Rarely, laser hair removal can cause blisters, crusting, scarring, or other changes in skin texture. Other rare side effects include greying of treated hair or excessive hair growth around treated areas, especially on darker skin. The laser hair removal process works by using small, high-temperature lasers that can cause temporary side effects immediately after the procedure. Skin irritation and changes in pigmentation are the most common side effects.
The laser hair removal process isn't usually painful, but the skin may ache or feel sensitive afterward. The side effects of laser hair removal can also include irritation, changes in skin color, crusting, and more. In some cases, hair may be seen to grow back after laser treatment for a few months to a few years. Initially, hair may regrow 4 to 6 weeks after laser therapy. However, after a consistent treatment of 4 to 6 sessions, you may need a touch-up every 6 months or every year to avoid having a beard.
The hair that grows back in the laser-treated area is actually thinner and thinner. The laser damages or destroys the hair follicles in which the hair grows. Therefore, effective laser hair removal therapy cannot cause denser growth in the treated area. Actually, there should be about a 10 to 25% reduction in hair growth after each laser therapy session. Laser therapy can only destroy hair that is in the growth phase, and not the one that is dormant inside the follicle.
Within a few days of therapy, inactive hair will begin to grow actively. Therefore, a minimum of 4 to 6 sessions, spaced out over a few weeks, are required to destroy all the hair in the target area. However, the number of sessions you need will depend on several factors such as hair type and growth rate. That's why many people opt for permanent hair removal and laser treatments to remove unwanted body hair. Laser therapy involves the use of advanced equipment that allows you to achieve the desired results of hair removal. Therefore, it makes sense to plan laser hair removal after you have given birth and finished breastfeeding.
According to a study on the effects of laser hair removal in groups of diverse ethnic backgrounds, the number of treatments and the severity of side effects are interrelated. However, this radiation is not thought to be harmful and there is no evidence that laser hair removal therapy causes skin cancer. For most people, laser hair removal is a safe way to remove unwanted body hair permanently or for extended periods. Before starting therapy, people should be aware of some side effects of laser hair removal as well as some myths surrounding the process. It may take several treatments to completely remove unwanted hair and permanent hair removal isn't always guaranteed. However, current advances in laser technology have made it possible for laser hair removal to be available to people of all skin types and colors. Naturally or artificially tanned skin can make laser hair removal less effective and cause side effects.
But because most hair follicles are damaged, hair doesn't grow for an extended period of time. Your doctor may recommend other options since laser hair removal usually requires several sessions that should not be done during pregnancy. The lasers used in this treatment only remove hair and do not penetrate the skin or affect any other organ in the body.
