Subdermal Laser Treatment: How It Is Done, Who It Suits and Its Limits

Subdermal laser treatment is a procedure in which a very thin laser fibre is placed under the skin through a small entry point; it does not require surgery but involves entering beneath the skin (minimally invasive). The aim is to tighten the tissue under the skin and reduce a limited amount of fat tissue through the heat produced by the laser energy. This article explains when subdermal laser treatment is considered, how it is done, its limits and its risks.

When Is It Considered?

• Mild to moderate laxity in the lower face and along the jawline
• Limited fat accumulation under the chin
• Mild skin laxity on the neck

In some cases it may also be considered for body areas such as the upper arms or the inner knees. This treatment is not enough for marked sagging and excess skin; in these cases surgical options such as a face lift are more suitable. The doctor decides which method is suitable after an examination.

How Is It Done?

The doctor first assesses the treatment area and the person's expectations. The area is cleaned and numbed; the treatment is usually performed under local anaesthesia. The laser fibre is placed under the skin through an entry point opened with a very fine needle and is moved across the planned area while laser energy is delivered. The energy level and treatment area are adjusted by the doctor for each person. If needed, the procedure may be repeated after some time.

Who Should Not Have It?

The treatment is not performed during pregnancy and breastfeeding or if there is an active infection or an open wound in the treatment area. In conditions such as a bleeding or clotting disorder, a tendency to scarring, fillers or permanent implants in the treatment area, uncontrolled chronic illnesses and the use of medicines that cause sensitivity to light, a doctor's assessment is needed first. Blood thinners and other regularly used medicines should not be stopped without consulting a doctor, and the doctor who will perform the treatment should be informed of them in advance.

After the Treatment and Expectations

• Swelling, bruising, tenderness and a mild feeling of tightness are expected in the first days.
• The care recommended by the doctor should be followed; the area should not be pressed or massaged.
• The period recommended by the doctor should be observed before saunas, Turkish baths, intense exercise and direct sun exposure.

The tightening effect appears slowly over weeks and months and varies from person to person. The result is not permanent; the ageing process continues.

Possible Risks

Swelling, bruising and tenderness are common and usually temporary. Less commonly, burns, firmness or irregularity of the skin, discolouration, infection and temporary numbness may occur; very rarely, temporary asymmetry due to involvement of branches of the facial nerve has been reported. If increasing pain, redness, blistering, discharge, fever or a change in facial movements is noticed, a doctor should be consulted immediately.
