There are so many laser hair removal devices on the market, which one is easy to use and worth recommending? Let’s analyze the use of laser hair removal devices with LEFIS, and you will naturally know how to choose a laser hair removal machine.
Laser hair removal is a medical method that uses a spotlight (laser) to remove unwanted hair.
During laser hair removal, the light beam emitted by the laser is absorbed by the pigment (melanin) in the hair. The light energy is converted into heat, which destroys the tubular follicles (hair follicles) in the skin that produce hair. This damage can inhibit or delay future hair growth.
Although laser hair removal can effectively delay hair growth for a long time, it usually does not remove hair permanently. Initial hair removal requires multiple laser hair removal treatments and may require maintenance treatments. Laser hair removal is most effective for light-skinned, dark-haired people, but can be used successfully on all skin types.
Laser hair removal can be used to reduce unwanted hair. Common treatment sites include the legs, armpits, upper lip, chin, and bikini line. However, excess hair can be treated almost anywhere except the eyelids or the surrounding area. Laser hair removal should also not be done on tattooed skin.
Hair color and skin type can affect the success of laser hair removal. The basic principle is that the pigment of the hair (and not the pigment of the skin) should absorb light. The laser should only damage the hair follicles while avoiding damage to the skin. Therefore, the contrast between hair and skin color (dark hair and light skin) will produce the best results.
The risk of damage to the skin is greater when there is little contrast between the color of the hair and the skin, but advances in laser technology have made laser hair removal an option for people with darker skin. Laser hair removal is less effective for hair colors (grays, reds, blondes, and whites) that don’t absorb light well. But laser treatment options for light-colored hair continue to be developed.
The risks of laser hair removal
The risk of side effects varies with skin type, hair color, treatment plan, and compliance with pre- and post-treatment care. The most common side effects of laser hair removal include:
Skin irritation. Temporary discomfort, redness, and swelling may occur after laser hair removal. All signs and symptoms usually disappear within a few hours.
Pigment changes. Laser hair removal may darken or lighten the affected skin. This change may be temporary or permanent. Skin lightening mainly affects those who did not apply sunscreen before and after treatment as well as those with darker skin tones.
Rarely, laser hair removal can cause blisters, scabs, scarring, or other changes in skin texture. Other rare side effects include graying of the treated area and excessive hair growth around the treated area, especially with darker skin.
Laser hair removal is not recommended for use on the eyelids, eyebrows, or surrounding areas, as serious eye damage may result.
What to do before using the laser hair removal machine
If you are interested in laser hair removal, choose a doctor who is certified in a specialty such as dermatology or cosmetic surgery and has experience with laser hair removal for your skin type. If a physician assistant or licensed nurse will perform this procedure, be sure to perform the treatment under the direction of your doctor and be present during the procedure. Be careful when choosing spas, salons, or other establishments that allow laser hair removal by non-medical personnel.
Before laser hair removal, check with your doctor to determine if this treatment option is right for you. Your doctor may do the following:
Review your medical history, including medication use, history of skin disease or scarring, and past hair removal procedures
Discuss the risks, benefits and expectations, including what laser hair removal can and cannot achieve for you
Photographs for pre- and post-operative evaluation and long-term review
During the consultation, discuss the treatment plan and associated costs. Laser hair removal is usually at your own expense.
The doctor will also provide specific instructions on how to prepare for laser hair removal. May include:
Avoid sun exposure. Before and after treatment, avoid sun exposure as advised by your doctor. Wear broad-spectrum SPF30 sunscreen every time you go out.
Whitens skin. Avoid using any lotion for sunless skin tanning. If your skin has recently been tanned or your skin has darkened, your doctor may also prescribe a skin bleaching cream.
Avoid other hair removal methods. Hair plucking, waxing, and electro-hair removal can interfere with hair follicles and should be avoided for at least four weeks before treatment.
Avoid blood thinners. Before surgery, talk to your doctor about which medications to avoid, such as aspirin or anti-inflammatory drugs.
Shave the treated area. It is recommended to trim and shave the day before laser treatment. This removes body hair from the surface of the skin, which could otherwise cause damage to the skin surface, but leaves the hair shaft intact below the surface.
what you can expect
Laser hair removal usually requires 2 to 6 treatments. The interval between each treatment will vary by site. In areas with rapid hair growth, such as the upper lip, this treatment can be repeated in four to eight weeks. In areas with slow hair growth, such as the back, treatment may be given every 12 to 16 weeks.
You will need to wear special goggles to protect your eyes from the laser beam for each treatment. If necessary, the assistant may shave the irradiated area again. Your doctor may apply local anesthesia to the skin to reduce discomfort during treatment.
Your doctor will press a handheld laser against your skin. Depending on the type of laser, a cooling device or cold gel at the tip of the instrument can be used to protect the skin and reduce the risk of side effects.
When the doctor activates the laser, the laser beam will travel through your skin to the hair follicles. The intense heat from the laser beam damages the hair follicles, inhibiting hair growth. You may experience discomfort at this time, for example, feeling hot, tingling, cooling devices or gels that can give you a cold feeling.
Treatment of small areas, such as the upper lip, may only take a few minutes. Treatment of larger areas, such as the back, may take more than an hour.
Symptoms of redness and swelling may occur within a few hours after laser hair removal.
To reduce discomfort, apply ice to the treatment area. If a skin reaction occurs immediately after laser hair removal, your doctor may apply a steroid cream to the affected area.
After laser hair removal and during scheduled treatments, avoid direct sunlight and avoid using tanning beds for 6 weeks or as directed by your doctor. Use a broad-spectrum sunscreen with SPF30 daily.
The hair will not fall out immediately, but will fall out within a few days to a few weeks. It looks like the hair continues to grow. Repeated treatments are usually necessary because hair growth and shedding occur naturally in a cycle, and laser treatment works best on nascent stage hair follicles.
The results vary widely and are difficult to predict. Most people go through a process of hair loss that lasts for months, maybe even years. But laser hair removal does not guarantee permanent hair removal. When the hair regrows, it is usually finer and lighter in color.
What about home lasers?
You can use laser hair removal at home. These devices may cause hair loss. However, there are no large studies comparing these devices to laser hair removal performed in a doctor’s office.
Additionally, the FDA considers these at-home laser hair removal devices to be cosmetic, not medical devices, meaning they are not inspected to the same level as other medical devices. Currently, there are no large, long-term studies on the safety and efficacy of home machines.
If you choose to use a home laser hair removal device, follow the instructions that came with the device to help reduce the risk of injury, especially to the eyes.
To have a good hair removal effect, it is recommended that you use a more professional laser hair removal device, which is safe and secure.
