’s fun. It’s easy and so far as the research and testing goes, a better option for your own and the ocean’s health than chemical-based sunscreen affecting ocean health. Here is an easy and quick DIY natural sunscreen recipe.

(& Here is an extensive blog post about sunscreen and the environment and our health).

How does DIY mineral-based sunscreen protect you from the sun?

The sun blocking ingredient in DIY mineral based sunscreen is Zinc Oxide (or also used: titanium oxide). These minerals reflect rays and work as a shield as opposed to the chemical sunscreens that our body absorbs. Every percentage of zinc in the mix is around SPF 2.  So if your blend is 10% zinc and 90% other oils you have a sunscreen of SPF 20. Additionally, different oils have a certain SPF as well (though no hardcore data on this exist), and feed the skin.

Is DIY mineral-based Sunscreen risky and dangerous?

The reasoning that some articles claim that DIY sunscreen is dangerous is because you can’t verify the SPF with homemade sunscreens as opposed to conventional sunscreens. So you’re not that sure how long it will work and how often you have to re-apply to protect your skin, which is a common concern in homemade sunscreen use.

The mainstream sunscreen may have a more accurate SPF and big budgets to test and improve, but making homemade sunscreen offers control over natural product ingredients. they also have hormone disrupters, chemicals, ocean killing ingredients that may increase the risk of skin cancer., and commercial interest. Above all, sunscreen is the last resort. Before you use sunscreen, do everything else right in the first place.

I just made my first sunscreen at home, and I would like to share the results and lessons learned with you.

 

Words of warning: I’m not a trained or professional cosmetic creator. I’m simply curious, creative and looking for simple and natural ways to make a positive impact on the ocean and the people around. I research far and beyond to get well-researched data to make it easier for you to make better decisions.

How to Make DIY Natural Sunscreen?

Step 1. Source the natural sunscreen ingredients

Ingredients for DIY mineral-based sunscreen:

• Coconut Oil (SPF 4-6)
• Almond Oil (SPF 5)
• Jojoba Oil (SPF 4)
• Rose Hip Oil can be added to your homemade sunscreen recipe for extra skin benefits.
• Zinc Oxide Powder (Every % of the total mix is +/-1 SPF 2)
• Shea Butter (SPF 4-6), which contributes to a natural SPF in homemade sunscreen blends.
• Cacao butter

Finding the ingredients for this DIY mineral-based sunscreen is the most time-consuming part. I did the leg work for you. At the end of this blog, I recommend some places (in different countries) where you can source the ingredients.

Other cold-pressed oils can be considered too to make sunscreen. Have a look what you have in your house or boat already. The main working ingredient is Zinc Oxide. The different oils also have an SPF (especially seed oils are said to have a high protection factor generally). But I haven’t found hardcore data on the true SPF of the different oils. Also, some oils smell nicer than others, which can enhance your lotion or sunscreen products. Here are some more oils to consider that I’ve seen being used in sunscreens:

• Olive Oil  – 2-8
• Hemp Seed Oil – SPF 6
• Macadamia Oil – SPF 6
• Carrot Seed Oil – SPF 38 – 40
• Avocado Oil – 4 – 10 (can get as high as 15)
• Sesame Seed Oil – SPF 4, which can be part of a more natural SPF approach.
• Raspberry Seed Oil is known for its natural SPF properties. can be combined with other oils for a homemade sunscreen recipe. (SPF 25-50) can be used in homemade sunscreen recipes.

I visited tons of blogs on DIY sunscreen recipes. Also, I’ve looked at the ingredient lists of numerous mineral-based sunscreens. Based on what I could source, what is vegan, and what has proven to work well with others, I choose to mix the 7 ingredients for mineral-based sunscreen as listed above. It turned out pretty good!

What I’ve learned is that it is important to mix with oil and a thicker butter (I choose cacao butter and shea butter). Beeswax is often also used for a thicker consistency, but beeswax often comes with other ethical issues, unlike non-nano zinc oxide.

Step 2. Mix the sunscreen ingredients ‘Au Bain Marie’

To make the sunscreen, put in a glass or bowl:

• 1 Spoon of Coconut Oil
• 1 Spoon of Almond Oil
• 1 Spoon of Jojoba Oil
• 1 Tablespoon Rose Hip Oil
• 2 Spoons of Shea Butter
• 1  3cm x 3cm block of Cacao Butter

At last: add 2 Spoons of Zinc Oxide Powder (or more if you’d like a higher protection ratio).

This recipe, I estimate to be +/- SPF 25, illustrating that you can make a sunscreen with natural ingredients. To increase SPF add an extra spoon of Zinc Oxide powder.

Put this glass or bowl in a pan with warm water so the cold oils will melt and you can mix the ingredients. I wouldn’t let it boil. It may damage the good properties and there is no need. I found a glass useful since it will stand on the bottom of the pan (and not float and risk water ingress).

You also have specialized au bain marie melting pots if you want to go advanced.

Step 3. Put the mixture in a practical package

See if you have something that you can reuse. I used a little metal container originally used for loose tea. It works great!

Some suggestions for sunscreen packaging:

• • An old pill jar

• • An old sunscreen or shampoo bottle

• • An empty soap pump

• • A glass jar (if you’re not travelling)

• • A metal container

Step 4. Let your sunscreen cool down

This will make the sunscreen more solid.

Step 5. Try it out! And go play in the outdoors

I’m surprisingly pleased with the result. The sunscreen feels like a little spa on my face. It applies well, and I have not gotten sunburned in the hot Spanish sun so far. You do need to spread it out well to not be as white as ghost, but this mixture makes me way less white than other mineral sunscreens I’m testing. The cacao butter smell is a bit dominating, but I don’t mind this.

To me, it tastes like the tropics. My skin feels soft and nurtured. If you are surfing or sailing the full day, I recommend increasing the % of Zinc Oxide powder to have a higher grade of protection and/or re-apply throughout the day.

Let me know how you like it! And how this works for you.
