Sunscreen is considered the holy grale of our skincare regimen as it protects against aging and most important skin cancer. But we’ve been hearing about toxic sunscreens, so what’s the deal?

CHEMICAL VS NATURAL SUNSCREEN
Not all sunscreens are created equally

CHEMICAL
On your label: Oxybenzone, Octinoxate (Octylmethoxycinnamate), Homosalate, Octisalate, Octocrylene, Avobenzone

Chemical UV filters penetrate the skin in order to absorb UV rays. In the process they may enter the bloodstream and can disrupt your hormone system. Hormone disruptors are scary because they’re harmful in small doses, as they mimic the hormones that our bodies create daily and can interfere with everything from our reproductive systems to our metabolism.

NATURAL
On your label: Zinc oxide, titanium oxide

Natural sunscreens are made with the minerals zinc and titanium dioxide. Mineral sunscreens sit on the top of the skin and will help to reflect sunrays away from the skin rather than absorbing them. Zinc oxide and titanium oxide are also said to be the most gentle on sensitive skin. Nothing’s perfect however, they can leave a white cast on your skin. Both protect against UVA & UVB.


UVA & UVB

  • UVA has longer wavelengths and penetrates further into the skin than UVB lights
  • UVA can cause damage in the long run by accelerating signs of aging
  • UVB interacts with a protein called 7-DHC in the skin and converts it into vitamin D
  • UVB can cause visible damage in short-term, by causing sunburn

 

Sunscreen tip: as UVB rays can cause sunburn and UVA can lead up to signs of aging, you want to make sure you are protected against both types of rays.

 

SUNSCREEN ALL DAY EVERY DAY?

Avoiding skin cancer is important, but so is making good Vitamin D. We need the sun to stimulate Vitamin D (especially during winter months). Vitamin D is not only necessary for bone health, but also boosts your immune system and helps to fight depression.


OUR TOP PICKS FROM EWG’S ‘SUN SAFETY TIPS’

  1. Don’t get burned. Red, sore, blistered or peeling skin means far too much sun – and raises your skin cancer risk.
  2. Sunglasses aren’t just a fashion accessory. Good shades protect your eyes from UV radiation that causes cataracts.
  3. Avoid sunscreen with vitamin A. Government data show that tumors and lesions develop sooner on skin coated with creams laced with vitamin A, also called retinyl palmitate or retinol.
