Are You Sensitive to Sunscreen?You don't need to be sun-phobic, but you do need protection from overexposure to the sun's ultraviolet (UV) rays because they can cause long-term damage to the skin, accelerate aging, and greatly increase your risk for development of skin cancer.1 However, many people are so sensitive to the effects of sunscreen chemicals that they're going without sunscreen (which I don't recommend). Remember, some sun is good for you. Sunlight on your skin is one of the few ways your body is able to make vitamin D. A loose, general rule is to get 10-20 minutes of sun (on your arms, and legs if possible) three times a week (where and when possible) but do apply sunscreen after the first few minutes to avoid UV damage.2 This is a very general rule, however, as the paler your skin type the more easily your skin can produce vitamin D. It also depends upon how close you live to the equator, the time of day, and the amount of skin exposed.3

Chemicals in Sunscreen

Most sunscreens contain lanolin (wool alcohols), fragrances and preservatives, as well as certain chemicals which block or absorb the sun's harmful UV rays. These chemicals can disturb sensitive skin and cause allergic contact dermatitis and, in some cases, photocontact dermatitis.4 However, there are far more serious concerns about sunscreen chemicals that include xenoestrogens (chemicals that mimic estrogen), hormone disruption, links to endometriosis, and sprem and thyroid alterations in animal studies.

Here is a list of of common sunscreen chemicals in order of toxicity:

Highest Toxicity

  • Oxybenzone (linked to endometriosis, mimics estrogen, alters sperm production in animal studies)
  • Octinoxate or Octyl methoxycinnamate (hormone-like activity, reproductive system, thyroid alterations in animal studies)

Moderate Toxicity

  • Homosalate (hormone disruptor)
  • Octisalate
  • Octocrylene

Lower Toxicity

  • Zinc Oxide
  • Avobenzone
  • Mexoryl SX
  • Titanium Dioxide5

Sensibly Protecting Yourself In the Sun

  • If you're planning to stay out in the sun for more than 10-15 minutes and cannot tolerate sunscreen, wear long pants or a skirt, long sleeves and a hat.
  • Limit your time in the sun, and try to avoid going out when the sun's rays are the strongest (10:00 a.m. - 2:00 p.m.)
  • Wear a broad-spectrum sunscreen.6

How to Buy Safe Sunscreen
