The days of asking a friend to rub suncream on your back or waiting for your lotion to "sink in" to avoid a sandy situation could be numbered, as a US skincare company claim to have created a drinkable suncream.

Osmosis Skincare claim their product, named Harmonised H20 UV protection, can provide sun protection up to factor 30. Those who make the product, which is available to buy, claim that once the elixir is ingested, molecules of the product vibrate on the skin to cancel out 97 per cent of UVA and UVB rays.

Harmonized H20 is said to provide sun protection

The website of the company, which was founded by Dr Ben Johnson, advises people to take 2ml of the liquid every four hours while in the sun, preferably with water, to achieve the full protection. The website unsurprisingly lists many testimonials but the product is yet to be endorsed by official dermatologist bodies.

The product retails at $30 (£17) for a 100ml bottle and it comes in two forms – "tanning" and "non tanning", the former allowing users to achieve a tan while being protected from harmful sun rays.

Drinkable cosmestics are a new frontier for the beauty industry, following a surge in edible products in recent years. Recently developed products include skin enhancing gummy bears. Skincare supplement company Imedeen already offer a Tan Optimizer Capsule, promising to enhance tan, although without SPF protection. Sue Devitt, a make up artist to stars including Sarah Jessica Parker, was one of the first to develop a drinkable beauty elixir.

The development of drinkable SPF comes at a time when standard suncreams are being questioned about the level of protection they provide by consumer watchdogs.
