Take Shobha, for instance. The NYC-area hair removal salon offers a lemon-based sugaring gel that's actually OK to eat. In fact, I'm told it makes excellent margaritas thanks to its able-to-be-consumed components of sucrose, water, glycerin, and citric acid.
A similar notion rings true for the herbalists at Vivoderm. The brand's antiacne mask helps to soothe and treat pimple-prone skin, but due to a natural blend of rosemary, marshmallow, mint, fennel, and basil (among others), this green powder can be ingested, too. (This one might be more of an acquired taste, though.)
The go-natural movement may not be new, but perhaps we'll be seeing an increasing number of companies take on the "you are what you eat" mantra in terms of cosmetics. Whatever the case, it brings a whole new meaning to looking delicious, no?
