How risky is laser hair removal? What are the side effects?

How risky is laser hair removal

The laser process is used to eliminate undesired hair using a focused light beam (laser). Laser hair removal is a simple, inoffensive way to reduce or remove face or body hair permanently. It leaves the skin smoother and silkier than waxing, electrolysis and is a gentle procedure that can successfully treat big regions without any downtime.

A laser generates light during laser hair elimination, which is absorbed via the hair by the pigment. Light power transforms into heat that destroys hair follicles (tube-shaped sacks). This injury prevents or slows the development of subsequent hair.

While laser hair reduction successfully slows long hair growth, it does not generally lead to hair eradication permanently.

What should I do to be ready for laser hair removal?

You should follow the guidelines of the doctor or technician conducting the operation before undergoing laser hair removal.

These might include the following:

  • Trying to stay out of the sun. Avoid sun exposure before and after therapy as directed by your doctor. Apply a broad-spectrum, SPF30 sunscreen every time you walk outside.
  • Skin lightening is a process that involves lightening the color of your skin. Avoid the use of any sunless skin products that darken your skin.
  • Using alternative hair removal treatments as little as possible.
  • Avoiding the use of blood thinners. Before the operation, ask your doctor about any medications you should avoid, such as aspirin or anti-allergic drugs.
  •  It is suggested to shave the day before laser therapy. It eliminates hair over the skin that may harm the surface of the skin.

Pre and During laser treatment

The doctor will apply a hand-held laser device to your skin. To protect your skin and reduce the danger of side effects. Depending on the kind of laser, a cooling device on the top of the instrument or a cool gel is employed. The laser beam will sent through your skin into the hair follicles when the doctor activates the laser.

The intense heat caused by the laser beam destroys hair follicles that impede hair development. You may feel discomfort like a heated pinprick, and from the cooling device or gel, you may feel chilly. It might just take a few minutes to treat a tiny region, like the top lip. It might take more than an hour to handle a larger region like the back.

Post-treatment after laser operation

For the initial few hours following laser hair removal, you may experience redness and swelling. Apply ice to the treated region to alleviate any pain. The doctor may administer a steroid cream to the afflicted region if you experience an effect on the skin right after the laser removes. To avoid irritation and persistent redness do not use harsh sports or hot water/saunas/jacuzzi until 24 hours after treatment. Applying Vaseline or Ointment twice daily to keep the area moist until it heals. Then contacting the office if there are signs of a deteriorating condition in the area.

Risk and side effects of laser hair removal

The elimination of laser hair does not ensure the permanent removal of hair. Although, the new hair growth may be thinner and lighter in color. The risk of adverse effects varies with the type of skin, hair, treatment strategy, and compliance with pre-and post-treatment therapy. The eradication of laser hair works using tiny and high-heat lasers.

After the operation, the laser may produce transient adverse effects. The most frequent adverse effects include skin irritation and changes in pigmentation.

1. Irritation of Skin

This is the main side effect of laser hair removal. After laser removal of the hair, temporary pain, redness, and swelling are likely to occur. Signs and symptoms usually go away in a few hours. They typically have the same results following conventional hair removal, including waxing. In hours after the treatment, overall irritation should diminish. If the symptoms go beyond mild discomfort or if the side effects intensify you should consult your doctor.

Is this treatment painful?. It is common to experience some discomfort throughout the process, particularly in sensitive body areas, such as the aperture. The discomfort is similar to the rubber band flickering on the skin those who attempted the treatment describe. A topical lotion or cooling agent is applying to aid your dermatologist with discomfort and irritation before the operation.

2. Variations in pigmentation

Another side effect of laser hair removal is the appearance of disorder in pigmentation. You may notice that your skin is somewhat darker or lighter after laser therapy. If you have fair skin, you are more prone to get darker patches because of laser hair removal. People with darker skin may have lighter patches due to the treatment. These changes, including skin discomfort, are generally transient and not cause for alarm. Those who do not prevent sun exposure before or after treatment are more likely to have skin whitening.

3. Crusting Effect

Crusting is term as the mixing of pus, blood, or dried sebum with bacterial detritus. Although this is a small issue, it can be inconvenient. If crusting happens, make sure to clean it regularly. It can cause scabbing and scarring if infected. Take good care of the region by hydrating it with light moisturizers to help it recover faster.

4. Discoloration

Complexion discoloration is more likely in those with darker skin, and it can linger for a long time. Make an appointment with a dermatologist who specializes in laser hair removal on all skin types. Avoid excessive sun exposure while recovering since it increases skin pigmentation.

5. Risk Of skin Infection

This is a most irritating side effect of laser hair removal. The practice of destroying hair follicles, like other cosmetic hair removal treatments, might lead to infection. When there are wound-like side effects after the operation, it is critical to get the proper therapy. Only use dermatologist-approved items after therapy.

The affected region of the skin appears to be a wound. As a result, if adequate care is not following throughout the healing time, the laser-treated region may get infected. If you see any symptoms of infection, such as breakouts or fluid leaking from the treated region, contact your doctor right once to avoid further problems.

6. Cause infection In Eye

When utilized on the face, the powerful laser beam used for hair removal can cause eye damage. To avoid any negative effects from lasers on the eyes use proper eye protection.

7.  Cancer-causing

Non-ionizing radiation use in laser treatment in the form of a focused light source that generates a very narrow laser beam. Laser hair removal uses a laser beam to destroy hair follicles (cells from which hair develops), resulting in the loss of hair growth from those follicles. Laser treatment does not employ the same ultraviolet (UV) wavelengths as sunlight that causes damage to DNA in cells and causes skin cancer.

8. Risk of In-fertility

It considers that laser hair removal might induce infertility. Because the lasers only touch the skin’s surface, the limited radiation from the treatment cannot reach any of your organs.


The hairs do not come out immediately, but for days, you will toss them away for weeks. Continued hair growth might be the reason. Hair growth and loss occur in a natural cycle, and laser therapy works best with hair follicles in the new-growth period, so repeated sessions are typically necessary.

In general, laser hair removal for most individuals is safe and efficient. You should not take the treatment close to your eyes or during pregnancy as a precaution. Check with your doctor for uncommon problems following laser hair therapy.
