• Thermal damage
– Collagen contracture
– Inflammation
• New extracellular matrix
TRL Er:YAG Combination Therapy
Short pulse width and high fluence
for ablation – heat is ejected along
with ablated tissue
Fluence

Mechanisms of Skin Improvement
Following Laser Resurfacing
• Collagen shrinkage
– Thermal desiccation
– True shrinkage?
– Temporary but may provide initial matrix for
collagen production
Mechanisms of Skin Improvement
Following Laser Resurfacing
• Fibroblast migration
– Immunofactors
– Mast cells
• Vasoactive substances
– Macrophages
• angiogenesis
Prior to Laser Resurfacing
•Thin grenz zone
•Solar elastosis
After Laser Resurfacing
• Thickened epidermis
• Thickened grenz zone
• Neocollagenesis
– Parallel collagen fiber
orientation
– Reduced solar

Wavelength: 2940nm Er:YAG
Spot size: 430 µm
Coag Levels 0, 1, 2, 3 (0 to 150 um)
Depth: 25 – 1500 µm
Density: 5% and 11%
– two most frequently used densities with ProFractional
• Scanned area: 6x6 – 20x20 mm
• Fast treatment speed
– 2 to 3 times faster than first generation ProFractional
Parameters
• Spot Size
• Coag Level
– Degree of thermal damage
• Depth of ablated column
• Density
• Depth of MLP
Spot Size
• 430u vs 250u
– Is spot size clinically relevant?

Spot Size Conclusions
• 430u vs 250u
– No difference in healing times
– Slight increase in patterning by 1-2 days if
examined by magnification
– Larger size had slightly better result

ProFractional-XC – Tunable Coag
Optional and User-Controlled Coagulation
• Control the amount of heat delivered independent of ablation depth
• YSGG and CO2 lasers can only deliver ablation in conjunction with
thermal injury
• Optimize the ratio of ablation and thermal zone
• Increase coagulation for more collagen production

ProFractional-XC – Emulation
Three Different Technology Capabilities in One System
• Replicate outcomes of YAG, YSGG, and CO2 with thermal injury
control
Emulation with Heat Control
• Avoid the risks of too much
thermal injury, which can
cause:
• prolonged erythema
• hypopigmentation
CO2 Laser Treatment
Coag Conclusions
• Increasing levels of coag give increasing
amounts of thermal damage
• Level 3 coag is similar in histology to
carbon dioxide fractional histology
Ablation Depth
• 25u-1500u
• Assumption – deeper depths leads to
better results
• Assumption – deeper depths leads to
longer healing times
• What role does MLP play in results and
healing times
ProFractional Therapy–Tunable Ablation
Penetration Depth
• Erbium’s efficient absorption instantly eliminates tissue, creating clean
columns and leaving behind no necrotic debris
• Drills columns as deep as 1500 µ and as superficial as 25 µ
• Select depth appropriate to the indication being treated
Coverage Density
• PF > 1.5 – 60% (250 µ
spot)
• PF-XC > 5.5 or 11% (430
µ spot)
