While estheticians are commonly asked to recommend natural and safe sunscreens, it's first crucial to understand why vitamin D is so important to our body and skin as well as safe ways of getting it from the sun. It's a constantly evolving subject, and esthetics professionals need to stay informed.

We know that the most effective means of producing vitamin D (a hormone) is through sun exposure, but it's also acquired through dietary supplements and certain foods.

Why do we need Vitamin D?

  • Regulates calcium and phosphorus levels, and strengthens teeth and bones, to prevent osteoporosis
  • Strengthens immune response by stimulating T-cells that respond to viruses, bacteria, and other pathogens. Research shows that Vitamin D also reduces the severity of COVID infections.
  • Improves brain function by controlling the production of neurotransmitters and aiding nerve growth and repair. 
  • May reduce the severity of autoimmune disorder symptoms, by reducing inflammatory processes.
  • Regulates serotonin levels in the brain, providing a natural remedy for mood disorders like seasonal depression.
  • Plays a protective role in reducing the risk of skin cancer.
  • Regulates the production of healthy sebum and lipids, a vital protective layer on the skin.
  • Maintains a healthy microbiome by controlling the growth of keratinocytes into corneocytes, cells in the outer layer of your skin. They act like a shield against pathogens and keep skin hydrated by preventing transepidermal water loss (TEWL).
  • Anti-inflammatory for the skin, improving symptoms of psoriasis and eczema.

Becoming Sun Smart

A little bit of sun exposure is enough to meet your body's need for Vitamin D.

  • Head outside for 5-20 minutes of sunlight in the morning or late afternoon (any time your shadow is longer than yourself!), and your body can synthesize enough Vitamin D to provide the benefits mentioned above.
  • Wear protective clothing in the hottest parts of the day, including a hat and sunglasses.
  • Stay in the shade when the sun is at its strongest, between 10 am and 4 pm
  • If you're going to be out in the sun in the hottest parts of the day, or have lengthy exposure, choose an effective and safe sunscreen by looking for products that include Micronized Zinc Oxide, or Titanium Dioxide.

Should you avoid chemical sunscreen?

A study published in the Journal of the American Medical Association (JAMA) has shown that ingredients in chemical sunscreens (such as oxybenzone and octinoxate) can be absorbed into the bloodstream and have been linked to hormone disruption. The study found that levels of these chemicals in the bloodstream can continue to increase even up to 24 hours after application, with the effect being enhanced by reapplication of sunscreen.

While we don't know a lot about the long-term health effects of these chemicals, the study has raised concerns about their potential impact on our health. 

What to recommend to your clients?

L'Moor follows the philosophy that "when in doubt, leave it out", and we don't sell products that contain chemical ingredients of concern. We do like to focus on sun protection products that contain micronized
Zinc oxide and titanium dioxide, and wax-coated zinc oxide vs. coated nanoparticles (which contain plastics).
