Microneedling is a treatment that
has recently become popular.
Numerous brands of manual and
electronic devices for this modality
have appeared at trade shows and are
attracting attention in the skin care
profession. Also known as collagen
induction therapy, dermal needling,
dermal rolling, and skin needling, the
treatment utilizes very small needles to
stimulate the skin.
These tiny needles are set into a small roller that is
passed over the skin, or in an electronic device that moves
the needles up and down as they move across the skin.
While different sizes are available, those
used by estheticians outside of a medical
setting have a diameter of 0.25 millimeters
or less (ideally, they should be as fine as
0.07 mm) and a length of 0.25–0.5 mm.
Devices with a needle length above 0.5 mm
(sometimes going as high as 2 mm) are
for medical use only, as they penetrate the
papillary dermis.
What Is It Used For?
Microneedling is currently used to
improve the appearance of wrinkles and
treat acne scarring, hyperpigmentation,
loss of elasticity, and photo damage.
When microneedling was invented,
the main goal was to allow topicals used
during the treatment to penetrate deeper
into the skin. Obviously, this can lead to
problems if incorrect products are applied,
