Homemade Sunscreen; Concerns about chemicals have led do-it-yourselfers (DIY) to make everything from laundry detergent and soap to deodorant and toothpaste at home using natural ingredients. As summer begins, the DIY crowd is also whipping up batches of homemade sunscreen; so using recipes that mix zinc oxide with coconut oil, shea butter, Vitamin E and other ingredients.
Dr. Colette Pameijer, a surgical oncologist and skin cancer specialist at Penn State Health, said a survey of the often use recipes, couple with scientific information about the trend, tells her that making your own sunscreen is an incredibly bad idea. They am a vegetarian and health nut, so I totally get it that people want to limit the chemicals in their life, she said. “But the chemicals in sunscreen are good chemicals and they serve a very important purpose.
The Homemade Sunscreen
Most home sunscreen recipes use essential oils and zinc oxideor titanium dioxide. While essential oils are untested, zinc and titanium are legitimate sun blockers, although different from sunscreens. Zinc and titanium are mechanical blocking agents, which means; so they work as long as they are on the skin and physically blocking the rays, Pameijer said. As soon as they are wash off or sweat off, you are left unprotect from the sun.
Pameijer said the dangers of ultraviolet rays are so much more obvious and immediate; so than any potential risks from the ingredients in sunscreen. Sunblock functions through a chemical reaction on the skin; so that creates a mechanical barrier. While some of those chemicals are absorb by the skin; so she is not aware of any data to support long-term damage.
Just because a substance is absorb doesn’t necessarily mean it’s bad, she said. They think the benefit of sunscreen is prove and the risks are speculative. To be effective, the active ingredients in sunscreen; which must be properly disperse and stabilize throughout the mixture; also that’s hard to achieve without professional laboratory equipment. The formulation then test for effectiveness and SPF value.
Unless you are testing it yourself and letting yourself burn each time you make a new batch, you really can’t determine the SPF, she said. It doesn’t make any sense to do that. Pameijer recognizes that many people have sensitive skin and react to some brands of sunblock on the market because of the chemicals they contain.
Common sunscreen additive
They am one of those people, she said. But there are a ton of different products available. You may have to shop around a bit before you find something you like. Some people react adversely to oxybenzone, a chemical in some newer formulations of sunblock that also protect against deeper-penetrating UVA rays that cause skin damage, wrinkling and cancer. UVB rays are the ones responsible for producing sunburn and are what most sunscreens protect against.
Another common sunscreen additive that can cause allergic reactions is para-aminobenzoic acid, or Paba. Another option is to use sunscreen only on your face and hands and wear clothing that protects against ultraviolet rays. They think they work better than any sunblock on the market,” she said. They drastically reduce your amount of exposure.
Pameijer said it’s especially important to protect children because heavy sun exposure early in life is a risk factor for skin cancer. While those with darker natural pigmentation to their skin may be less likely to burn or develop melanoma, she still recommends they use sunscreen religiously. They can develop other cancers and premature aging, she said. Your skin will still get damaged.
