The best microneedling size for acne scars depends on the severity of the scars.
For shallow scars: 0.5mm to 1.0mm needles may be sufficient to stimulate collagen production and improve the appearance of the scar.
For deeper scars: 1.5mm to 2.0mm needles are often recommended to reach deeper layers of the skin and encourage more significant collagen production.
For very deep or pitted scars: 2.5mm or 3.0mm needles may be necessary, but these should only be performed by a qualified medical professional due to the higher risk of complications.
It's important to consult with a dermatologist or other qualified medical professional to determine the appropriate needle size for your individual needs. They will assess the severity of your scars and recommend the best treatment plan.
