Scars and lasers: There are different types of acne scars. Scars with disorders of the relief (intaglio) require the use of lasers that cause remodeling a lifting effect by stimulating growth of collagen in the skin.
The dominant red scars can be alleviated by vascular lasers. Pigmented scars will benefit from laser treatments pigment or tattoo removal.
1450 nm Laser Treatment - 4 sessions spaced one month each.
The therapeutic strategy of the laser will be multiple:
Faced with a pigmented scar, it will seek to break up the pigment melanin to allow it to be removed by cleaning the cells of the body. Lasers are commonly used Q-switched lasers (laser tattoo removal and pigmentation) and the Alexandrite lasers (laser hair removal and pigmentation). There are generally 1-2 session to treat pigmented areas.
Q-switched Laser Traditionally Used - for tattoo removal and pigmented spots.
Faced with a red scar of vascular component, the laser physician will seek to reach the small vessels in the sclerotic. This sclerosis may take several weeks after the laser action. The facilities are traditionally used lasers are the KTP laser or pulsed dye lasers.
KTP Laser Diode Used in Pigment - or pigment vasculature to treat acne scars vascularized
Faced with a depressed scars or atrophic or ice pick, the doctor will use laser properties of laser reshaping of deep penetration of Nd: YAG or diode-YAG 1450 nm. It should not be forgotten that there is also sometimes listed Autes techniques and more efficient in some cases.
1450 nm Laser Diode - used to reduce acne, to reduce acne scars, to rejuvenate the face and reduce wrinkles
Faced with hypertrophic or keloid scars, the use of the laser must be very careful so as not to aggravate the injury. Other therapies are generally preferable.
What Lasers for What Type of Scars?
The simple forms of acne can usually benefit from local treatment based creams, lotions or ointments.
Depressed scars - if some crater acne scars are more a matter of minor surgery with survey techniques or suture excision, the light to medium lasers are available for remodeling (1450 nm). The results are generally good with an attenuation of acne lesions. It takes usually 3 to 4 sessions to get optimum results in terms of remodeling.
Ice pick scars acne in "ice pick" if they are also treatable by surgical suture, it remains a disease of choice for laser reshaping. Machines like the Candela 1450 nm, or Aramis Quantel. The 1450 nm laser type require between 3-4 sessions. The lifting effect continues to occur several months after the last session.
Pigmented scars of acne: they are easily treated with pigment lasers. Among the lasers to treat the pigments, there are the laser hair removal like Alexandrite, KTP vascular lasers, laser tattoo removal Q-switched. Each has its own indications depending on the damage to be considered. There are usually 1 to 3 sessions of laser scars.
Red scars acne hypervascular: This type of scarring can be treated with vascular lasers or KTP laser type pulsed dye laser. They destroy by multiple small superficial vessels. It usually takes 1-3 sessions.
Progress of a Laser Sessions for Scars
The laser sessions to fight against the scars are conducted in medical office or clinic. They are rarely performed in centers commercial lasers, usually focuses exclusively on waxing.
An initial medical examination before any treatment classic: Before treatment, the patient should have a consultation with a medical examination and clinical examination. The examination by the laser physician must seek to trace the history of the patient's acne, treatments already undertaken and the results obtained. It must also ensure that the skin does not cons-indication to the realization of laser treatment. (Non-healing disorders, absence of bleeding disorders, lack of sensitivity to hot or cold, lack of certain medications, lack of current pregnancy ...)
Conducting a thorough clinical examination to type scars laser and evaluate the strategy to use:
Sometimes the laser physician performs an act required by the dermatologist or general practitioner, it therefore has a monitoring and an accurate diagnosis from his colleague. This does not, of course driving a skin examination to classify acne scars, identify and choose the laser to be used. Dermatologists and lasers work in cooperation and usually take lots of pictures. This allows to follow the evolution of skin lesions which eventually do more than remember when they disappeared.
Conducting a skin test a small area before starting any treatment.
Skin, and especially of the face, is a valuable asset. Of care in aesthetic lasers, the greatest caution because the goal is to obtain an improvement of acne scars. In almost all cases and cabinets laser practitioners make a laser test an inconspicuous area of the face (usually behind the ear) and allow themselves a fortnight to assess the reaction of the skin. The test is to find the right setting of the machine. The analysis of the reaction of the skin, two weeks later, ensures that the treatment is well tolerated. This period of 15 days is also a time when the patient can think about the calm before making a decision.
