What You Need To Know About Summer Sun Safety

What we know for sure about sunscreen

  • It is really good at preventing the feared sunburn when applied as recommended.
  • Decreases the appearance of sun spots a.k.a. solar keratosis.

What we think that we know

  • Appears to diminish the occurrence of squamous cell carcinoma, which is a slow growing and treatable skin cancer.
  • Doe not seem to impact basal cell carcinoma.
  • Sunscreen seems to reduce our capability to produce vitamin D. We currently have a Vitamin D deficiency pandemic.

What confuses the hell out of us

  • Some studies report higher incidence while other studies report lower incidence of the deadliest kind of skin cancer, malignant melanoma, among frequent users of sunscreen. This is most likely due to increase exposure to UVA in spite of adequate UVB sunscreen protection.
  • It's easy to be disorientated when the medical specialties advise counter each other.

The American Medical Association recommends 10 minutes of unguarded daily sun exposure for vitamin D production.

The American Academy of Dermatology states there isn't any scientifically certified, safe threshold level of UV exposure from the sun that allows for adequate vitamin D synthesis without inflating risk of skin cancer.

What you should do about it

The best protection is physical protection like protective clothing, hats and shades which defend you from the damaging impact of ultraviolet-A rays on your skin without any dangerous chemicals. Staying out of the sun during peak times and looking out for a shady environment is also key to your safest defense. Sunscreen should really only be considered when doing the previous suggestion is unavoidable. The environmental working group recommends mineral cream based sunscreens containing zinc or titanium dioxide as they have very little skin absorption. If mineral based sunscreen cannot be used avobenzone or mexoryl Sx seem like the subsequent surest bet.

Sunscreens to avoid

  • Oxybenzone: Found in sixty percent of sunscreens. It's known to penetrate the skin, it is truly absorbent and a potential hormone disruptor.
  • Vitamin A (retinyl palmitate) : Preliminary but replicable research has shown it to be photocarcinogenic- carcinogenic once exposed to ultraviolet light. Vitamin A is found in over 41% of all sunscreens on the market despite these discoveries.
  • Sprays and powders should be avoided due to worry of lung inflammation when inhaled.

Check out how safe the sunscreen you currently use is at the environmental working group sunscreen database. An iphone widget isavailable.
