Microneedling Cartridges
Match your cartridge to your skin concern for the best results:
Nano — Surface-level, no downtime. Ideal for product absorption, brightening, and sensitive skin. 11 Needle — Precision tip for targeting deep scars and wrinkles. 12 Needle — Versatile all-rounder for general rejuvenation and texture improvement. 16 Needle — A wider needle cluster that covers more surface area per pass, making treatments faster. 18 Needle — Efficient and versatile for when comfort and results matter. 36 Needle — Maximum coverage, best for larger areas and gentle stimulation.
Always match your cartridge to your Dr. Pen model. Read our FAQ guide for needle depth and speed guidance.
Replacement Cartridges for Every Skin Concern
Always use a fresh cartridge for every microneedling session. A new needle head ensures optimal sharpness, consistent depth, and hygienic treatment — all of which directly impact your results. Dull or reused needles create uneven micro-injuries, increase discomfort, and raise the risk of skin irritation. Sandy recommends replacing your cartridge every session, without exception.
