Microneedling is a cosmetic procedure. It involves pricking the skin with tiny sterilized needles. The small wounds cause your body to make more collagen and elastin, which heal your skin and help you look younger. You might also hear it called collagen induction therapy.
Microneedling may help with issues like:
Hair loss (also called alopecia)
Dark spots or patches on your skin (hyperpigmentation)
Reduced skin elasticity
Fine lines and wrinkles
