This can be a game-changer if you’ve recently lost weight and have deep stretch marks on your arms and breasts. If you have any sunspots or acne scars in the area, PRP injections can also help diminish them.
Can PRP Microneedling be used to treat scars as well?
Yes! PRP for stretchmarks as well as PRP micro-needling can be used and is effective in the treatments of scars and scar tissue. Research has shown that there is a significant improvement of scar tissue after multiple PRP therapy sessions. Typically scan tissue is less inflamed appearing and visible after multiple treatments.
A study performed by Ahmed and Mostafa included 45 patients with skin types III and IV (Fitzpatrick) with both striae albae (scar tissue) and striae rubrae (stretch marks). They were then grouped into two groups evenly with 10 scar tissue patients and 5 stretch mark patients per group (15 patients each). Group A was treated with a laser therapy called carboxytherapy or CO2 laser), group B received treatment with PRP, and group C received radiofrequency therapy (RF).
The treatments were performed every week for a total of 5 sessions. The study revealed improvement in all three groups. Patients who underwent PRP treatments had a less visible scar and stretchmark appearance with thicker and healthier appearing skin. Histopathological findings under the microscope for scars, 3 months after treatment with PRP demonstrated an increase in epidermal thickening with formation of rete ridges and decrease in perivascular infiltrate. Additionally, there was an increased number of collagen fibers and elastic fibers. The fibers were longer, thicker, and more evenly arranged. [1]
Platelet-rich plasma for stretch marks – Review of medical literature
A review study published in the International Wound Journal revealed that there were clinical and subjective improvements for the treatment of stretchmarks or striae distensae for patients that underwent this novel therapy. The main findings of the study were that multiple treatments with platelet-rich plasma showed an increase in epidermal thickness, rete ridges formation, as well as collagen and elastin formation. There was also a decrease in the inflammation and appearance of stretchmarks.[2]
In another study, Ibrahim et al treated 68 patients with different degrees and severity of stretch marks with PRP therapy. Lesions were randomized to treatment with either intradermal application of PRP (group I), microdermabrasion (group II), or both microdermabrasion and intradermal injection of PRP (group III). Treatments with PRP were performed every 2 weeks for a total of six sessions or until the patient was satisfied with the results.
Results revealed that both subjectively and objectively there was significant improvement of the appearance of stretch marks treated with PRP or both PRP and microdermabrasion compared to those treated with microdermabrasion only. Under the microscope there was improvement of epidermal atrophy, increase in epidermal thickness, and increase in rete ridges formation. There was also a decrease in perivascular inflammatory infiltrate after PRP treatment. Most importantly, elastic fibers increased in number and became thicker, longer and evenly arranged. [3]
Hodeib et al investigated 20 patients presenting with scar tissue and compared PRP injections on the right side of participants’ abdomen (group A) as well as CO2 laser therapy on their left (group B). Treatments were repeated every 3–4 weeks for 4 sessions in total. Results of the study demonstrated significant improvement in striae albae or scar tissue after treatment in both groups. Side effects after PRP were pain during injection in 50% of the patients and redness or bruising in 40%. [4]
