Stretch marks – medically known as striae distensae – develop when connective tissue is overstretched due to rapid growth or hormonal changes. They are particularly common during or after pregnancy, with significant weight gain, rapid muscle development, or during puberty. The affected areas of skin – typically the abdomen, thighs, hips, breasts, and upper arms – often appear thin, torn, and irregular. They lose elasticity and, for many affected individuals, cause an aesthetic problem that can also affect self-esteem. While creams and laser treatments often show only limited results, a regenerative therapy is increasingly gaining attention: PRP.
PRP as a natural regeneration method
Platelet-rich plasma (PRP) is a concentrate derived from the body's own blood that is rich in growth factors and bioactive proteins. These components play a key role in tissue regeneration, new collagen formation, and improving skin texture. The goal of PRP therapy for stretch marks is to revitalize the affected skin structure, stimulate cell metabolism, and sustainably improve skin elasticity and thickness.
Why is PRP particularly suitable for stretch marks?
Unlike many superficial treatments, PRP works in the deeper layers of the skin. The therapy targets the area where the skin's structure has been damaged by overstretching. The injection or introduction of PRP causes a targeted activation of fibroblastic cells, which are responsible for the production of collagen and elastin. This effect leads to visibly firmer skin, a refined appearance, and a significant reduction in stretch marks over a period of weeks.
PRP can achieve excellent results, especially on fresh, reddish-purple stretch marks. However, the method also shows success on older, whitish stretch marks—especially in combination with microneedling or radiofrequency therapy.
Treatment process and tolerability
The PRP treatment begins with a simple blood draw. The resulting plasma is processed in a special centrifuge and then either finely injected or applied to the skin using a microneedling device. The procedure is minimally invasive, low-risk, and virtually painless. Since only the body's own substances are used, there is virtually no risk of intolerance or allergic reactions. Patients can return to their daily lives immediately after the treatment. Occasionally, slight redness or tightness may occur, which quickly subsides.
Who is PRP treatment suitable for?
PRP is suitable for all skin types and is particularly recommended:
-
For newly developed stretch marks
-
For old, faded stretch marks with thin skin structure
-
After birth for supportive recovery
-
After significant weight change
-
As a complement to other skin-tightening therapies
How many sessions are necessary?
Typically, a course of three to five sessions, spaced four weeks apart, is recommended. Initial improvements are often seen after just the second treatment. Because the treatment works at the cellular level, the results build with each session. After the initial treatment, an annual top-up may be beneficial to maintain the achieved skin condition over the long term.
PRP in combination with other procedures
Even better results can be achieved when PRP is combined with other regenerative methods. The combination with:
-
Microneedling: supports the absorption of PRP and also promotes collagen regeneration.
-
Radio frequency: improves deep penetration and skin tightening.
-
CO2 laser: PRP can help as a follow-up treatment to reduce skin irritation and accelerate the regeneration process.
Conclusion
Stretch marks don't have to be a permanent nuisance. PRP therapy offers a modern, effective, and natural treatment method that works without surgery or chemical additives. By specifically stimulating the body's own healing processes, the skin is strengthened from within, the appearance of stretch marks is improved, and the tissue is visibly tightened. Anyone seeking a gentle yet lasting solution for smoother, more even skin will find PRP a compelling answer.
