The A8S works by creating controlled micro-channels that trigger your skin's natural repair response. It's a strong fit for enlarged pores, uneven skin tone, fine lines, skin laxity, post-acne marks, stretch marks, sun-induced hyperpigmentation, and scalp care to support healthier hair follicles. Start conservative with depth and speed, then build from there based on how your skin responds.

The A8S sits at the top of the Dr.Pen consumer lineup. Key differentiators: a high-torque motor with 6 adjustable speed levels for precision control across different skin zones; a wider 0–2.5mm depth range; USB-C fast charging with a built-in battery; and a reinforced 3-slot cartridge lock for a wobble-free fit. If you're coming from an A6S or M8 and want more speed granularity and motor consistency for longer sessions, the A8S is a meaningful step up.

The A8S adjusts continuously from 0 to 2.5mm with 6 speed levels. Practical breakdown: 0.25–0.5mm + Speed 1–2 for everyday serum absorption and fine line care; 0.75–1.0mm + Speed 2–3 for pore tightening and surface pigmentation; 1.25–1.5mm + Speed 3–4 for post-acne marks and firming; 1.75–2.5mm + Speed 4–6 for deeper work (professional guidance strongly recommended at this range). If you're new, always start at 0.25mm / Speed 1 and let your skin adapt before going deeper or faster.

The A8S uses its own proprietary cartridge fitting — it's not cross-compatible with A6S, M7, or other Dr.Pen models. Compatible options: 12-Pin (beginner-friendly all-rounder), 24-Pin (versatile for full-face sessions), 36-Pin (more coverage per pass), 42-Pin (maximum coverage — larger surface area actually makes it more comfortable), and Nano-R / Nano-S (non-invasive serum delivery, safe for frequent use). Match your cartridge to your target area and treatment depth.

For standard microneedling at 0.5mm and above, once every 4–6 weeks gives your skin enough time to complete its full repair cycle. Nano cartridges are the exception — they're safe to use 1–2 times per week for serum infusion. Don't push deep-depth sessions more frequently thinking you'll speed up results. Over-stimulation causes chronic inflammation and will actually slow your progress down.

At 0.5mm and under, most people feel only mild tingling — totally manageable without anything extra. Once you go above 1.0mm, applying a topical numbing cream (5% lidocaine) 20–30 minutes before your session makes a real difference. Wipe it off completely before you start. Worth knowing: higher pin counts like 36-pin and 42-pin actually feel more comfortable because the pressure is distributed across a larger surface area.

Stick with: hyaluronic acid, peptides, ceramides, and EGF. Before your session: double-cleanse, then wipe the treatment area with 70% isopropyl alcohol. After: apply hyaluronic acid serum immediately, skip makeup for 24 hours, and stay out of direct sunlight for 48 hours — SPF is non-negotiable if you're going outside. Hard pass on: retinol, vitamin C, AHAs (glycolic acid, lactic acid), BHA (salicylic acid), and any active exfoliants. Your skin barrier is temporarily open after microneedling, and these will cause unnecessary irritation.

Skip the A8S if you have active acne, open wounds, an eczema flare-up, or rosacea in the treatment area; any active skin infection; if you're currently taking blood thinners or anti-inflammatory medications (wait at least 5 days after stopping); if you're pregnant or breastfeeding; if you have metal implants near the treatment area or are wearing metal jewelry; if you're under 22 (in line with FDA guidance); or if your immune system is significantly compromised.

Cartridges are single-use only — no exceptions. Reusing them dulls the needle tips, increases skin trauma, and seriously raises your infection risk. Before each session: put on gloves, inspect the needle tips for any damage, then soak the needle end in 70%+ isopropyl alcohol for 2–3 minutes (or spray directly). Let it air dry completely before attaching it to the pen. When you're done, seal the used cartridge in a trash bag before disposal — never throw loose needle heads in the open trash.

Completely normal. Mild redness, slight swelling, and warmth are all signs your skin's healing response has kicked in — that's exactly what you want. Shallower sessions typically clear up within 12–24 hours; deeper sessions may keep you pink for 48–72 hours. Post-care: rinse with distilled water or saline, apply a soothing sheet mask or hyaluronic acid serum, skip the gym and sauna for 24 hours, and hold off on makeup for at least a day. If redness hasn't improved after 3 days, or you notice pus, significant swelling, or fever, reach out to a healthcare provider.
