1. Avobenzone Avobenzone is a primary agent in commercial sunscreens due to its effectiveness in absorbing a wide range of ultraviolet (UV) rays, specifically the type that is known to cause sunburn. It’s been considered a relatively safe chemical, but recent research suggests otherwise. Avobenzone degrades in the sun, resulting in the release of free radicals that may actually increase the risk for cancer.  
Free radicals are also known to accelerate skin aging and research has also tied it to a slew of allergies. 
2. Fragrance Sunscreen is often injected with a variety of artificial fragrances as a means of making the product more appealing and tolerable to the senses. The list of aroma-producing chemicals used for this purpose is enormous — over 1,500 — and you’ll rarely see the actual chemical name of a fragrance on a label, as many chemicals are grouped together under the umbrella term “artificial fragrance.”
Cancer, nervous system disorders, allergies, and birth defects are some of the shocking concerns that have been linked to artificial fragrance.  It shouldn’t be surprising that an increasing number of public places are now banning their use.
3. Oxybenzone Oxybenzone and avobenzone function in similar ways, and both are found in the majority of commercial sunscreens. While they do absorb the sun’s rays so they don’t penetrate the skin, they are actually more toxic than avobenzone. This chemical may actually be behind the increased rates of melanoma, the skin cancer that most people are attempting to avoid by using sunscreen! Oxybenzone has been found to lower the birth weight of girls whose mothers’ bodies had high exposure levels. It’s also linked to allergies, hormone disruption, and cell damage.   
4. Parabens Parabens are commonly used as preservatives in sunscreen as well as a variety of personal care and beauty products. There are 18 different varieties, and you can easily spot them on most labels because they all contain the word “paraben” in their chemical nomenclature. What makes them dangerous is that they’re estrogen disruptors. Parabens have been associated with infertility, abnormal development of the testes, obesity, asthma, allergies, benign tumors of the uterus or digestive tract, and breast cancer. 
5. Vitamin A Considering that it is a necessary nutrient, it might seem surprising to see vitamin A listed as a concern. The shocking truth is that when vitamin A — often in the form of retinyl palmitate — is exposed to UV light, it creates free radicals that may cause genetic mutations that actually increase cancer risk. Daily use of retinyl palmitate by a pregnant woman may also be toxic to the developing fetus. It has been linked to brain swelling, developmental toxicity, cellular changes, and organ toxicity. Retinyl palmitate produces excess reactive oxygen species which can lead to cell death, and the compound may also be involved in cardiovascular disease. 
The Solution: Organic and Chemical Free Why would anyone who knows of the health risks posed by non-organic sunscreens ever use them? They pose incredible health risks, possibly contributing to the very disease they’re supposed to protect against. The only sane way to protect yourself from the sun’s harmful effects is by using a sunscreen that’s made from natural materials. Please do yourself and your skin a favor by slathering only organic products on your body.
