If you feel self-conscious about your stretch marks and hesitate to wear a swimsuit or a skirt, don’t worry. Dermatology has developed a particularly effective solution against stretch marks: laser therapy.
Laser treatment for stretch marks: how does it work?
Stretch marks appear as streaks that affect certain areas of the body. The hips, buttocks and breasts are particularly prone to these dermal lines.
Stretch marks result from the tearing of the dermis, the skin layer located between the epidermis and the hypodermis. The dermis contains collagen, a molecule that gives skin its elasticity and resistance to tearing. The changes a woman’s body can go through over the course of her life make her vulnerable to these cosmetic concerns in two ways:
- Pregnancy or weight gain cause the skin to stretch. Despite the resistance provided by collagen, the dermis can tear, and as the skin relaxes, these scars — initially purplish — gradually fade to a whitish tone.
- A hormonal imbalance can lead to increased cortisol levels. Excess cortisol reduces collagen production, making the skin particularly vulnerable to tearing. Stress, for example, is a known trigger for cortisol production.
A laser-based stretch mark therapy is the most suitable solution for reducing these marks. Studies (1) have already demonstrated the effectiveness of this method, which involves heating the skin with a beam of light to stimulate collagen production. By targeting the affected area, the dermatologist can reach the dermis and significantly alter cellular activity to achieve the desired results.
Depending on the nature, shape and extent of the skin condition, various approaches may be recommended. This decision rests with the healthcare professional, who will determine the most appropriate method — whether to break down tissue, restore pigmentation to the affected area, or firm the skin. The wavelength of the beam determines its effects.
The different types of lasers for stretch marks
Non-ablative fractional lasers
The Icon laser is a widely used option. It is a gentle method that does not cause lesions on the skin — meaning the light beam does not create holes or scabs within the skin tissue.
It triggers an inflammatory response in the dermis, which boosts collagen production. This helps firm the skin and improve pigmentation in the affected area. This technique is well suited to minor white-toned lesions, as it does not deeply alter the dermis.
Ablative fractional lasers
This method is more intensive than the previous one, as it involves destroying microscopic areas within the dermis while leaving healthy cells nearby intact. The cellular regeneration of these healthy zones fills in the dermal damage caused by the treatment, progressively reducing the appearance of stretch marks.
However, side effects are more pronounced than with a non-ablative beam, and may include redness, swelling or even scabbing. This method is ideal for treating older, whitish marks.
Vascular lasers
These are used on recent lesions that still have a purplish hue. The light beam heats the areas where blood vessels are discoloured, causing them to coagulate and gradually disappear over successive sessions.
How long does laser treatment take — and what does it cost?
Eliminating the stretch marks that affect your confidence takes time and comes at a cost. The treatment process involves multiple sessions spaced several weeks apart, allowing the skin to recover between each exposure to the light beam.
Note that the cost of these stretch mark solutions depends on the nature and size of the area to be treated. For recent, small lesions, a session may cost less than €100, with a total investment of a few hundred euros. For extensive or long-standing stretch marks, however, the total cost can reach several thousand euros.
To reduce the appearance of stretch marks, there are fortunately many other solutions available. One effortless option is simply wearing the Cellublue Shorty Expert Vergeture.
Worn for 8 hours a day, 6 days a week, the natural active ingredients in the Shorty help reduce stretch marks on the inner thighs, sides and buttocks — without squeezing or compressing the skin.
