Microneedling is an aesthetic treatment that uses fine needles to stimulate collagen production in the skin, recommended for various purposes such as removing acne scars, stretch marks, wrinkles and sagging. Before the procedure, care is recommended such as applying specific products and analyzing allergies. During the treatment, the professional cleans the skin, applies local anesthesia and slides the microneedling device over the area to be treated. After the procedure, the skin may become sensitive, requiring care such as avoiding sun exposure and the use of chemical products. There are some contraindications for microneedling, on skin with active acne, herpes infection, use of anticoagulant medications, among others. Always consult a professional for specific and safe guidance.
