Tanda Zap is my first real experience with light therapy and I have to say that so far I'm impressed. The Tanda Zap is a bit different than other at home LED therapies. First, it is a targeted spot treatment. Second, it isn't only light. It also incorporates heat and sonic vibration. I guess to shake the pimple out of your skin?
The hand held device is about the size of a C battery, but longer. Why is this my point of reference? Because every baby item in my house runs on C batteries. We should all buy stock in Duracell. Anyways, it is pretty small and lightweight. At one end there are little plastic bumps, and this is where the light comes out of. When I turn it on there is a very light vibration, though it isn't very obvious. The end lights up blue, and after about a minute it is faintly warm. The entire treatment lasts about 2 minutes and should be performed about 2-3 times a day on affected areas.
I was going to do a little info on how the blue light works. But then I found that over at Future Derm you can read Nicki's little summary as she's already done a more scientific sounding overview than I would have done. The bottom line is the blue light affect P. Acnes, the bacteria responsible for acne, and after a little while the bacteria basically self implodes. The light should work for pretty much any type of acne except for cystic, which is not recommended as it may be extra painful.
The light bulb works for about 10,000 uses, but once it is used up you'll need a new Tanda Zap. Considering it only costs $50, I think this is less expensive per use than any of the over the counter acne spot treatments.
So, after all of that, does this little gizmo actually work??? I think it does. Now that I only have sporadic outbreaks, I've been in the market for a spot treatment that works and doesn't dry out the surrounding skin. The Tanda Zap is my answer. I've had a few blemishes over the last several weeks, and they have all resolved in less than 12 hours after being exposed to the Tanda Zap once or twice. Seriously. For realz. The pimple is completely gone, and all I did was hold this little blue light over it for a few minutes.
I'm telling all of my friends to get one.
