Stretch marks are dermal scars of multifactorial etiology, for which several treatments have been proposed. Among these is microneedling (MN), a technique that stimulates collagen production. However, the effects of MA alone and in combination with active agents on the length and area of stretch marks and the thickness of the integumentary system are not well understood, as the literature is scarce. Therefore, the objectives of this study were: To assess the effects of MA alone and in combination with active agents (growth factors, hyaluronic acid, and Hydroxyprolisilane CN®️) on clinical parameters (area and length) of stretch marks and morphological parameters (dermal and hypodermal thickness) of the female integumentary system. The sample was randomized into a control group (G1) that did not receive treatment, G2 that received MN alone, and G3 that received MN combined with active agents. Groups G2 and G3 underwent 3 sessions of the protocol with a 4-week interval. Groups were evaluated at the beginning and 4 months after the start of the protocol. Evaluation of the area and length of stretch marks was performed through photography, dermal and hypodermal thickness was assessed via ultrasonography, and satisfaction levels were measured using the Likert scale.
