In this article we answer the question “how does laser hair removal work”.
What is laser hair removal and how does it work?
Laser hair removal is a process that uses a laser beam to remove unwanted hair on the body. During the treatment, the laser targets the pigment in the hair follicle, emitting a concentrated beam of light that damages and eliminates the follicle, preventing future hair growth. Laser hair removal is effective on most areas of the body, but works best on dark hair and light skin. It is important to note that the treatment may cause some discomfort, but can be managed with topical anesthetics. Multiple treatments over several weeks are necessary to achieve desirable results.
Is laser hair removal safe and who is a good candidate?
Yes, laser hair removal is safe when performed by a licensed and experienced provider. Good candidates for laser hair removal include individuals with dark hair and light skin, as the laser targets darker pigments in the hair follicles. However, advancements in technology have made laser hair removal viable for individuals with different skin tones and hair colors. It is important to avoid sun exposure before and after treatment and to follow post-treatment care instructions to minimize potential side effects, such as temporary redness and swelling. Consult with a dermatologist or licensed laser hair removal provider to determine if laser hair removal is right for you.
How effective is laser hair removal and how long does it last?
Laser hair removal is an effective way to reduce hair growth, targeting hair follicles with laser energy to prevent hair regrowth. The treatment can last from a few months to several years, depending on each individual’s hair growth cycle. Most people experience permanent hair reduction, although some hair may regrow over time. It is important to note that results may vary depending on factors such as skin type, hair color, and medical conditions. Multiple treatments are necessary for the best results, with sessions spaced several weeks apart to ensure proper treatment of all hair follicles.
What should I expect during a laser hair removal session?
During a laser hair removal session, you can expect to feel a tingling or stinging sensation as the laser targets hair follicles. The laser produces a beam of highly concentrated light that is absorbed by the melanin in the hair, damaging the follicle and preventing future hair growth. The procedure is usually quick and can treat multiple hairs at once. You may need several sessions for optimal results, spaced several weeks apart to allow hair to shed naturally. Before your session, you will need to avoid tanning and shaving, and protect your skin from the sun afterwards.
How many sessions are required for optimal results?
The number of sessions required for optimal results in at-home laser hair removal treatment may vary depending on various factors, such as hair thickness, the treated area, and skin color. Usually, it takes around 6 to 8 sessions spaced 4 to 6 weeks apart to achieve optimal results. The laser targets and destroys the hair follicles that are in the active growth phase during the treatment. Since not all follicles are active at the same time, several sessions are necessary to target all follicles. Practicing good skin care routine and avoiding sun exposure during and after treatment can also help achieve best results.
Does laser hair removal hurt and how do I prepare for a session?
Before a laser hair removal session, it’s important to avoid sun exposure and stop using any products that can irritate the skin, such as exfoliants and retinoids. It’s also recommended to shave the area being treated before the session. The laser itself may cause some discomfort, described by some individuals as feeling like a rubber band snapping against the skin. However, many people find the discomfort to be tolerable, and numbing creams can be applied beforehand to help reduce any pain. After the session, the treated area may be red and sensitive, but this typically resolves within a few hours.
Are there any side effects or risks associated with laser hair removal?
While laser hair removal is generally safe, there are potential side effects and risks associated with the treatment. These can include temporary discomfort, redness, and swelling of the treated area. Rarely, laser hair removal can cause blistering, scarring, or changes in skin pigmentation. There is also a small risk of eye injury if proper eye protection is not used during the treatment. However, choosing a licensed and experienced provider, following proper pre- and post-treatment care instructions, and using proper eye protection can minimize these risks. It is important to thoroughly discuss any concerns with your provider before undergoing laser hair removal.
