All About Microneedling

What microneedling does

Microneedling (also called collagen-induction therapy or dermarolling) uses lots of tiny needles to make very small punctures in the skin. Those controlled micro-injuries stimulate collagen and elastin production and improve texture, fine lines, and the appearance of scars over time. U.S. Food and Drug Administration+1

Who should NOT do it

Avoid microneedling if you have active acne, eczema/psoriasis flare, rosacea flare, open wounds or cold sores, active skin infection, a history of keloids, or if you’re on certain acne medications (like isotretinoin) — these increase risk of scarring or infection. When in doubt, get medical clearance. Chelsea Westminster Hospital+1

Device & needle length — pick safe options

For at-home use stick to very short needles. Many experts recommend ≤0.25 mm for rollers/pens used at home; these mainly improve product absorption and gentle texture. Deeper needles (0.5–1.0 mm and above) are typically used in clinics by trained pros. Deeper treatments carry higher risks (bleeding, scarring, infection) and should be performed by professionals.

Step-by-step (home-safe approach)

  1. Clean everything. Wash your hands, cleanse your face, and disinfect the device per manufacturer instructions. The FDA and dermatology sources emphasize strict hygiene to prevent infection. U.S. Food and Drug Administration
  2. Patch test. Test the device and any post-treatment product on a small patch (neck or jawline) and wait 24–48 hours for irritation. Healthline
  3. Use gentle technique. Roll or glide in one direction 4–6 passes per area (avoid excessive pressure or repeated passes). Don’t use on active breakouts. Keep movements controlled and brief. Healthline
  4. Apply soothing serums (optional). After treatment, apply a simple, non-irritating hydrating product (e.g., hyaluronic acid) if your skin tolerates it. Avoid active ingredients that irritate (strong retinoids, vitamin C serums at high concentrations) for at least 24–72 hours. Byrdie+1
  5. Protect from sun. Skin is extra vulnerable after microneedling — use a broad-spectrum sunscreen daily and avoid direct sun for several days. Chelsea Westminster Hospital

Aftercare & frequency

Expect redness, mild swelling, and tightness that usually settles in days. Keep skin clean and avoid heavy makeup for 24 hours. Cleveland Clinic

For short home needles (≤0.25 mm) many people treat every 1–2 weeks; for professional deeper treatments spacing is weeks to months. Don’t overdo it — the skin needs time to heal. Verywell Health+1

Risks to watch for

Infection, prolonged redness, hyperpigmentation, scarring, and allergic reactions to topical products are possible — improper cleaning, using the device on broken or infected skin, or using needles that are too long for home use raise the risk. If you see signs of infection (increasing pain, pus, spreading redness, fever), seek medical care. U.S. Food and Drug Administration+1

Bottom line

Microneedling can help with texture, fine lines, and mild scarring, but safety matters more than speed. If you want deeper, faster results or have significant skin concerns, book a licensed clinician. If you plan at-home treatments, use short needles, follow strict hygiene, and talk to a dermatologist if you have any risk factors. U.S. Food and Drug Administration+1
