Stretch marks are extremely common and can appear at different stages of life. Pregnancy, rapid growth, significant weight fluctuations, or hormonal changes can cause them to develop on various areas of the body, particularly the breasts, abdomen, thighs, hips, and buttocks.
Although completely normal, these small lines on the skin can become a cosmetic concern. When they have been present for several years, creams and topical treatments generally offer limited results. The fractional CO₂ laser can therefore be an interesting option for improving their texture and appearance.
Why Do Stretch Marks Develop?
Stretch marks, also known as striae distensae, occur when the skin is subjected to significant or relatively rapid stretching. The dermis, located beneath the epidermis, undergoes changes to its collagen and elastin fibers.
They may initially appear as red, pink, or purplish lines. Over time, they generally become lighter and take on a whitish, slightly indented appearance.
Stretch marks can develop:
- after pregnancy, particularly on the abdomen and breasts;
- during adolescence and periods of rapid growth;
- following significant weight gain or weight loss;
- during certain rapid changes in body shape;
- on the thighs, hips, buttocks, or abdomen.
It is important to understand that a stretch mark is a true structural change in the skin. There is therefore no treatment capable of making stretch marks disappear completely. The goal of aesthetic treatment is instead to reduce their appearance and improve the overall quality of the skin.
How Does CO₂ Fractional Laser Treatment Work on Stretch Marks?
The fractional CO₂ laser uses light energy to create microscopic treatment zones in the skin, leaving areas of untreated skin between them. This controlled stimulation triggers the skin’s natural healing process and promotes the production of new collagen.
As the skin heals, it may become more even, firmer, and smoother.
When treating stretch marks, the goal is therefore not simply to “erase” the visible lines. Instead, the laser works on the quality of the skin tissue to achieve a gradual improvement in the texture and appearance of stretch marks.
Clinical studies and reviews of the medical literature have also shown that fractional CO₂ laser treatment can improve the appearance of stretch marks, particularly when used as part of a protocol tailored to the type of stretch marks and the patient’s skin type.
Can Stretch Marks on the Breasts Be Treated?
Yes. The breasts are a common area affected by stretch marks, particularly following pregnancy or significant changes in breast volume.
However, treatment must be adapted to the sensitivity of this area and the condition of the skin. A medical assessment can help determine whether CO₂ Fractional laser treatment is the most appropriate option and which treatment parameters should be used.
The goal will generally be to reduce the contrast between the stretch marks and the surrounding skin while gradually improving their texture.
What About Stretch Marks on the Abdomen?
The abdomen is one of the areas where stretch marks are particularly common, especially following pregnancy or significant weight changes.
When stretch marks are older, white, and slightly atrophic, fractional CO₂ laser treatment may be used to stimulate skin renewal and collagen production.
However, it is important to maintain realistic expectations: significant improvement may be possible, but stretch marks will not disappear completely.
Can the Thighs Also Be Treated?
Absolutely. The thighs, as well as the hips and buttocks, can develop stretch marks associated with growth, weight fluctuations, or changes in body shape.
As with other areas of the body, the treatment protocol should be customized according to the age, depth, and extent of the stretch marks, as well as the patient’s skin type.
Red or White Stretch Marks: Does It Matter?
Yes.
Recent stretch marks are generally red or purplish. At this stage, they are still in an inflammatory phase, and certain treatments may be particularly beneficial.
Over time, they become white and more atrophic. They are then considered older scar-like lesions. Treatment remains possible, but the primary goal will be to improve their texture and appearance rather than eliminate them.
The choice of technology and treatment parameters must therefore take into account the stage of development of the stretch marks.
How Many Treatments Are Needed?
The number of sessions varies from person to person. It depends on factors such as the area being treated, the depth and age of the stretch marks, and how the skin responds to treatment.
Fractional CO₂ laser treatment may require several sessions, spaced sufficiently apart to allow the skin to recover and the collagen remodeling process to continue. Two to three treatments may be sufficient in some cases.
Results are therefore not necessarily immediate. Improvement develops gradually over the weeks and months following treatment.
A Technology That Requires Medical Assessment
CO₂ laser treatment is not the same for every skin type. Selecting the appropriate treatment parameters is particularly important to achieve improvement while minimizing the risk of complications, including changes in pigmentation.
A consultation with Dr. Mario F. Bernier allows the skin, characteristics of the stretch marks, and treatment area to be assessed in order to determine whether fractional CO₂ laser treatment is an appropriate option.
With this technology, only Fitzpatrick skin types I, II, and III can be treated. For skin types IV, V, and VI, other treatment options are available.
At the Dr. Mario F. Bernier Aesthetic Medicine Clinic in Laval, fractional CO₂ laser technology is used to improve various skin imperfections. Depending on their characteristics, treatment can also be adapted to scars and stretch marks.
Improvement, Not a Promise of Complete Removal
Stretch marks are part of the skin’s history. Pregnancy, growth, or significant changes to the body can leave marks that remain visible for years.
The goal of CO₂ fractional laser treatment is therefore to make stretch marks less noticeable and improve the overall quality of the skin, rather than promise their complete removal.
A personalized assessment remains the best way to determine what results can reasonably be expected.
