For the past two weeks we have been studying electricity and its applications for skin. It’s ranged from pretty boring–anyone want to give me the dictionary definition of plug–to downright fascinating. The beauty-speak of ions and electrolytes meant nothing to me all these years–it was just jargon to make something SOUND impressive. But, electricity does have meaning to the body and the skin. Electrolytes, which are made up of ions, regulate the pH levels of the body, and they are extremely important in hydration (this is where osmosis comes in–making sure intracellular and extracellular fluids are balanced). They also play a role in the body’s muscular and nervous systems (which I will be covering in a few weeks).

In terms of beauty treatments, some are more effective than others but each serves a certain purpose and it is not simply snake oil. High frequency machines are germicidal, and perfect for zapping acne post-extractions (to keep post-facial breakouts from occurring). Galvanic currents help with product penetration. Faradic currents (such as those silly “shock” belts that you see on info-mercials that tout a no-exercise solution to weight loss) actually DO exercise the muscles, thereby increasing muscle tone, but you have to use them daily to see any sort of results.

I get to play with some of the machines at school tonight! Fun!
