Background: Striae distensae (SD) or stretch marks, a common condition causing significant cosmetic concern and distress, are linear dermal scars associated with epidermal atrophy that occur due to overstretching. Recently, micro-needling with dermapen is considered as one of the therapeutic modalities for SD. Also, plasma skin regeneration with plasma jet has been recommended as an effective method for the treatment of SD.
Aim: The aim was to compare between the efficacy of both methods in the treatment of SD.
Methods: This study included 30 patients with striae distensae. Body was divided into two halves; one was treated with plasma jet for two sessions with 1 month interval and follow-up one month after the last session and the other half was treated with dermapen for four sessions with two weeks interval and follow-up one month after.
Results: There was no statistically significant difference (p- value >0.05) between dermapen and plasma jet procedures as regard to width, Total Atwal Score, Atwal score component, score of erythema, and skin texture after treatment. There was high statistically significant difference (p value <0.01) between dermapen and plasma jet as regards pain with higher values with plasma jet while there were statistical higher values concerning hyperpigmentation and erythema with dermapen. There was high statistically significant difference (p value <0.001) between width of striae before and after treatment with dermapen.
Conclusions: Both lines of treatments are effective and promising therapeutic modalities for striae distensae with minimal side effects.
