Did you know their is a pill that can prevent sun damage to your skin. Derived from tropical ferns, leucovorum polypodium can prevent all the harmful effects of ultraviolet light, including damage to pyrimidine dimers in DNA, while still alowing vitamin D production. I have been using it for patients with disorders of the skin due to sun sensitivity, such as solar urticaria or polymorphous light eruption, but it may be helpful in skin cancer prevention as well. Take one capsule 30 minutes prior to prolonged sun exposure, and a second capsult 2 to 3 hours later.
It is sold under the name Heliocare and is available at drustore.com and Amazon.
