Developed by Osmosis Skincare, the Harmonized H20 UV Neutralizer drink allegedly blocks 97 percent of harmful UVA and UVB rays from the sun.
"Achieve UV 30 protection before the sun even hits you with our innovative new technology that isolates the precise frequencies needed to neutralize UVA and UVB," according to the product's website.
The Harmonized H20 drink, which is available in Tan Enhancing and No Tan Enhancing varieties, supposedly causes molecules on top of the skin to vibrate and prevent over-exposure to the sun.
"It's just a gimmick," Dr. Rang Singh told the Daily Telegraph. "We know that ingestible sun products aren't that good. To say they have changed the frequency of water molecules, well I just don't understand how they could have done that."
Harmonized H2O sells for $30 and can be purchased online.
"Everything in our body vibrates at its own frequency anyway and, as far as I know, nobody has found a way to change that," Singh said. "I wouldn't just take these claims with a pinch of salt, I would take them with a fistful."
