Stretch marks on the skin can be aesthetically bothersome and may affect self-confidence-especially for women. Stretch marks (striae) can develop for many different reasons, and they are one of the most common body skin concerns seen in aesthetic dermatology.
Stretch marks form when the dermis (the deeper layer of the skin) is overstretched. One of the most frequent triggers is rapid weight gain and weight loss, which causes the skin to thin and weaken over time. As the skin stretches, microscopic tears may appear, resulting in the classic "torn" or "lined" look associated with striae.
From the outside, stretch marks are usually visible as linear changes in texture and color. It is often easy to distinguish the affected area from surrounding healthy skin. Newly formed stretch marks typically look darker than the natural skin tone, sometimes appearing red-purple. Over time, these marks usually fade and become lighter, but they may remain noticeable.
Although stretch marks do not usually damage the overall integrity of the skin, they can be cosmetically disturbing, leading many individuals to seek professional solutions such as laser stretch mark treatment, radiofrequency, or regenerative techniques.
Stretch marks are also extremely common during pregnancy, as the abdomen and waist expand quickly. In this period, stretch marks may develop on the abdomen, hips, thighs, calves, and lower back, and they are often referred to as "pregnancy stretch marks."
For patients looking for stretch mark treatment in Turkey, Tekirdağ offers a strong advantage thanks to its location near Istanbul, making it easier for patients traveling for aesthetic care to access treatment options without the intensity of the city center.
What Causes Stretch Marks?
Before explaining why stretch marks occur, it is useful to understand the structure of the skin. From top to bottom, the skin consists of:
- Epidermis
- Dermis
- Hypodermis
The dermis layer contains elastin and collagen fibers, which are essential for healthy skin appearance and elasticity. When these fibers weaken or break, visible structural changes can occur. Two major factors stand out as the most common reasons for stretch mark formation:
- Pregnancy
- Rapid weight change
During pregnancy, the skin experiences significant tension due to fast weight gain and expansion, which can lead to collagen and elastin fiber disruption. Stretch marks commonly appear during the third trimester (the last 3 months) and are often most visible in the abdominal and waist areas. In addition, swelling (edema) can contribute to stretch marks on the breasts and the inner parts of the legs.
Stretch marks may also occur during adolescence, especially when the body changes quickly. As muscle mass develops, stretch marks can appear in areas where muscle growth is most prominent. This is also common in individuals who do bodybuilding or intense muscle-building workouts.
In addition, hormonal changes can contribute to the development of striae. Certain medications may also lead to stretch marks, particularly systemic corticosteroids, which can negatively impact collagen and elastin fibers. Similar stretch mark patterns can appear in diseases where cortisol levels are altered.
Some infections and systemic conditions may also affect the dermis and contribute to stretch marks. In rare cases, stretch marks develop without an obvious cause, which may be described as idiopathic striae.
Studies and clinical observations show that obesity increases the risk significantly; in individuals with obesity, the likelihood of developing stretch marks may reach up to 50%.
Common Factors That Trigger Stretch Marks
Stretch marks may develop due to one or more of the following:
- Rapid or frequent weight gain and loss
- Muscle growth from intense sports or exercise
- Puberty-related body changes
- Pregnancy
- Hormonal imbalance or hormonal shifts
- Use of certain contraceptive pills (in some individuals)
- Obesity
- Long-term use of corticosteroid-containing products
- Naturally thin or sensitive skin
- Cushing syndrome
- Skin injuries
- Low body hydration / insufficient water intake
- Genetic predisposition
- Certain infections
- Treatment methods used in conditions such as HIV/AIDS, typhoid, and tuberculosis
- Chronic liver disease
How Is Stretch Mark Treatment Performed?
Modern aesthetic medicine continues to evolve, and new technologies have made it possible to achieve visible improvement in the appearance of stretch marks. However, an important point should be clearly understood:
Even with the most advanced treatments, the skin may not completely return to its original pre-stretch-mark condition.
Stretch mark treatments aim to:
- reduce visibility,
- improve texture,
- stimulate collagen and elastin production,
- and support skin renewal.
Below are some of the most commonly used stretch mark treatments today:
Fractional Laser for Stretch Marks
Laser technologies are widely used in medical aesthetics. Fractional laser stretch mark treatment is among the most effective and commonly preferred options worldwide.
Fractional laser works by delivering controlled laser energy beneath the skin surface to stimulate tissue renewal in the affected area. The process encourages the skin to produce new collagen, activating the body's natural healing response.
When collagen production increases, the skin's surface becomes smoother and firmer. Because of its skin-tightening effects, fractional laser is also used for skin rejuvenation, scars, and texture irregularities. Many patients report a healthier, more refreshed skin appearance after treatment.
Radiofrequency (RF) Treatment
Radiofrequency-based methods have become increasingly popular and are now used nearly as often as fractional laser.
In RF stretch mark treatment, specialized microneedle or device-based systems deliver radiofrequency energy into the deeper skin layers. The main target is to stimulate collagen-rich tissue and support the formation of healthier skin structures.
The number of sessions depends on:
- the depth of the stretch marks,
- the body region,
- and individual skin characteristics.
Dermatherapy (Dermaroller + Regenerative Support)
Dermatherapy is typically performed using a dermaroller device that contains many micro-needles. The device creates microscopic channels in the stretch-marked area. In many protocols, stem cell extracts or regenerative serums may also be used to enhance the effect.
This method supports collagen production and helps reduce the visual depth of stretch marks. Dermatherapy can be used on many areas, including:
- abdomen,
- hips,
- thighs,
- arms,
- and even the face when indicated.
PRP (Platelet-Rich Plasma)
PRP therapy is used for multiple skin concerns, including stretch marks.
A small amount of blood is taken from the patient and processed in a clinical setting to isolate platelet-rich plasma. This concentrated PRP is then injected into the stretch mark area to stimulate regeneration and accelerate cellular renewal.
PRP can be applied alone, or combined with fractional laser for increased effectiveness.
Creams and Topical Treatments
Medical creams and supportive products may help improve stretch marks-especially when used in early stages. However, topical products alone generally do not provide dramatic results for established stretch marks.
Some commonly recommended active ingredients include:
- Vitamin C
- Glycolic acid
- Tretinoin (doctor-guided use)
Topical options are often used to support device-based treatments rather than replace them.
Stretch Mark Treatment Costs in Turkey
Stretch mark treatment costs vary depending on several factors, such as:
- the chosen method (laser, RF, PRP, etc.)
- the number of sessions required
- the size of the treatment area
- physician experience
- and any supporting products used during the process
For this reason, it is not accurate to provide a single fixed price without an evaluation. After a consultation, the treatment plan is customized and pricing becomes clear. In general, many patients find that these treatments are accessible and manageable within a reasonable budget.
Treatment Process
In stretch mark treatment, the procedure and session plan may vary depending on the selected method (fractional laser, radiofrequency, PRP, or dermatherapy). In most cases, the intervention is performed directly on the areas where stretch marks are visible in order to stimulate collagen production and improve skin texture.
In general, the following points are important to know about the treatment process:
- Patients typically do not feel pain or significant discomfort during the procedure.
- Regardless of the technique used, stretch mark treatment is usually completed in a comfortable and minimally invasive way.
- Results are not immediate; the skin needs time for regeneration and collagen remodeling after the session.
- The time required to notice visible improvement differs from person to person and depends on factors such as skin structure, depth of the stretch marks, treatment area, and the number of sessions.
- The procedure does not require hospitalization or home rest in most cases.
- After the treatment session, patients can generally leave the clinic the same day and return to daily life.
- Following the physician's recommendations and aftercare instructions is essential for achieving smoother healing and more effective results.
For international patients seeking stretch mark treatment in Turkey, scheduling sessions in Tekirdağ (near Istanbul) can be a practical option, particularly for those who prefer a quieter location while remaining close to Istanbul.
After the Treatment
Just like the procedure itself, what to expect after stretch mark treatment may vary depending on the selected method (such as fractional laser, radiofrequency microneedling, PRP, or dermatherapy). However, there are several common points that patients often ask about:
- After the procedure, it takes time for the skin to rebuild itself. Therefore, visible improvement is not immediate, and a waiting period is necessary to observe the final results.
- The number of sessions can differ depending on individual factors such as skin type, the depth of stretch marks, and the affected body area. For this reason, some treatments may require multiple sessions for optimal outcomes.
- Once improvement becomes noticeable, maintaining the results depends largely on lifestyle factors. Patients are generally advised to avoid significant weight gain or weight loss and aim to stay close to their ideal body weight, as large fluctuations can contribute to new skin stretching.
- Stretch mark treatments are designed to improve the appearance of existing stretch marks; however, the procedure does not completely prevent new stretch marks from forming in the future.
