In this study, the skin care system was designed and tested by introducing V-IPL methods that allow various skin treatments. The discharge method, a new method of switching on the flash lamp sequentially according to the lesions, was used.
Pulse shape control is implemented in the system using the conventional LC variable method and the switching mode control method of the switching element. As a result, the pulse width could be varied up to 1㎛ by using a microprocessor, and by turning on the flash lamp sequentially along the lesions along the depth and width, the pulse shape and pulse shape could be more diverse.
We could also make long pulses of up to 1~100[ms] in various pulse widths. And the special differences between the existing system and the proposed system in this study are as follows:
- Existing system : One pulse(pulse width : 1~40ms)
- Proposed system : Three pulse (pulse width : 1~100ms)
In the case of a multi-stage mesh, the pulse width is about 10% and 15% narrower than the first or third stage mesh, but the peak energy is 15%, 5% and the output energy is 17%, 5%, Was higher than the existing system.
As a result, it was found that the V-IPL method, which can be applied to various skin treatments proposed in this paper, is more effective for treating various glands appearing on the skin with two more than three of the existing systems with one pulse.
Future work will be applied to vascular therapy used in pigment therapy, capillary extension, and phototherapy, such as skin aging and facial flushing. And develop an V-IPL system that can be treated with various kinds of skin treatments, such as body hair removal. We also propose that the system is more effective than the existing system through clinical trials.
