Advantages and Disadvantages of Laser Hair Removal

The advantages of laser hair removal are undoubted, since it is a fast and safe method, that keeps the skin free of hair for a long time (in many cases of definitive form), and allows to depilate ample zones.

In addition, it also has medical applications, and patients with pathologies such as pseudofolliculitis orhirsutism , or those who needed to depilate skin grafts, have benefited from this technique.

Disadvantages of Laser Hair Removal

However, do not lose sight of the fact that laser hair removal has some drawbacks:


When you apply the laser, it is normal for you to feel a burning sensation or puncture which, during the first two or three sessions (when the hair is still abundant), is usually quite annoying, especially if you are shaving an area where the skin is Especially sensitive, like English. Cooling systems that incorporate some equipment greatly reduce pain and, from the fourth session, the slight punctures are perfectly tolerable. In any case, stripping the hair with wax is also not pleasant, and laser hair removal has the advantage that hair growth is delayed a lot and sessions are increasingly spaced more.

You can consult the doctor to use an anesthetic cream if the area to be treated is very sensitive or has a high follicular density, but it is quite cumbersome to use because you should apply it about an hour before the session and cover the area with a plastic . As with other cosmetic treatments, laser hair removal continues to evolve, and for a few years now a new laser, the Vectus ™, has been available which, in addition to being more effective in removing more hair per session – Makes it ideal for large areas such as the legs – is virtually painless because it applies the energy in a homogeneous way avoiding the occurrence of annoying heat spikes.

Rebel zones

It is important to note, however, that there are areas where the hair tends to reappear with insistence, as with the facial area . We have already explained that this is because during the session the active hairs are removed, but the laser does not affect the resting hair follicles, which can be activated over time. Even so, getting rid of excess facial hair by laser is still convenient, since the new hairs would go away equally with any other depilatory method, or even if none were used.

Androgens or related hormones also stimulate hair growth, both in males as they mature (thorax, abdomen, back, lumbar region …), and in certain women with hormonal disorders (such as hyperandrongenism), and in those cases, Patients will require refresher sessions over time to remove new hairs.

Fine hair and hairs

The laser does not remove gray hair or thin, clear hair. Fine hair (the most common on women’s faces), does not absorb well the light emitted by the laser, even if it is somewhat dark, and for this reason the doctor must assess the characteristics of the patient’s skin to see if it is It is possible to use the laser to depilate this type of hair in its specific case.

Dark skin

Although there are laser devices that can be used with relative safety on dark skins, the patient should be pre-evaluated by a physician. In addition, the procedure may be less effective and more troublesome.

In pregnancy

During pregnancy it is contraindicated to perform laser hair removal in areas close to the abdominal and pelvic region, to avoid any possible damage to the placenta or fetus. In the case of areas away from the fetus, the pregnant woman should consult her doctor beforehand or stop treatment until after the birth .


If you are taking any type of medication you should advise the doctor to check if the drugs produce photosensitivity , as is the case with isotretinoin. You should also advise if you are diagnosed with a new pathology or prescribed a new medication before undergoing a new session of laser hair removal in case any interaction could occur.

Although the risk is minimal if the depilation is performed by a qualified professional with the prior evaluation of a doctor, it may happen that the melanin of the patient’s skin absorbs part of the light energy destined for the hair follicle and, as a consequence, the skin Overheating and significant irritation or even a burn.
