Microneedling boosts collagen production by creating tiny micro-channels in the skin, which signal the body to begin its natural repair response. When this happens, fibroblast cells become more active and start producing fresh collagen and elastin. Over time, this helps improve skin texture, firmness, and elasticity. It can also soften fine lines, reduce acne scarring, and give the complexion a more youthful appearance. Devices like the dr pen ultima a6 make this process more precise and effective, offering adjustable needle depths and smooth operation for a comfortable treatment experience.
