What is laser hair removal?
Laser hair removal is a cosmetic procedure that uses a concentrated beam of light (laser) to remove unwanted hair. During the procedure, the laser emits light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or delays future hair growth.
Is laser hair removal permanent?
Laser hair removal typically reduces the number of hairs but does not guarantee permanent hair removal. It usually takes several laser hair removal sessions to provide an extended hair-free period. Periodic maintenance treatments might be needed as well.
What parts of the body can be treated with laser hair removal?
Laser hair removal can be effectively used on almost all parts of the body except the eyelid or surrounding area, due to the possibility of severe eye injury. Common areas treated include legs, armpits, upper lip, chin, and the bikini line. It’s also popular for larger areas such as the back or chest.
How should I prepare for a laser hair removal session?
Preparation for laser hair removal involves several steps:
- Avoiding sun exposure: Protect your skin from the sun for at least six weeks before treatment to avoid complications and enhance effectiveness.
- Lightening your skin: Avoid any form of tanning.
- Refraining from plucking or waxing: Do not pluck or wax the skin for six weeks before treatment as the laser targets the roots of the hair, which are temporarily removed by waxing or plucking.
- Shaving the treatment area: Shaving is recommended the day of or the day before your session. It removes hair above the skin that can result in surface skin damage from burnt hairs, but leaves the hair shaft below the surface intact.
What can I expect during the laser hair removal process?
During the procedure, you’ll be provided with protective eye gear. Depending on the type of laser, a cooling device on the tip of the instrument or a cool gel might be used to protect your skin and lessen the risk of side effects. When activated, the laser will pass through your skin to the hair follicles. The intense heat from the laser beam damages the hair follicles, which inhibits hair growth. You might feel discomfort, like a warm pinprick, and you’ll likely feel a sensation of cold from the cooling device or gel.
Are there any side effects or risks with laser hair removal?
Some typical side effects include skin irritation such as discomfort, redness, and swelling immediately following the procedure. These symptoms typically disappear within several hours. Pigment changes can occur as well, with the treated skin possibly becoming slightly darker or lighter. These changes are usually temporary and more likely in people who don’t avoid sun exposure before or after treatment.
How many sessions are needed for effective hair removal?
Multiple sessions are needed to achieve the best results, typically 8 sessions spaced about four to six weeks apart. The number of sessions depends on various factors, including your hair and skin type, the area of the body treated, and the laser equipment used.
