Wrinkles, ageing skin, scars …People started to look for ways to fix these aesthetic defects many centuries ago. Ancient people removed the skin’s top layer by using abrasive materials and burned skin with acids obtained from natural products. Modern methods include the use of lasers, microwaves and ultrasound.
However, despite all the diversity of methods and tools, their general approach is the same: burning in order to force the body to regenerate the skin to a somewhat better state than before. And even the simple mechanical removal of the epidermis (that seemingly happens without any sort of heat) aims to burn as well: under the effect of oxygen, tissue oxidises instantly, which is essentially a chemical burn.
Generally, when using any of the traditional methods, the following principle is at work: the more we want to smooth the skin, the more the risk and the pain, and the longer it takes for the patient to recover.
Fractional technologies do not represent a genuinely new mode of laser action. An ordinary laser can be transformed into a fractional laser by simply adjusting computer settings. The risks of adverse effects can only be reduced, but not absolutely eliminated. The very concept of rejuvenation through thermal or chemical burns appears to be quite disputable.
How can we force the body to regenerate without creating thermal or chemical burns? Is the way likely to be found?
