Using a single needle for microneedling offers high precision for targeted treatments, such as improving individual acne scars or wrinkles. 

A single needle can precisely target and break down tough, fibrous scar tissue that has formed from acne, surgery, or injury. By creating controlled micro-wounds in the scar, it triggers a wound-healing response that promotes the formation of new, more organized collagen and elastin.

Single needles can be used to treat fine lines and wrinkles in hard-to-reach areas, such as the skin around the eyes and mouth, where larger, multi-needle devices could cause damage. 

A single needle can precisely treat small, concentrated areas of dark spots or uneven skin. tone.
