How Long Does Laser Hair Removal Last? Side Effects of Laser Hair Removal.

How long does laser hair removal last?

Laser hair removal is a non-invasive, cosmetic method done to remove unwanted hair from the face and body. For some people, laser hair removal on the body supplies permanent or near-permanent outcomes. Others may see a large depletion in the amount and thickness of hair that reincreases over time.

While permanent outcomes are not normally achieved on the face, reincrease may not occur for years. Outcomes may vary and depend on many factors. However, these may include the areas being cured and fluctuating hormonal levels.

How long before hair starts to grow back?

To decide how long it will take before your hair increases back may support understanding the growth pattern of hair.

Stages of hair growth

Hair goes between four stages of growth, They are:-

  • Anagen, the increasing phase
  • Catagen, the intermediate phase
  • Telogen, the resting phase
  • Exogen, the shedding phase

At any given period, you have hairs going between all four phases. Laser hair removal works by demolishing existing hairs under the skin and at the root. For that reason, it can only target hairs throughout the anagen or increasing phase. That’s why it uses multiple cures, spaced apart, to get to all of the hair that increases in a particular spot.

Regrowth on the body

You will continue to see hair throughout the course of laser cures. Some of this will be reincreasing. But severe of it will be hair that hasn’t yet been cured. Once your course of cure is complete, you may not see reincrease for several years.

On the body, laser hair removal may supply permanent or very long-lasting outcomes. Over time, any hair that does increase back should be very sparse and fine.

Regrowth on the face

On the face, laser hair removal is not normally long-term but may be long-lasting. Some people study seeing no hair return after 10 years or severe. Others feel reincrease sooner and rely on annual touchup cures to retain unwanted hair at bay.

Side effects

A few different side effects can seem after laser hair removal. Severe side effects are minor and long-term. Anyone feeling lasting side effects should consult their health consultants.

Redness and irritation

Laser hair removal harms the follicles of the targeted hairs. The body responses to this, and severe people feel redness and irritation in the affected areas. However, the skin may tingle or experience tenderness and may even seek to swell slightly.

However, the signs are normally short-lived. The caused area may look similar to skin that has just been enlarged or plucked. Some consultants use a topical anesthetic to decrease how much a person’s skin responds to the process. Irritation should ease after the initial response, normally within a few hours of the cure.


Some people may feel skin crusting in the caused area. However, this is typically a minor problem but can be inconvenient.

Crusting can sometimes guide to scabbing or scarring. By taking care of the treated area after laser removal, like by using a moisturizer, a person may stop, any lasting problems from this treatment.

Changes in skin color

Some people may notice minor color changes to the cured area of skin. However, it may obtain slightly darker or lighter following laser hair removal.

People with lighter skin may be severe likely to feel darker pigmentation changes. People with darker skin tones may be severely prone to lighter pigmentation changes. However, these changes tend to evaporate over time, and the skin returns to the normal phase.

Eye injury

However, the hair removal method may involve the use of powerful lasers. This means there is a greater risk of potentially serious eye injury normally when a practitioner is working on a person’s face.

Both the person collecting the cure and the practitioner should wear safety eye equipment to support stop injury while the method is carried out.

Risk of skin infection

As with other cosmetic hair removal procedures harming hair follicles with a laser can generate infection risk. However, the caused area should be cured as a wound while it heals. People should study any signs of infection with a consultant. Finally, they should not appeal over-the-counter (OTC) antibiotics creams to greater areas of skin if an infection arises.

Rare side effects

However, fewer common side effects following laser hair removal may include the following:-

Burns and blisters

However, there is a risk of burns and blisters if laser hair removal is not finished accurately. However, when a certified person carries out the procedures, burns and blisters are rare.

Laser hair removal operates high-heat lasers. A practitioner may appeal a cooling device to a person’s skin just before the laser is operated. However, this may support stopping the laser from burning the skin.


However, these are typically not a side effect of laser hair removal. If the practitioner builds an error, scarring may happen. This should not be an issue with severe certified practitioners.

Scars may also build if people do not treat the cured area correctly afterward. They should cure the affected skin as if it had been sunburned to ignore further harm. This means retaining it moisturized, protected from light, and examed regularly for symptoms of infection.
