How Does Medical Needling Work?
•
0.5mm – 3.0mm
•
Uses very fine, surgical stainless steel needles to make channels into
the epidermis and dermis to release growth factors
•
Promotes scarless healing and deposition of normal woven collagen
rather than scar collagen
•
Similar to Fraxel, without the negative loss of dermal papillae,
potential destruction of melanocytes, abnormal collagen, coagulated
growth factors
•
Allows 80% more product into the skin (compared to 7-10% normally)
1.10
Collagen Induction Therapy
Microinjuries allow for release of serum
containing cytokines and growth factor*

Optimizing the Melanocyte
Unfortunately, melanocytes lie between
most anti-aging treatment modalities and the
targeted fibroblasts, and are often sacrificed in
overzealous attempts to obtain greater injury
through aggressive injury.

Optimizing the Melanocyte
5 intervention points:
• Block UV radiation
• Block Melanin Stimulating Hormone (MSH) before it
stimulates the keratinocytes and melanocytes
• Inhibit tyrosinase, the enzyme needed to form
melanin in the melanosome
• Interfere with L-Dopa, the building blocks for
pigment in the melanosomes
• Interfere with transfer of pigment from the
melanosome to the keratinocyte

actually optimizes cell function,
making it the ideal treatment for all
skin types.

Preserve the Epidermis
• Epidermis is complex, highly specialized organ
• 0.2mm thick
• Only protection from the environment
Preserve the Epidermis
Traditional Ablative Therapies
•
•
•
•
Damage the skin to cause fibrosis of the papillary dermis
Epidermis thinned
Dermal papillae destroyed
Severe changes in dermis
Preserve the Epidermis
Resultant Collagen from Ablative Therapies:
• Parallel (scar) orientation rather than normal, lattice network
• Scar collagen will be resorbed by the body over time – all
scar collagen is
• Fine wrinkles will be visible due to thinned epidermis and
lack of dermal papillae
1.12
Collagen Induction Therapy
CIT Promotes deposition of fresh new collagen
without scar formation*
Left, before CIT. Right, six months after CIT, more collagen (pink) and
elastin (brown) can be detected. Estimated > 400% more collagen and
improved epidermal/dermal thickness
*Fernandes, D. OralLMaxillofacial Surg Clin 2005; 17:51-63
Preserve the dermal papillae
• Exchanges oxygen, nutrients, and waste products
between the epidermis and dermis
• Provides strength between the epidermis and dermis to
prevent the deterioration and separation of the
dermal/epidermal junction, which presents as wrinkles
Break Down Scar Tissue
Allows the epidermis to lift and lay flat,
eliminating any shadowing
Induce Regenerative Healing
• Collagen forms from the base upwards
• Opposite of Regenerative Healing is “Cicatricial
healing”: leaves a scar when the formation of new
connecting tissue overlies a wound
1.10
Microneedling Meets All Goals
Optimize cell function
Preserve integrity of the epidermis
Strengthen dermal/epidermal junction
Preserve dermal papillae
Break down scar tissue
Release epidermal growth factors
Increase natural collagen: transforming growth factor ß3
(TGF-ß3)
Induce regenerative healing

Introducing SkinPen
2013: SkinPen modernizes microneedling
•
•
•
•
Stainless steel, cordless design
Single, use disposable Advanced Microneedle Cartridge
Minimizes epidermal destruction while delivering over
1400 microchannels per second
Ideal for clinical practice
Fine lines or moderate
wrinkles
Diminished skin texture,
tone and color
Atrophic acne scars
Stretch marks
Traumatic scars
Photo aging
Dr. Des Fernandes – Topical A & C
Pre-treats patients with topical A and C three weeks to three month prior to
needling.
•
Vitamin A is essential for the normal physiology of the skin and for
collagen preservation; maximizes collagen production and the
skin will heal as rapidly as possible
• Vitamin C needs to replaced daily to ensure for natural protection and repair
of DNA; essential for the production of normal collagen
1.15
Microchannel Formation
For dermal rollers,
the number of
microchannels
increases as a
function of the
number of
passes made
1 pass
3 passes
5 passes
*Figure from: The AAPS Journal, Vol. 13, No. 3, September 2011
10 passes
15 passes
1.16
Microchannel Formation
For SkinPen, the number of microchannels depends on how quickly
you move the SkinPen across the surface of the skin.
► Needles cycle at 142 Hz or 142 “stamps”/second, potentially
creating 1704 microchannels/second when moving the skin pen
► Slower movement at a rate of 1 cm/second, you can create
roughly 4858 microchannels/ cm2 of skin*
► Faster movement at a rate of 3 cm/second, you can create
roughly 1621 microchannels/ cm2 of skin*
► The SkinPen produces significantly more microchannels with one
pass than created by a dermal rollers after many passes!
*Needles are ~1 mm apart (1000 microns) and the cartridge head has a diameter of 3.5 mm
3.4
Recommended Needle Depth
Needle depth is contingent on:
Thickness of dermis in area to be treated:
The dermis of the face is variable, typically no deeper
than 1.5 mm
Dermis in other areas of the body may be thicker or thinner,
with the dermis of the back typically the thickest (~3 mm)
Reason for Treatment:
Facial rejuvenation for improvement of skin texture of fine
lines will require less penetration
Improvement of scar tissue will require a more aggressive
treatment and therefore deeper penetration

Why SkinPen?
• Stainless steel, cordless design
• The most advanced microneedle cartridge on the market:
Bio-Sleeve technology eliminates cross-contamination and protect the pen
12 medical grade steel, 32 gauge needles to reduce epidermal destruction for
superior results and positive patient experience
Exhaust port to reduce suction and risk of broken capillaries

Treating Hyperpigmentation
5 intervention points:
1. Block UV radiation
2. Block Melanin Stimulating Hormone (MSH) before
it stimulates the kertinocytes and melanocytes
3. Inhibit tyrosinase, the enzyme needed to form
melanin in the melanosome
4. Interfere with L-Dopa, the building blocks for
pigment in the melanosomes
5. Interfere with transfer of pigment from the
melanosome to the keratinocyte
Topicals: Increase collagen synthesis
• Amino acids such as Proline and Lysine
• Copper peptides
• Peptides such as palmitoyl oligopeptide, Matrixyl 3000, palmitoyl
tetrapeptide 7, kinetin
• Zinc
• Bioflavinoids: plant-derived antioxidants such as grape seed
extract/resveratrol, green tea extract
• Stem cells
• Omega 3 & 6

Clinical Study: Scars
Microneedling offers a simple and safe modality
to improve the appearance of acne scars without risk
of dyspigmentation in patient of all skin types
60 patients of skin types phototype I to VI were treated with
microneedling for treatment of acne scars
Three treatments at monthly intervals.
Evaluated by using a Global Aesthetic Improvement Scale
(GAIS), and analyzed statistically by computerized image
analysis of the patients’ photographs.
Average reduction of 31% of scarring.
No short- or long-term dyschromia was observed.
Fabbrocini G, et al.. J Dermatolog Treat. 2012 Dec 8. [Epub ahead of print].
Stretch Marks
• Difficult to treat
•
•
Epidermis is atrophied and support structure beneath it is compromised
Melanocytes are sparse or absent, distance to cover is too great for migration
• Needling:
•
•
Improves density of the epidermis through release of epidermal growth factor
Considered to be the most effective solution for stretch marks
• Important to not overpromise and under-deliver results
Clinical Study: Stretch Marks
Treatment of striae distensae using needling therapy: a pilot study.
• 16 Korean volunteers
• 3 microneedling treatments at 4-week intervals
• Assessed by pre and post-treatment clinical photographs, skin biopsies,
and patient satisfaction scores.
Dermatological Surgery 2012 Nov:38(11): 1823-8
Clinical Study: Stretch Marks
Results:
7 patients (43.8%): marked to excellent improvement
9 patients: minimal to moderate improvement
Patient Satisfaction Scores:
6 patients (37.5%): highly satisfied
8 patients (50%): somewhat satisfied
2 patients (12.5%): unsatisfied
No significant side effects except mild pain, erythema, and spotty bleeding.

Rosacea
• Stimulates EGF (epidermal growth factor) to increase density of
epidermis, lessening appearance of vessels under the skin and overall
redness
• Strengthens collagen in vessel walls and connective tissue that supports
the vessels
• Increases Platelet GF which attracts monocytes into the wound which
release interleukin 10 (anti-inflammatory cytokine)
• Increases availability of cell nutrients and antioxidants
