DDSPM vs. Metal Needle Comparison

INDICATORTRADITIONAL METAL NEEDLE PMUDDSPM
COLOR RETENTIONProne to pigment migration,
blurring, and discoloration
Designed for precise pigment placement
and long-lasting color retention
PAIN & COMFORTMay cause greater discomfort
and often involves topical anesthetics
Designed for a more comfortable procedure
with reduced reliance on topical anesthetics
ANESTHETIC USEOften requires repeated anesthetic applicationDesigned to reduce procedure interruptions
associated with anesthetic application
TIP STRUCTUREConical tip with no defined side-edge
cutting structure
Faceted side-edge tip with sharp cutting
edges on the sides
DEPTH CONTROLNo depth-limiting base; penetration depth
relies on manual control
315 μm preset safe depth for more
controlled penetration
TIP DIAMETERConventional metal needle tip ~15 umDDSPM Non-Metallic Needle Tip ~0.1 um
SURFACE FINISHSurface may have burrs due to the
grinding process
Ra < 60 nm for a smoother tip surface
MATERIAL HARDNESSD4.5 Moh hardness steel (original specification;
verification required)
D10 MOH — double hardness (original
specification; verification required)
SKIN IMPACTRepeated passes and excessive penetration
may increase tissue trauma
Designed to minimize unnecessary skin
trauma through precise application
COLOR FIDELITYExcessive penetration may compromise color
clarity and consistency
Designed to support clear, vibrant, consistent
color results
OPERATIONAL
EFFICIENCY
Repeated passes and anesthetic application
may extend procedure time
Designed to streamline application and
reduce unnecessary repetition
ARTIST EXPERIENCEDemands extensive practice to develop
consistent hand control
Scientific Precision. Less Subjective Judgment.
Less Wasted Practice.
