How does zinc help in sunscreen lotions

How much zinc oxide for which sun protection factor?

Sun protection factorzinc oxide

For SPF 6 to 1110 %
For SPF 12 to 1915 %
For SPF 20 and higher20 %

More than 20 percent zinc oxide should not be used, otherwise the cream will become more of a paste that is difficult to apply. If you need a higher SPF, it makes more sense to use a sunscreen from the health food trade, e .g. from Biosolis o.

Homemade sunscreen - the ingredients

  1. Coconut oil With a natural SPF of 7, which at the same time protects the skin from bacteria, fungi and, to a certain extent, also from vermin such as ticks
  2. Shea butter with a natural SPF of 4
  3. Jojoba oil cares and nourishes the skin
  4. Essential oils give your sunscreen a good scent. The addition of essential oils can also slightly support sun protection. Eucalyptus oil provides an SPF of 2.5 and lavender oil an SPF of 5.5. But the added quantities of essential oils are of course very small, which is why the effect is not outstanding. However, when you consider that citrus essential oils - which should by no means be used in sunscreen lotions - increase the skin's sensitivity to light, it becomes clear that it's extremely important to use only the right essential oils in sunscreen lotions.
  5. Vitamin E oil nourishes the skin, gives it moisture and protects it from free radicals. At the same time, vitamin E acts as a natural preservative so that your homemade sunscreen does not spoil too quickly.
  6. Zinc oxide (non nano) is a UV filter that absorbs UVA and UVB radiation and keeps it away from the skin. "Non nano" means that the zinc oxide particles are larger than 100 nm and cannot get into the body through the skin pores, but remain on the outside of the skin and do their job there - sun protection.

Homemade natural sunscreen - the recipe

For your self-made sun cream you will need the following quantities as well as mouth and nose protection (dust mask made of paper) from the hardware store:


  1. 30 g coconut oil
  2. 24 g shea butter
  3. 3 g jojoba oil
  4. 3 g of vitamin E oil
  5. 30 drops of essential oils (100%), e.g. B. 15 drops of lavender oil and 15 drops of eucalyptus oil or just 10 drops of eucalyptus oil plus 5 drops of mint oil
  6. Zinc oxide powder depending on the desired SPF


Put coconut oil, shea butter and jojoba oil in the warm water bath. Gently heat the water until coconut oil and shea butter have melted and remove the oils from the water bath. Let the oils cool down a bit.

Put on the dust mask so as not to inhale the zinc oxide dust, measure the zinc oxide and add it to the oil mix together with the vitamin E oil and essential oils. Stir everything in well, pour your sunscreen lotion into a dark glass jar or a cream jar and store it in the refrigerator.

The sunscreen will last about 6 months if stored in a cool and dark place. If you take the sunscreen with you to the swimming pool or the beach, make sure it is stored in the dark and put it back in the refrigerator overnight.

Use the sunscreen just like any other sunscreen. Apply it several times a day, even more if you go into the water in between or if you have sweated a lot.

I wish you a happy summer and a great vacation
