Simply speaking, photon rejuvenation means that different wavelengths of light are absorbed and acted by different problem skin, which is the simplest explanation I can think of.
The general cost is 4000 to 5000 courses of treatment, and the price of small beauty salons may be lower. The disadvantage is short effective time. If it is whitening and freckle removal, it may take three months to six months, and it will gradually return to its original state. If it is a problem such as acne marks, generally a course of treatment can not completely solve the problem, and it needs to be done many times.
If you are interested, you can try my personal photon skin rejuvenation instrument, called wave luster beauty massage instrument, which can be used every day without side effects. The effect is not worse than that of a beauty salon, but the price is much cheaper than that of a beauty salon.
