Laser Hair Removal Machine

During the procedure

laser hair removal machine, The doctor will press a hand-held laser instrument to your skin. 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 the doctor activates the laser, the laser beam 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, such as a warm pinprick, and you'll likely feel a sensation of cold from the cooling device or gel.

Treating a small area, such as the upper lip, might take only a few minutes. Treating a larger area, such as the back, might take more than an hour.

After the procedure

You might notice redness and swelling for the first few hours after laser hair removal.

To reduce any discomfort, apply ice to the treated area. If you have a skin reaction immediately after laser hair removal, the doctor might apply a steroid cream to the affected area.

After laser hair removal and between scheduled treatments, avoid sun exposure — both natural sunlight and tanning beds — for six weeks or as directed by your doctor. Use a broad-spectrum sunscreen daily.

Results

Hairs do not fall out immediately, but you will shed them over a period of days to weeks. This may look like continued hair growth. The repeated treatments are usually necessary because hair growth and loss naturally occur in a cycle, and laser treatment works best with hair follicles in the new-growth stage.

Results vary significantly and are difficult to predict. Most people experience hair removal that lasts several months, and it might last for years, but laser hair removal doesn't guarantee permanent hair removal. When hair regrows, it's usually finer and lighter in color.

You might need maintenance laser treatments for long-term hair reduction.
