Does microneedling improve acne scars? What 12 randomised trials found

What question did the researchers ask?

The analysis compared microneedling monotherapy with other acne-scar treatments and separated conventional microneedling from fractional radiofrequency microneedling.

What did they actually find?

Conventional microneedling showed objective scar improvement in the pooled analysis. Satisfaction was generally similar to comparator treatments, and the pooled pigmentation outcome favoured microneedling.

What should you keep in mind?

Results were specific to acne scars, and some pooled comparisons were not statistically significant. Scar pattern, skin type, device depth and course still influence outcome and risk.

What does this mean for a Highfield consultation?

This evidence concerns acne scarring; skin rejuvenation and other indications may have different evidence. We consider that finding alongside independent guidance, your medical history, examination and priorities. It can support a better-informed decision, but it cannot promise a personal result or decide whether treatment is suitable.
