Both are techniques for hair removal, or more correctly epilation, that fall into the treatment of photo depilation but differ in the technology used to generate light and the properties of light itself.
The laser produces a single wavelength focusing on a particular target (the hair follicle) without being aggressive in the surrounding area. On the other hand, pulsed light generates a wider spectrum of wavelengths, does not concentrate on the hair, and affects the skin’s melanin. Let’s go into detail.

Features and advantages of laser hair removal
As we said, laser hair removal reduces hair growth/elimination through an exact ray of light. The heat generated by light penetrates the hair up to the root, destroying the follicle.
The machines used are specifically set according to the user’s prototype, and the type and color of skin and hair greatly affect the treatment result. For example, the laser is more effective on light skin with dark hair, which contrasts more and is easier to detect.
On the other hand, lighter hairs are hardly distinguishable, and the same problems are found on particularly dark skin. However, from the first session, you start to see weaker and clearer hairs; after three sessions, you can already have excellent results.
Among the advantages of laser hair removal, the most relevant are:
- Painless treatments.
- Stunting of hair growth with permanent reduction.
- It is possible to shave between one treatment and the other, and there is no need to let the hair regrow.
- Effective on the most sensitive areas, such as the face, armpits, and groin.
Laser treatments should be suspended during the summer to avoid damaging the epidermis with spots. If you choose this solution, then schedule the sessions on time.
Features and advantages of pulsed light
There is a wider beam with pulsed light and less precision. Being less powerful than lasers, it is a less effective technique on larger and more stubborn hair and requires more sessions to achieve satisfactory results, but it has the great advantage of being done at home.
The pulsed light epilators for domestic use make it possible to carry out the treatment in the comfort of your home and save on the esthetician. Moreover, they guarantee better and longer-lasting results than traditional methods and razors.
Pulsed light is a particularly versatile technique, which is also used to remove skin imperfections and scars, such as acne, spots, or pigmentation defects.
Among the advantages of pulsed light, the most important are:
- It is not painful.
- Progressive reduction of hair growth and the need for increasingly less frequent treatments.
- It does not require hair regrowth to function.
- Effective on scars, blemishes, and imperfections.
Laser hair removal or pulsed light: Which to choose and when
Both technologies are effective and safe. There is no better one, but everything depends on the type of skin and hair you work with and the area’s size to be depilated. The laser is more powerful, precise, and expensive and is particularly indicated for the most sensitive areas and very contrasted phototypes.
Instead, pulsed light is preferable for large areas and to save money. In any case, it is advisable to evaluate the best choice by contacting competent and prepared personnel on a case-by-case basis.
Are there any contraindications?
In principle, no. Laser hair removal and pulsed light are tested and safe procedures, but they are not suitable for everyone, and, above all, they must be done correctly.
In the case of skin particularly sensitive to light or visible wounds and bruises, it is better to avoid or consult the doctor. The same applies to pregnant women or people being treated with drugs with photosensitizing properties.
In conclusion, before choosing to use laser hair removal or pulsed light, it is always advisable to consult a doctor, a dermatologist, or at least a specialized beauty center to be directed in the right direction.
