Also called collagen stimulation therapy, microneedling is a cosmetic procedure that inserts tiny sterilized needles into the skin, causing controlled micro-injuries to the skin and triggering your body to rush the natural healing response and regeneration. By stimulating the production of collagen and elastin, it is a great alternative for the body’s natural loss of collagen due to the aging process, since this is an essential protein that helps the skin strength, reduces scars, prevents wrinkles and fine lines, and even hair loss.
