When talked about hair removal machine, most of people will mention the IPL, OPT, or 808nm diode laser, but what’s the main difference between them? And how we choose the best one? Here let’s see the difference and main functions.
It is generally believed that hair removal is based on the principle of selective photolysis, melanin cells in hair follicles can absorb a specific wavelength of light. OPT, that is Optimal Pulse Technology, used strong pulse light of broad spectrum 610-1000nm , adjustable wide range of pulse width, usually it takes people 8-9 treatment times and can permanently remove unwanted hair from different body parts of different colors. With different filter, OPT can achieve both hair removal and skin rejuvenation functions, it’s the most traditional way for hair removal and widely used by most people for a long time.
As for 808nm diode laser, it used the selective 808nm diode laser and the laser goes through the skin surface to reach the root of hair follicles, light can be absorbed and converted into heat damaged hair follicle tissue, so that hair loss regeneration without injury surrounding tissue. It’s the most advanced technology with slight pain, easy operation, the most safe, technology for permanent hair removal now. Remove unwanted hair within only 3-4 times treatment, which equals to 3-4 times traditional way, but with high price.
Anyway, both of two ways are with great function, popularly used by many customers, OPT is the traditional way but most economical, 808nm diode laser will be more effective and safe, but more expensive, which one do you prefer? I think it depends on your choice.
