Laser hair removal is an increasingly popular method to get rid of unwanted hair permanently. A first consultation is necessary to assess the patient’s skin and hair, as well as to discuss expectations and medical history. But how does it really work? What technology is used? What possible results can be obtained and what are the risks associated with such a treatment method? Here’s what you need to know before diving into this adventure!

The Technology of Laser Hair Removal

Laser hair removal relies on the use of concentrated light beams to eliminate unwanted hair permanently. This technique exploits a principle called “selective photothermolysis.” The laser energy targets the melanin by heating the hair follicle until it is destroyed without damaging the surrounding tissues.

Indeed, different types of lasers are used. Among the most common are:

• The alexandrite laser: ideal for light skin and dark hair;
• The ND:YAG laser: suitable for darker skin tones;
• The diode laser: versatile and effective on a wide range of skin types.

Thanks to its different types of lasers and personalized approach, the centremedicalcroixrousse.fr offers you a quality experience and satisfactory results.

Results Obtained

The results of laser hair removal vary depending on several factors. But objectively, this advanced hair removal method offers considerable advantages over traditional ones.

Significant Hair Reduction

The main advantage of laser hair removal is its ability to significantly reduce hair growth in the treated areas. The laser targets melanin, the pigment that gives hair its color, and destroys it by heating. By targeting hair follicles in the anagen phase, the active growth phase, it attacks the hair when it is most vulnerable.

The number of sessions needed to achieve optimal results varies depending on several factors, such as:

• Skin type;
• Hair color and thickness;
• Area to be treated.

Since not all hair is in the anagen phase simultaneously, multiple sessions are needed to effectively treat the entire area. However, on average, 6 to 10 sessions are sufficient to eliminate 80 to 90% of hair on most body areas.

Smoother and Softer Skin

By reducing ingrown hairs and irritations related to shaving or traditional hair removal, the skin becomes smoother and more uniform. Ingrown hairs occur when hairs, after being cut or pulled, grow back under the skin, causing inflammation and infections. By eliminating the root of the problem, laser hair removal prevents these discomforts, offering smoother and more homogeneous skin.

Moreover, since the laser targets only the hair without damaging the surrounding skin, there is less risk of skin irritations. Integrated cooling devices and dynamic scanning techniques also help minimize sensations of heat or tingling.

Durability of Results

Although laser hair removal does not guarantee permanent hair elimination, the results are long-lasting. Unlike temporary methods like shaving, depilatory cream, or waxing, laser hair removal offers a long-term solution.

Damaged follicles no longer produce hair or produce less, much finer and sparser. This allows for smooth skin for long periods without the need for regular treatments. Although maintenance sessions may be necessary occasionally, they are usually spaced out over several months or even years. But is there not a risk involved?

Contraindications

Laser hair removal is generally safe and effective. However, certain medical conditions, specific skin conditions, and even particular behaviors can make the treatment inappropriate or risky.

Tanned or Recently Sun-Exposed Skin

When the skin is tanned, either from prolonged sun exposure or artificial tanning sessions, it contains a higher amount of melanin. The principle of laser hair removal is based on the absorption of light by the melanin in the hair. Tanned skin, rich in melanin, can also absorb this light, leading to risks of burns, hyperpigmentation, or hypopigmentation.

Therefore, it is recommended to avoid sun exposure for at least six weeks before the laser session. If you have just returned from vacation or recently tanned, it would be wise to postpone your treatment.

Presence of Tattoos in the Treated Area

The laser technology targets the melanin in the hair to destroy it. However, tattoo ink also contains pigments that can absorb the laser light, which can cause significant damage to the tattooed skin.

Risks include burns, blisters, scars, and even discoloration or partial destruction of the tattoo. These complications can not only be painful but also aesthetically damaging. The same applies to skin prone to depigmentation or skin infections.

Active Skin Infections

Laser hair removal should never be performed on skin with active infections. The laser can cause additional inflammation, spreading the infection and delaying the healing process. Moreover, the treatment can be painful and lead to scarring or more serious complications.

In any case, consult a dermatologist for an accurate diagnosis and appropriate treatment. Once the infection is resolved, a waiting period may be necessary before safely proceeding with your laser treatment!
