How Does a Laser Hair Removal Session Work?

The Complete Guide: Before / During / After

Dreaming of silky-smooth skin without razors, waxing, or hassle?

Laser hair removal is increasingly popular—but it also raises a lot of questions:

Does it hurt? What should I do before? And after? Is it safe? What happens during the session? How long before I see results?

We explain everything.

Before the Session: Preparation That Ensures Your Safety and Results

It all begins with a preliminary consultation, where the practitioner analyzes your skin, hair type, medical history, and sun exposure habits.

This is an essential step: your safety depends on a personalized and accurate diagnosis.

No worries: in France, practitioners must complete the mandatory foundational laser hair removal training, which lasts several days.

This is crucial: never hesitate to ask for their certifications. A reputable clinic will gladly show them.

Before the session, follow these simple guidelines:

• Shave the area carefully (avoid waxing or tweezing—hair roots must remain intact for the laser to be effective).

• Avoid sun exposure and self-tanning for 4 weeks beforehand.

• On the day of your session: arrive with clean skin, free of lotions, creams, or deodorant.

During the Session: Precision, Comfort, and Controlled Sensations

Once in the treatment room, you’ll be given protective eyewear, mandatory to safeguard your vision.

The practitioner will then adjust the laser settings based on your unique profile:

• Wavelength

• Fluence

• Pulse duration

These settings depend on your skin tone, hair color, and hair type to target the melanin in the hair follicle while preserving the surrounding skin.

Then, the session begins.

Modern devices like the Clinical Skin Laser, designed and manufactured in France, combine powerful energy with built-in cooling systems for a comfortable and precise treatment.

Session duration (approximate):

• Underarms or upper lip: a few minutes

• Bikini area: about 10 minutes

• Half legs: around 20 minutes

Quick and efficient, laser hair removal fits seamlessly into your routine.

After the Session: Normal Reactions and Visible Results

Right after the session, your skin might show:

• Slight redness

• Mild swelling around the follicles

These reactions are normal and temporary—in fact, they’re signs the treatment was effective.

Post-session recommendations:

• Avoid sun exposure for 4 weeks

• Skip intense workouts for 24 hours

• Avoid steam rooms and saunas for 48 hours

• Do not wax or tweeze between sessions—only shaving is allowed

Hair won’t fall out immediately. It’s been destroyed at the root, but will shed naturally within 10 to 20 days, revealing smooth, hair-free skin.

How Many Sessions Are Needed? What Results to Expect

Laser targets only hairs in the anagen (growth) phase.

Since not all hairs are in this phase at the same time, a full treatment plan usually includes 6 to 8 sessions, spaced 6 to 8 weeks apart, depending on the device used.

What to expect:

• After the first session: reduced density, finer regrowth

• After the full treatment: 80–90% of hair permanently removed

• Some may need annual touch-ups, especially those with hormonal imbalances

Most common feedback?

An amazing sense of freedom—no more irritation, ingrown hairs, or upkeep. Just soft, low-maintenance skin.

Pricing: How Much Does Laser Hair Removal Cost?

Prices vary depending on the clinic, the laser used, and the treatment area.

Here are average price ranges:

• Underarms: €40 to €80

• Bikini: €50 to €120

• Half legs: €120 to €180

• Full legs: €180 to €290

Most clinics offer packages or treatment plans, which lower the overall cost.

How to Choose the Right Laser Hair Removal Clinic?

Here are three key factors to guide your decision:

1. The Device Used

Make sure it’s a medical-grade laser (not IPL).

A device like the Clinical Skin Laser, made in France, offers proven performance, safety, and precision.

2. Practitioner Qualifications

The foundational laser training is mandatory—this ensures your safety.

3. The Quality of the Protocol

Look for a clinic that provides:

• A preliminary consultation

• Transparent pricing

• Clear explanations

• Personalized follow-up

These are strong indicators of professional, trustworthy service.
