Since you now have a basic understanding of what microneedling is, let's talk about the different types of microneedling treatments that are available. There are two main types: mechanical and fractional radiofrequency. -Mechanical microneedling: Also known as derma rolling, this type of microneedling uses a device that contains several small needles. The device is rolled over the skin, puncturing it multiple times. The main target of this type of treatment is the epidermis, or outer layer of skin. -Fractional radiofrequency microneedling: This type of microneedling uses heat to stimulate the growth of elastin fibers and new collagen. A device that emits radiofrequency waves is passed over the skin, penetrating deeply into the dermis. This type specifically targets the deep layers of skin, making it an ideal choice for treating wrinkles and scars. If your skin needs one particular type of treatment more than another, your dermatologist will likely recommend a specific type of microneedling. But in general, a combination of both types is usually the best way to go.
