Have you heard that there is a new sunscreen you can drink? Sometimes things that sound too good to be true are exactly that.
Osmosis Skincare’s UV Neutralizer Harmonized Water is a product that claims to provide the equivalent of SPF 30, protecting you from 97% of UVA and UVB rays for up to three hours. How? By "making the water molecules just below the surface of your skin vibrate, emitting frequencies that cancel out the burn-causing frequencies of UVA and UVB radiation." This is according to Ben Johnson, MD, general practitioner and founder of Osmosis Skincare.
Say what? As far as I know, there is no technology that would allow water molecules to vibrate via anything one would ingest. Nor can I conceive of any principle of physics whereby vibrations could interfere with ultraviolet light.
Dr. Johnson concedes that no controlled or randomized trials have been performed. He apparently has had roughly 50 patients try it and feel that it helps.
Until he explains the science and performs studies that show efficacy, I would recommend one not rely on this product to prevent sunburn. My concern is that people might try this and get a severe sunburn which could greatly increase their risk for a potentially fatal melanoma.
But hey, that's just my opinion.
Recent studies suggest that we need not be concerned about nanoparticles in sunscreens. Researchers assessed exposure by the extent of nanoparticle zinc oxide (ZnO-NP) contained in sunscreens and other cosmetic products and found that the level of exposure and penetration is not sufficient to affect cell function, including metabolic state of skin cells or their morphology.

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.
