When people talk about aesthetic devices, they primarily mean high-energy technologies such as lasers, intense pulsed light (IPL), high-intensity focused ultrasound (HIFU), radio frequency (RF), etc., but this unfairly overlooks low-energy therapy. Low-energy devices (referred to as cosmetic devices) are the most widespread in skincare practice. If you understand how they work, they can be used to achieve aesthetic results that are just as significant as those produced by high-energy devices. We created this book to explain how the most popular non-invasive skincare methods - modern low-energy microcurrent, ultrasound (US), and light-emitting diode (LED) therapy - work.

In our book, there are no duty words from leaflets, which you can find in many manual guides for devices. We have collected scientifically valid information about all these methods. Only by understanding how they act can you achieve the best results.

We explain simply and in detail what electricity, ultrasound (US), and light are and how they affect the skin. We discuss which parameters are essential and which are just marketing claims. We tell you what results can be achieved with microcurrent, US therapy and peeling, sonophoresis, and LED therapy, as well as what you should not expect from these approaches and what technologies they should be distinguished from. In addition, we cover the increasingly popular plasma therapy - exposure of the skin to low-temperature plasma (so-called cold plasma). Everything you need to know about these devices and methods to understand them and perform effective treatments is in this book.
