Once you undergo an IPL treatment, you should know that your hair won't be gone immediately afterward. While this treatment does destroy the hair follicle , the hair shaft still needs to shed. This process typically takes about two weeks. Once that final hair falls out, another one will never grow again.
After IPL hair removal The hair will appear to grow (though very slowly) for 2 to 4 weeks and should then fall out ; this is the treated hair being pushed out of the follicle, not new growth. Any hair that does not fall out was either too fine, too light, too deeply rooted or possibly wasn't treated.
Answer: Yes it is possible but very rARE in very rare cases IPL can cause increased facial hair growth. It is more likely to happen when treating darker skin types and using low energy. Some patients with hormonal imbalances might notice more facial hair after the IPL, but again it is very rare.
Well no, not necessarily . Laser is in fact simply a stimulated emission of light that has been amplified. In the case of hair removal, the light from both laser and IPL is used to destroy your hair follicles by heating up the melanin in them. Melanin is responsible for the pigmentation in your hair and skin.
