Micro needling in treatment of stretch marks

Abstract

Striae distensae: Are scars on the skin that have an atrophic linear depression, produced by stretching of the skin. Causes include puberty, pregnancy, mechanical stress, hormonal, genetic role and cachectic states and medications. Treatment occurred by enhancing collagen production or by reducing vascularity. Micro needling (MN) is a modern therapeutic option in dermatology. MN instruments include automated micro needling device, micro fabricated microneedle, derma-stamp and microneedle derma roller. Applications of MN in dermatology include transdermal delivery of drugs, scar reduction, skin rejuvenation, androgenic alopecia and alopecia areata, post acne scars pigmentation-Melasma and periorbital hyper melanosis, actinic keratoses, post-surgical scars, vitiligo and miscellaneous conditions. The benefit of MN is that individuals don't have open wounds, necessitating only a brief recovery period. But it has some adverse events such as potential erythema and irritation. Patients on anticoagulant therapy, herpes labialis, active acne or any other local infections have contraindications of using micro-needling.
