Striae distensae (stretch marks)
Another very common blemish that can be successfully treated with the laser therapy are the striae distensae, also known as stretch marks. These blemishes are characterized by linear bands of atrophic or wrinkled skin that result from excessive dermal stretching, such as after rapid weight loss/gain, pubertal growth or pregnancy. In their early stages, they are present as a dermal inflammation with dilated capillaries, which results in an erythematous appearance. In the terminal phase, striae appear hypopigmented and fibrotic owing to the linear deposition of dermal bundles and the thinning of the overlying epidermis.
The result of laser scar treatment is a flattening of the edges of the scar, a visible improvement in the skin texture and in the color of the scar, which becomes lighter.
What types of scars can be treated?
Laser scar removal can work on many skin types, including very light and very dark skin. The best results are observed on atrophic and acne scars, which are normally relatively flat. The procedure can also be used successfully for the treatment of striae, resulting in an improvement in the appearance of the scar (no removal). The treatment of hypertrophic and keloid scars (that are normally pink, raised, firm and erythematous) is not recommended.
Is the treatment painful?
Most people feel minimal discomfort during laser scar treatment. The treatment is normally well-tolerated, however a local anesthetic may be used for particularly sensitive areas.
How many sessions are necessary?
According to the size and location of the scar, several sessions may be needed. A course of three to seven treatments can, in most cases, provide good aesthetic results.
How long is the recovery time?
The recovery time is usually very short. Most people resume regular activities immediately following the treatment session. During the first 48 hours, there may be a sensation of heat or burning similar to sunstroke – discomfort that will vanish thanks to the use of creams indicated by the physician. For 10-15 days afterwards, the skin will have a smooth appearance with a reddish color that can easily be covered with light makeup and without affecting your daily activities or social life.
Are there any undesirable side effects?
Typical side effects include temporary redness and swelling, which should last only a few days. There is a low risk of prolonged itching, redness, and blistering. There may be some unsightly dark marks, which always disappear within a few weeks, either on their own or by following your physician’s instructions.
