Laser: the permanent medical hair removal
Laser hair removal was introduced two decades ago and has been evolving year after year. In NEODERMA CENTRO MÉDICO we have the most advanced technology in the European and American market, with up-to-date and effective medical hair removal equipment. This, combined with the fact that the treatments are performed by specialized medical professionals, accredits us as one of the best centres in this sector.
We have the Alexandrite, Diode and Neodymium Lasers as reference:
ELITE MPX OF CYNOSURE
ELITE OF CYNOSURE
LIGTH SHEER OF LUMENIS
NEODIMIO OF CYNOSURE
All of them approved by the FDA and the CE.
ALL TREATMENTS ARE PERFORMED BY SPECIALIZED MEDICAL PROFESSIONAL WITH GREAT EXPERIENCE.
In NEODERMA CENTRO MÉDICO our priority is your safety, your health and the results.
Laser hair removal is recommended for the following cases:
Hypertrichosis: excessive growth of terminal hair without distribution of male type.
Hirsutism: presence of terminal hair with male pattern in women.
Recurrent pilonidal cyst.
Family history of pilonidal cyst in patients with hypertrichosis.
It is absolutely contraindicated in the following cases:
Tanned skin (sun exposure in the last month).
Photosensitivity by disease or drugs (abnormal skin reaction resulting from exposure to the sun or drugs).
Treatment with 13-cis retinoic acid (acne treatment that should be over 7 months before the laser hair removal treatment).
Pregnancy and lactation.
Ocular area (unless adequate protection).
Areas with neoplasia (process or malignant or benign tumour).
And limited in:
High risk of keloid scar.
Pigmented injuries that you do not want to treat.
Decompensated diabetic patients (risk of ulcers by burns).
Patients with recurrent herpes simplex in treatment area (except preventive treatment).
Areas recently depilated by avulsion (wax, tweezers, electric devices, etc.).
How does laser hair removal work?
Lasers achieve permanent hair removal by being designed to heat the hair follicle at temperatures close to 100ºC –and thereby inducing hair removal– without causing damage to the skin. This is possible because the laser can emit a specific light that is selectively absorbed by the melanin –our target– and yet the rest of the skin, which formed mainly by water, absorbs it badly. This phenomenon is known as selective photothermolysis and allows to design the laser playing with parameters such as wavelength, pulse duration and emitted energy to achieve the destruction of the follicle while preserving the skin.
Laser hair removal is the best method to remove the excess of unwanted hair. It is a painless, simple, safe, effective and definitive treatment in most cases.
It is suitable for both sexes and at any age. It can be used in any part of the body: face, neck, chest, armpits, arms, groins, legs, abdomen, back, buttocks, hands and feet.
It does not damage the skin and it does not damage its sebaceous or sweat glands.
It is not carcinogenic since the light it emits is in the range of visible and infrared light.
It is not teratogenic. It does not emit ionizing radiation: its thermal effect is limited to the skin because it reaches 4 mm deep.
How many laser hair removal sessions are needed?
To make depilation permanent we must destroy the pluripotential cells responsible for regenerating the follicle. The number of required sessions depends on the individual response of each person, although in general it usually takes between 3 and 6 sessions to achieve a 90% total hair removal. Areas such as groins, armpits, areolas respond better to treatment in 4 sessions. It is necessary to leave a period of 1 to 3 months between sessions depending on the area as it is the time after the laser treatment that most of the hair follicles that have not been treated need to enter a new growth cycle.
Laser Hair Removal Effectiveness
The effectiveness of the laser will depend on several factors:
– Phases of the follicular cycle (depends on each person)
– Hair thickness
– Hair colour
– Depth of hair
– Follicular density (number of hairs per cm2)
– Skin colour or cutaneous phototype
– Treated body area
– Hormonal status
– Number of sessions held
Can all skin and hair colour be addressed with a laser hair removal treatment?
In NEODERMA CENTRO MÉDICO we have the technology necessary to treat all types of skin. However, when targeting melanin, the result is very poor in white hairs where melanin does not exist or is in very low concentration.
Is laser hair removal painful?
Patients feel something like a small puncture but it is completely bearable. Just after treatment, it is normal to develop a slight redness that can last for a few hours. It is important to note that the laser is non-ionizing and therefore it does not have the dangers X-rays have.
The most frequent complication is the hyperpigmentation of the treated area, especially in patients who have been exposed to tanning after treatment, so sunbathing in the areas to be treated should be avoided at least 7 days prior the laser session.
Why have we chosen to work with the Alexandrite MPX and Diode LightSheer laser?
Nowadays there is a large variety of laser equipment and pulsed light systems on the market that are used for permanent hair removal. They do not all have the same effectiveness, though.
In NEODERMA CENTRO MÉDICO we work with the Diode LightSheer laser –developed in the Wellman laboratory of Harvard University (Massachusetts) and approved by the American FDA (Food and Drug Administration) and CE– as well as the Alexandrite ELITE MPX laser by CYNOSURE –also approved by the FDA and CE– given that they have proven to be the best medical equipment for permanent hair removal and are considered world leaders in medical hair removal.
Pre-treatment indications for proper medical hair removal
The area to be treated should not be depilated with any root hair removal system for at least the last 15 days prior to the treatment.
The area should be shaved 1 or 2 days before or be shaved at the medical centre.
Do not use products that can irritate the skin for at least 3 days before treatment like creams with glycolic acid, vitamin A or Retinol, astringent products, etc.
The number of sessions to be performed on the specific area is based on different factors such as:
– Race, age, sex, hormonal problems, etc.
– The growth phase in which the hair is at the time of starting the treatment.
– The creep (energy) tolerated by the skin.
– The normal thing is to receive 3 to 6 sessions per body area.
