Microneedling is one of the most requested treatments in UK aesthetic clinics, and the pen is the reason it is so accessible: compact, versatile and far less expensive than energy-based devices. But the market is crowded with near-identical pens, many designed for home use. This guide sets out what to compare before buying a professional microneedling pen.
Professional pen vs home device
The difference is not the look of the device; it is what it can do safely and consistently.
- Depth range. Home rollers and pens generally stop at 0.25–0.5 mm, enough to improve product absorption. A professional pen adjusts up to 2.0–2.5 mm for collagen induction, scarring and stretch marks.
- Consistent penetration. A stable motor and accurate depth setting mean every pass reaches the same depth. Inconsistent pens drag or skip, causing uneven results and unnecessary trauma.
- Sterile, single-use cartridges with a design that limits fluid flowing back into the pen — essential for infection control between patients.
- Quality system. Look for manufacturing under a recognised medical device quality system such as ISO 13485, and clear technical documentation.
Depth by indication: a working guide
- 0.25–0.5 mm: product delivery, periorbital area, forehead, sensitive or thin skin.
- 0.5–1.0 mm: general rejuvenation, texture, enlarged pores, fine lines and pigmentation protocols.
- 1.0–1.5 mm: deeper lines and mild atrophic scarring on thicker areas such as the cheeks.
- 1.5–2.5 mm: acne scarring and stretch marks on the body — only for practitioners trained in deeper treatments, with appropriate anaesthesia and aftercare.
Always adjust to skin thickness, the area and the patient's response, and start conservatively with new patients.
Cartridges and running costs
The pen is a one-off purchase; cartridges are a cost per treatment. Check which cartridges a pen accepts, whether they are individually sterile-packed, and their needle configuration. A 12-needle cartridge, such as Medical Pen Tips, is a versatile standard for face and body. Use a new cartridge for every patient and every session.
What to apply during treatment
Microneedling opens temporary channels in the skin, so anything applied during and immediately after treatment reaches deeper layers. Only use sterile products formulated for this purpose — never ordinary skincare containing fragrance or preservatives designed for intact skin. Skymedic's deep serums (Hyalurox, Colagenox, Fotoskinox and Hairox) are designed for drug-delivery protocols on the face and scalp, and the EXO OX professional vials for regenerative protocols.
Aftercare that protects results
- No make-up for 24 hours, and no actives such as retinoids or acids for several days.
- A gentle, hydrating routine and broad-spectrum SPF every morning; Fotoskinox Cream SPF 50+ is designed for post-procedure skin.
- Typical redness lasts 24–72 hours depending on depth. Treatments are usually spaced four to six weeks apart, in courses of three to six.
Our post-procedure recovery protocol covers aftercare in detail.
UK regulation, insurance and training
Microneedling is a skin-piercing procedure. Depending on where you practise, you may need registration or a licence from your local authority, and the Government is introducing a licensing scheme for non-surgical cosmetic procedures in England. Before you treat, check the current requirements with your local authority, make sure your insurance covers microneedling at the depths you intend to use, and keep training records up to date. Skymedic Academy runs hands-on courses in London.

Frequently asked questions
Is a microneedling pen better than a derma roller?
For professional treatments, yes. A pen penetrates vertically at a controlled depth with less tearing, uses a fresh sterile cartridge every time and adapts to small areas around the eyes and nose.
How many treatments does a patient need?
Usually a course of three to six sessions, four to six weeks apart, with maintenance once or twice a year.
Can I combine microneedling with other treatments?
Yes — with LED, peels on separate days, and regenerative serums. Radiofrequency microneedling is a separate, energy-based treatment with its own training requirements.
Who should not have microneedling?
Patients with active acne or infection in the area, open wounds, a history of keloid scarring, or those on medication that impairs healing. Take a full medical history before every course.
