Quick Answer
Replace AOS Nano Infusion Pen tips every 4 to 6 treatments, or immediately if the tip appears worn, torn, or clogged. Using a fresh tip each session ensures consistent product delivery and hygiene.
Why Replacement Frequency Matters
The .25mm silicone tip is the only part of the pen that contacts your skin. Over time, micro-tears or residue buildup can reduce precision and increase irritation risk. Replacing regularly keeps the treatment gentle and effective.
If you use the pen on multiple clients (in a professional setting), replace the tip between each client to prevent cross-contamination. For personal use, the 4-6 treatment guideline works well.
Signs You Need a New Tip Sooner
Even within the 4-6 treatment window, inspect the tip before each use. If the silicone looks stretched, has visible nicks, or feels rough to the touch, swap it immediately. A compromised tip can scratch the skin or deliver uneven product.
If you notice the pen is dragging instead of gliding, or if product leaks around the tip edges, those are clear signals the tip has worn out.
Frequently Asked Questions
- How many treatments does one tip last?
- On average, one tip lasts 4 to 6 full-face treatments. For smaller areas like the eye contour, you may get more uses. Always inspect before each session. Track your usage with a simple note or calendar reminder.
- Can I clean and reuse a tip?
- No. The silicone tip is designed for single-use or limited reuse within the 4-6 treatment window. Cleaning with alcohol may degrade the silicone and is not recommended. Replace instead of reusing beyond the recommended limit. Dispose of used tips safely; do not attempt to sanitize for extended reuse.
- What happens if I don't replace the tip often enough?
- An old tip can cause uneven serum infusion, skin irritation, or micro-scratches. It may also harbor bacteria, increasing the risk of breakouts or infection. Sticking to the replacement schedule protects your skin and device performance. If you notice any discomfort or inconsistent results, check the tip first.
- Where can I buy replacement tips?
- AOS Nano Infusion Pen Tips are available in packs of 5. Keep a spare pack so you never run out mid-routine.
