This keeps the solution airtight and sterile ensuring no risk of cross-contamination and maintaining consistent levels of reliability during delivery.  Patients can safely use the 0.5mm needles to apply solution into their own scalp and skin at home. Depths of 1mm, 2mm, and 3mm are recommended to be administered in-clinic, by trained staff. The circular needle tip plate allows for contouring during injection for hard to reach areas such as under eyes and cheek contours.
