Laser hair removal is designed to reduce future hair growth by utilizing focused light to target and disrupt hair follicles permanently.
The laser’s intense light is absorbed by the pigment in the hair, which heats up and damages the hair follicles permanently. This damage inhibits or delays future hair growth, providing a more permanent solution to hair removal compared to other methods.
The frequency of needing to shave or wax is reduced, benefitting those with a busy lifestyle or for whom regular hair removal is a cumbersome task. Less time and money is also spent on razors, creams, or salon visits.
There is a reduced occurrence of ingrown hairs commonly associated with shaving or waxing. Targeting the hair at the root prevents the typical scenario where cut hairs grow back into the skin, leading to painful and unsightly ingrown hairs.
Laser hair removal removes hair from the root and prevents the rough stubble commonly associated with cut hairs. The laser targets the hair follicle, leading to a smoother, more consistent skin texture. The hairs that regrow are also finer with time.
Laser hair removal is typically less painful compared to other methods like waxing. Most patients describe the sensation as a quick snap of a rubber band against the skin. Modern laser technologies also incorporate cooling mechanisms that minimize discomfort during the procedure.
The procedure requires multiple sessions, each with higher upfront costs, making it more expensive compared to traditional methods like shaving or waxing.
Some patients may experience temporary skin irritation, including redness, swelling, and mild discomfort caused by the heat generated by the laser targeting the hair follicles.
Side effects are generally temporary and can be managed with proper aftercare, such as applying a cold compress to the area targeted by the treatment.
The laser targets the melanin in the hair, causing laser hair removal to work best on dark hair against fair skin as the laser can easily differentiate between the hair and skin. For individuals with darker skin or lighter hair, laser hair removal may not be as effective in eliminating hair growth.
When not performed correctly, laser hair removal can lead to skin damage, such as burns, scars, or pigmentary changes on the skin. Seek laser hair removal treatments performed by qualified and experienced professionals and laser practitioners, particularly for those with darker skin tones.
