Having trouble sifting the helpful sunscreen information from the hype? Here are some tips for managing your health in the sun.
Recommended Daily Sun Exposure
Daily sun exposure is critical to the body’s production of Vitamin D, a deficiency which can lead to preeclampsia and cesarean section birth. Yet the skin of pregnant women is more sun-sensitive, and too much sun can incite chloasma. The major takeaway is a recommendation of 15-30 minutes of activity in the sun without sunscreen, outside of peak hours.
Safeguarding Against the Sun
- Year-round sun protection. The sun’s rays aren’t harmful only in the heat of summer. The ultraviolet rays responsible for the harm pose damage every day.
- Peak sun avoidance. The sun’s rays prove strongest and most damaging to skin during the peak hours of 10am and 4pm.
- Wide-brimmed hats. This provides chemical-free sun protection to your scalp, face and upper body. The large brim can create a circle of shade for additional sun safety.
- UVA/UVB sunglasses. Ultraviolet radiation can harm the corneas and lenses of your eyes and may also spur cataract development. Sunglasses specifically marked for UVA and UVB protection should keep your sight safe.
- Sun protective clothing. This is another measure of protecting your skin without the use of chemicals. For the strongest defense, ensure that you wear dark-colored clothing made from thickly woven material.
- Use sunscreen on areas of unexposed skin. Sunscreen works best and most safely when used only on those areas that your hat, glasses, and clothing don’t shield.
Choose a Safe Sunscreen, Part 1: Avoid These Harmful Ingredients
- Vitamin A. Yes, the same vitamin that supports eyesight can corrupt a sunscreen. The EWG found that Vitamin A can become a carcinogen when exposed to sunlight. It has also been linked with birth defects. Vitamin A may take any of the following names on sunscreen labels: retinyl palmitate, vitamin A palmitate, retinol hexadecanoate, and retinol palmitate.
- Oxybenzone. This can disrupt hormones and incite skin allergies. It has also been linked to low birth weight in baby girls.  It’s also known as benzephenone or benzephenone-3.
- Titanium oxide. Scholarship shows that this ingredient is carcinogenic and damages DNA.
- Nanoparticles. The use of nanoparticles in sunscreens prevents the white residue that some products may leave behind. But studies suggest that nanoparticles may be absorbed by the skin, entering the human placenta via the blood-brain or the placental-fetal barrier. 
- Parabens, Fragrance, Other Artificial Ingredients. Like other skincare products, sunblocks can contain harmful ingredients that you want to avoid like parabens and chemicals hidden in fragrance.
Choose a Safe Sunscreen, Part 2: What Makes a Safe Sunscreen?
- Water resistance and full/broad-spectrum protection. Your sunscreen should protection against both types of UV rays. It should also hold up when you enter the waves.
- Non-nanoengineered zinc oxide. This ingredient blocks UV rays safely. When not in the form of nanoparticles, it won’t be absorbed into the skin.
- Creams, NOT sprays. Sprays and powders create unsafe airborne particles of sunscreen. Reapply the cream often.
- SPF between 30 and 50, not higher. Sky-high SPF does not translate to dramatically better sun protection.
- Natural ingredients. Make sure to take a close look at the inactive ingredients as well, looking for a product that uses only natural ingredients to form the base cream of the sunblock, like our Natural Sunscreen SPF 32.
