What are these treatments: laser or pulsed light?

Laser hair removal and intense pulsed light (IPL) are two modern photoepilation techniques that use light to permanently remove hair. However, their technology, accuracy, and efficiency differ substantially.

Medical laser hair removal consists of directing a monochromatic beam (of a single wavelength, very targeted) at the melanin of the hair. Light energy is transformed into heat only where there is pigment (melanin), destroying the hair bulb without damaging the surrounding skin. The lasers used at the Biolaser Center, for example Alexandrite or Nd:YAG, are designed for optimal safety and power and can act on several skin types.

Pulsed light hair removal, or IPL (Intense Pulsed Light), uses a lamp that emits a polychromatic light (several wavelengths), which is less targeted. It does not only focus on the melanin of the hair and the energy delivered is less precise. IPL is often used in beauty salons or at home, while medical laser hair removal must be performed by a health professional equipped with approved medical machines.

Remember that the ability of each technology to target the hair and the safety of the bulb destruction are determining factors in the success of a long-term hair removal treatment, especially on specific skin and delicate areas.

For which indications should laser hair removal or pulsed light be chosen?

Both techniques target long-lasting hair removal, but the field of action of each differs and their effectiveness is not the same.

Indications for medical laser hair removal

Medical laser hair removal is indicated for:

• Any unwanted hair: legs, armpits, bikini line, back, torso, face, arms, hands, feet, areolas, etc.
• Men and women, adults but also adolescents (after medical advice)
• Light to dark or dark skin (phototypes I to VI), thanks to the diversity of medical lasers (Alexandrite, Nd:YAG)
• Dark, thick or semi-fine hair
• Cases of recurrent ingrown hairs, folliculitis or female hirsutism

Indications for Pulsed Light (IPL)

Pulsed Light (IPL) addresses the same areas of the body, but has significant limitations:

• Works especially on very light and dark skin
• Ineffective on light, red or very fine hair; Not recommended on dark to dark skin (increases the risk of burns, pigmentation disorders or ineffectiveness)
• Contraindicated on high phototypes or tanned skin
• Never pathological treatment, nor prior medical analysis

As a result, the medical laser has a real advance in terms of the diversity of patients cared for and for tailor-made results adapted to each skin. For a global overview of all the indications for laser hair removal, see our dedicated page.

Can all areas be treated with these techniques?

Yes, the entire body and face (upper lip, chin, sideburns, cheeks) can theoretically be treated. Nevertheless, safety and maximum effectiveness are observed in medical settings for sensitive areas, including the female face, bikini line, armpits, areolas or for darker skin tones.

How does a session work: laser or IPL?

Procedure in a doctor’s office (laser)

At the Biolaser Center in Saint-Louis, near Basel, the medical laser hair removal protocol follows a safe path:

• Initial consultation: medical diagnosis, skin and hair study, information, written quote and informed consent.
• Preparation: the area is shaved (razor) the day before or the morning of the appointment, no cream or perfume is applied, no recent sun exposure or self-tanner.
• Session: use of the most suitable laser according to your phototype (Alexandrite, Nd:YAG). Each bulb is targeted, a cooling device protects the skin and improves comfort. Duration: from a few minutes (face) to 60 minutes (full legs).
• Eye protection: filtering glasses are mandatory for everyone (patient and practitioner) throughout the procedure.
• After the session: soothing cream and personalized recommendations.

Conducted in an institute or at home (IPL)

With pulsed light, the process is often standardized: no medical diagnosis, less personalized settings, similar gestures (flash / zone-to-zone movement) but without fine adaptation to the specificities of your skin or control by the supervisory staff. If you live with IPL devices for the general public, the risk of ineffectiveness or adverse effects is accentuated.

Thus, the follow-up, effectiveness and safety are incomparable between protocoled medical laser hair removal and pulsed light hair removal practiced outside the medical environment.

For more details on the procedure and medical support, see our explanatory page on laser hair removal.

Number of sessions needed for optimal results

The hairs grow in cycles (anagen, catagen, telogen phase), and only the active hair units (anagen phase) react to the session. The number of sessions varies according to the individual, the area, the hair density, the technology chosen.

Laser hair removal: speed and durability of the result

With the medical laser, it is necessary to consider an average of 6 to 8 sessions spaced out over several months (4 to 8 weeks apart). This protocol makes it possible to permanently eliminate up to 90 to 95% of hair. Annual maintenance is sometimes proposed in the event of residual regrowth (new bulbs or subsequent hormonal changes).

Pulsed light: high number of essential sessions

With pulsed light (IPL), it usually takes 8 to 15 sessions or more, because the energy less systematically reaches each bulb. Deep hair destruction is not guaranteed by intensity or targeting. Maintenance (frequent servicing) is often unavoidable to maintain a minimum of results.

So notice a marked difference between laser hair removal and pulsed light : the number of sessions is less and the durability is much better with the medical laser.

Expected results after laser hair removal or pulsed light

The major challenge in choosing laser hair removal vs. pulsed light is the durability and intensity of the results, as well as the aesthetic safety in the long term.

What the medical laser allows

The well-conducted medical laser results in a disappearance of 90 to 95% of the hair on the treated area, for most phototypes and hairs, except for white hair. The residual hairs become few, very fine and lighter. The effect observed is usually definitive, except for subsequent hormonal stimulation or underlying pathology.

What IPL allows

IPL leads to a temporary reduction (usually 50 to 70% of density), but regrowth partially resumes as soon as treatment is stopped or a few months after maintenance. The hairs often grow back finer but in varying numbers, without any lasting guarantee.

Benefits of medical laser on sensitive areas

The medical laser also ensures better precision on the face, bikini line, areolas, difficult areas or dark skin, without stimulating the paradoxical regrowth possible with IPL lamps (especially for the unsuitable female face).

Possible side effects and safety

Both laser hair removal and IPL are considered safe techniques when performed under the right conditions. Nevertheless, some mild and transient side effects may occur, which should be monitored:

• Redness or erythema on the treated area (a few hours)
• Feeling of warmth or slight tingling (classic, well tolerated thanks to active cooling)
• Localized and moderate edema
• Very rare scabs, pigmentary disorders (transient hyper or hypo-pigmentation), mainly in case of use of IPL on dark skin or unsuitable settings
• Very rarely, secondary infections in the event of scratching or unsuitable exposures

The safety of the medical laser is based on the personalized adjustments to the patient’s phototype and hair, compliance with contraindications, and follow-up by a competent medical team. Serious side effects are exceptional; they are more common with IPL machines from institutes or at home.

It is essential to report any unusual reactions to your practitioner in order to adapt the follow-up. Contraindications (pregnancy, undiagnosed lesions, taking certain photosensitizing medications, etc.) are systematically checked before each start of treatment in the office.

Advice after each laser or IPL hair removal session

To optimize skin recovery and protect your results, systematically apply after your session:

• No sun exposure (or UV cabin) for at least 2 to 3 weeks after each session: apply an SPF 50 sunscreen if accidental exposure
• Soothing or emollient cream in case of redness or discomfort (such as Biafine, Cicalfate, etc.)
• No scratching of any scabs/redness, let the skin regenerate naturally
• No swimming pool, hammam or sauna (48 hours minimum)
• No tanners, perfumes, chemical bleaches on the treated area before full recovery
• Follow-up appointment if you experience an unusual side effect (pain, blister, etc.)

These instructions are systematically given after each session at the Biolaser Centre. They are valid for all laser hair removal vs. pulsed light, the recovery remaining similar but the risk of adverse effects is lower with the supervised medical laser.

Expert opinion – Dr. Michaël Thanacody, aesthetic doctor and laser therapist at the Biolaser Center — Saint-Louis

“When comparing laser hair removal vs. pulsed light, the main criterion for the doctor must be safety, and then effectiveness. The medical laser has the immense advantage of targeting the hair root with unparalleled precision, while allowing the parameters to be adjusted to each patient, for each area and each phototype, including dark skin. IPL remains a more superficial and more random technique, which I do not recommend using outside of a medical environment to avoid unnecessary risks. In the long term, choosing laser hair removal means opting for a long-lasting, safe and qualitative result under medical supervision.”

Conclusion: laser hair removal vs pulsed light, which choice should you choose?

To sum up, the comparison of laser hair removal vs pulsed light clearly shows the superiority of the medical laser in terms of safety, effectiveness, speed of the protocol and durability of the result, regardless of the area to be treated or the color of the skin. The medical laser, performed in a specialized practice such as the Biolaser Center in Saint-Louis near Basel, is the solution of choice to guarantee safe and permanent hair removal, at the cost of personalized follow-up by experts in aesthetic medicine.

Pulsed light (IPL) remains reserved for special cases, often for a temporary alternative on very fair skin. For delicate areas or if you want to entrust your permanent hair removal project to a professional who can precisely adjust each parameter to your situation, the medical laser brings a clear advantage.
