Not at all. Our 0.25mm titanium micro-channels are engineered to bypass the dead stratum corneum without reaching pain receptors. Most users describe it as a light, satisfying exfoliation — nothing like professional microneedling.

Yes. Every roller head and serum ampoule is individually sealed and sterile, intended for one use only. This eliminates any risk of bacterial cross-contamination — a significant advantage over multi-use rollers that can harbour bacteria after repeated use.

Unlike traditional routines where you apply serum separately after rolling, Dr.Nano's integrated device doses the serum automatically as you roll — through the needle head itself. This means the serum enters the micro-channels in real time, ensuring even distribution with zero product waste and no messy extra steps.

Rose-derived PDRN (activates fibroblast proliferation and collagen synthesis), a Cyclopeptide complex (delivers actives past the surface barrier), and Tetrapeptide-15 with Dual Ceramides to soothe skin the moment the micro-channels open.

A reusable dermaroller carries real infection risk if it isn't sterilized properly between uses, and it doesn't deliver serum through the needle itself. Dr.Nano is single-use and sterile per roller, and doses the PDRN/Cyclopeptide serum automatically as you roll — no separate application step.

Yes. The formula contains 0% capsicum, menthol, parabens, or SLS. All ingredients are dermatologist-tested. Tetrapeptide-15 and Dual Ceramides are included specifically to soothe the skin the exact moment micro-needles make contact. The only fragrance is a subtle natural Damask Rose scent. If you have rosacea or eczema, consult your dermatologist before use.

A light, temporary redness or warmth right after rolling is normal and typically fades within 30–60 minutes — this means the micro-channels have opened. If irritation persists beyond a few hours, discontinue use and consult a dermatologist.

As with any skincare device, we recommend consulting your doctor or dermatologist before use if you're pregnant or nursing.

The serum is free of parabens, SLS, capsicum, and menthol, with a subtle natural Damask Rose scent. If you have a known rose or peptide sensitivity, patch-test on your inner arm 24 hours before your first facial use.

1–2 sessions per week is the recommended cadence per treatment area. Each roller is single-use, so a fresh sterile roller is used every session — never reuse a roller across multiple sessions.

You'll experience immediate surface smoothing and hydration within the first 5 minutes of your first session. Deep-tissue structural changes — fading acne scars, restored lip volume, improved hair density — are typically visible after 2–4 weeks of consistent use (1–2 sessions per week).

Cleanse and dry your skin completely — no oils, balms, or makeup. Gently roll the sterile head over the treatment area for about a minute; the serum doses automatically as you roll. Let the micro-channels close naturally over the next 5 minutes before applying anything else. Discard the roller after this single use.

No extra steps are required — the serum is already delivered through the roller. You can follow with your normal moisturizer once the 5-minute window has passed, but avoid active ingredients like retinol or acids on the treated area for the rest of the day.

We recommend waiting at least a few hours after your session — ideally until the next day — before applying makeup, to give the micro-channels time to fully close.
