Microneedling: what it is, how it works, and why quality matters

Microneedling is one of the most rewarding treatments I offer. Done well, it can transform texture, scarring and firmness in a way few things can. But it’s also a treatment where the gap between “done well” and “done badly” is enormous, and that’s exactly why I want you to understand it properly before you book, anywhere.

So here’s the complete picture: what microneedling actually is, why quality matters so much, what a good treatment should and shouldn’t feel like, and how to care for your skin afterwards.

What microneedling is, and how it works

Microneedling, also called collagen induction therapy, is a non-invasive treatment that creates tiny, controlled micro-injuries in the skin. Those signals wake up your fibroblasts, the cells that make collagen and elastin, and set off your skin’s natural repair process. The key word is controlled. This is gentle, precise stimulation, not aggressive puncturing.

Why it should never be done cheaply

There are three real costs behind a proper treatment. Good, regulated needle cartridges cost around £20 each, and poor ones can tear the skin and cause lasting sensitivity and scarring. Professional serums cost roughly £20 a vial because they’re sterile and safe to be infused into the skin, unlike cheap cosmetic-grade products that can cause irritation and infection. And the person holding the device needs proper training, because this is an advanced treatment, not a basic facial.

What microneedling should never do

A well-judged treatment should not make you bleed heavily, should not be painful, and should not leave you inflamed or scarred. If any of those happen, something has gone wrong.

The right depth

Depth is matched to the goal: around 0.25mm to 0.5mm for general rejuvenation, and 1mm to 1.5mm for acne scarring, which needs careful, experienced technique. It’s not one setting for everyone.

What it can do for your skin

Boost collagen and elastin

Soften fine lines and wrinkles

Even out tone and texture

Refine the look of pores

Help your skincare absorb and work harder

Aftercare that protects your results

For the best outcome, keep skin clean and hydrated, wear SPF daily, and use gentle, soothing products with ingredients like aloe vera, ceramides and peptides. In the first day or two, skip makeup for 24 hours, avoid exfoliation for a few days, stay away from saunas, hot showers and intense workouts, and leave vitamin C, retinol and glycolic acid for 48 hours.
