Will it work on gray hair? 

"Thank you for your support to BoSidin. 

BoSidin adopts the same technology as the beauty salon which energy reacts with melanin to generate heat, and makes the hair follicle enter a form of dormancy to some extend and to inhibit hair regeneration. 

Thus, for short and thin villus, BoSidin can solve them all. BoSidin can remove very light hair like grey, white hair which is less than 1 inch, and red, golden hair which is less than 0.5 inch. 

But the melanin content in this very light hair is only 13% of the normal hair, which only has a little reaction with energy. In order to get a better effect, it is recommended that you extend the usage period and stick with it. 

However, the very light hair which is longer than 0.5 inches can rarely absorb enough heat to effectively stop the hair growth as its melanin content is very low. So it is necessary to remove your hair again when visible hair appears in the treatment area, and the minimum interval should not be less than 3 days.

 Since we don't know the specific condition of your hair color, please take a photo of your skin before your purchase, and we will have a professional analyze it for you.

Can the skin appear red and swollen after treatment? 

" Thank you for your support to BoSidin. 

There are two main reasons for skin redness and swelling. First, in order to transfer sufficient energy to the hair follicles for hair removal, most devices use a single pulse. However, the single pulse applied too much energy which may increase the burden of the epidermis. And second, the light waves are not filtered which makes invalid energy stay on the epidermis, and causes damage to the skin, and leads to skin swelling. 

BoSidin adopts the advanced OPT that can filter the invalid bands and promise the energy absorbed by the epidermis will be reduced by more than 95% so that it has no effect on the epidermis. Using Multi-frequency Continuous Pulse Technology, BoSidin makes hair follicles continuously accumulate heat in 10ms of cooling time to inhibit hair regrowth and ensure the safety of the epidermis. 

BoSidin is equipped with 360°Surround Cooling Technology which can protect skin while removing and control the temperature of the epidermis rapidly. 4℃ cooling protective layer is formed on the epidermis during treatment, which promises gentle and effective even on the most sensitive areas of the body.
