Archived DIY Sun-Protection Mixtures: Safety Notes
This archived post preserves the context of two homemade mixtures containing oils, wax, zinc oxide, and essential oils. It is not a sunscreen recipe: a homemade mixture cannot be assigned an SPF value, broad-spectrum protection, even coverage, or water resistance.
Why an archive recipe is not sunscreen
The original post suggested mixing oils and wax with zinc oxide powder and essential oils. An ingredient amount alone does not establish an SPF claim, UVA/UVB coverage, or water resistance: those claims require testing of the finished product. Do not use a homemade mixture in place of a labelled, tested sunscreen.
Do not mix loose zinc oxide powder at home for skin application: it can be inhaled while being handled, and it cannot be distributed evenly in a mixture without testing. Essential oils, especially citrus ingredients, can irritate skin, cause allergy, or increase sun sensitivity. Do not add them to a product intended for sun exposure.
More reliable sun protection
For time in the sun, choose a ready-made, labelled broad-spectrum sunscreen and use it as directed. Do not rely on sunscreen alone: add shade, protective clothing, a hat, and sunglasses. Children need the same layered protection; choose products and sun exposure appropriate to the child’s age and the product instructions.
This post remains as an archive note about homemade mixtures, not instructions for making an SPF product. Seek medical care for a severe burn, blistering, or feeling unwell after sun exposure.
I had not heard of that idea before, but a balcony still exposes skin to sunlight. Carrot juice in a homemade cream cannot make tanning safe or prevent burns; use a labelled sunscreen as directed and seek shade or protective clothing as well.
