What’s in your Sunscreen?

There are two forms of sunscreens on the market today, chemical and mineral.

Mineral Sunscreens
Mineral sunscreens use zinc oxide and/or titanium dioxide.
This creates a physical barrier that protects your skin from the sun.

Chemical Sunscreens
Most sunscreens we see on the shelves promise to protect you from UV rays, be long lasting and are waterproof. What you may not know is that most sunscreens contain many chemical ingredients that are toxic to the body. These ingredients can be detected in blood, breast milk and urine samples.

Active ingredients found in chemical sunscreens:
oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate.

According to the Environmental Working Groups website, lab studies showed that these ingredients, may mimic or disrupt hormones or cause skin allergies. There have been studies and research on three common UV filters in sunscreens, oxybenzone, homosalate and octinoxate. The studies indicated that when applied to areas of the body it appeared to disrupt hormones and be an endocrine disrupter.
If that’s not bad enough, there are inactive ingredients in sunscreens that are harmful as well. The inactive ingredients make up 50% to 90% of sunscreens.

Inactive Ingredients found in Chemical Sunscreens
The most notable Ingredient to be aware of is methylisothiazolinone or MI. It’s a preservative and it is used in sunscreens and in daily moisturizers with SPF. It can be used alone or with another perseverative called methylchloroisothiazolinone or MCI. In 2013, the American Contact Dermatitis Society named MI its “allergen of the year”. Lab studies have shown that MI and MCI can induce an allergic response following skin contact. Yet these chemicals are widely used in sunscreens and daily moisturizers.

Be Safe this Summer

Many sunscreens provide a false sense of security when it comes to sun exposure and can do more harm than good. Try to avoid using most chemical sunscreens, especially spray on sunscreens. We stongly recommend using a Mineral Sunscreen, like our Face Shade or our Sun Shade (coming soon).

DISCLAIMER: This blog post is to inform you ( the reader ) of  the potential dangers of chemical sunscreen. While you should exercise caution in sun exposure (and overexposure), you should also be aware of what you’re putting onto or into your body.
