Microneedling is a procedure in which an instrument with multiple rows of tiny needles is rolled over the skin to elicit a wound healing response and stimulate collagen production to reduce the appearance of atrophic acne scars in people with darker skin color. Notable adverse effects of microneedling include postinflammatory hyperpigmentation and tram track scarring (described as discrete slightly raised scars in a linear distribution similar to a tram track). The latter is thought to be primarily attributable to improper technique by the practitioner, including the use of excessive pressure or inappropriately large needles.
My beauty cabinet is full of cleansers from some of the priciest boutique brands, but the cleanser I have used every day for years doesn't cost $60 or even $30, it costs $6 at the average drugstore. When my friend Laura spotted my bottle of Purpose Gentle Cleansing Wash in my bathroom, she emerged laughing. She couldn't believe THIS was my cleanser of choice. I had to explain that you don't need a lot of bells and whistles in a good cleanser.
