Laser modality
Fractional LIOB
Pro 1 Pico's fractional LIOB handpieces create controlled micro-zones of optical breakdown for non-ablative remodeling of acne scars, pores, and texture.
LIOB (laser-induced optical breakdown) concentrates picosecond energy into microscopic high-intensity zones, forming controlled non-ablative micro-vacuoles that stimulate a dermal remodeling response while preserving surrounding tissue. Parameters are specified in the device documentation.
What is fractional LIOB?
Fractional LIOB — laser-induced optical breakdown — concentrates picosecond energy into microscopic high-intensity zones, creating controlled non-ablative micro-vacuoles beneath the skin surface. These micro-zones stimulate a remodeling response while leaving surrounding tissue intact, so it provides a fractional remodeling pathway without the downtime of fully ablative resurfacing.
What it is used for
Fractional LIOB is positioned for the structural side of skin quality:
- acne scars and atrophic scars
- post-acne texture and scar-related shadowing
- enlarged pores and uneven texture
- fine lines and photoaging
- non-ablative regenerative rejuvenation
Suitability is assessed per patient by a trained provider.
Where it fits
Fractional LIOB is the “Remodel” engine of the Pro 1 Pico’s four-engine architecture. It pairs naturally with PulseStack™ 750: PulseStack™ 750 provides cumulative dermal stimulation for collagen banking, while LIOB adds stronger fractional remodeling. For more advanced resurfacing, clinics step up to ablative fractional CO₂.
On the Pro 1 Pico platform
LIOB is delivered through optional fractional handpieces on the Pro 1 Pico, alongside picosecond pigment delivery, PulseStack™ 750, and long-pulse 1064 nm vascular YAG. See the Pro 1 Pico product page for specifications, licensing, and regulatory status.
Technical background
Exact pulse parameters, handpiece options, and treatment densities vary by configuration and are listed in the device’s manufacturer documentation. Providers evaluating a specific protocol should request the current specification sheet.

FAQs
What does LIOB stand for?
Laser-induced optical breakdown. Focused picosecond energy creates microscopic zones of optical breakdown beneath the surface, forming controlled micro-vacuoles that stimulate remodeling while leaving surrounding tissue intact.
How is fractional LIOB different from CO₂ resurfacing?
Fractional LIOB is non-ablative — it creates sub-surface micro-zones without vaporizing the surface the way ablative CO₂ does, so it is positioned for remodeling without the downtime of ablative resurfacing. A provider matches the approach to the patient.
How is it different from PulseStack™ 750?
PulseStack™ 750 is rapid-fire pulse-stacking for collagen banking and maintenance. Fractional LIOB is more intensive — focused fractional remodeling for acne scars, pores, and texture.
What is it used for?
Acne scars, post-acne texture, enlarged pores, uneven texture, fine lines, and non-ablative rejuvenation — provider-selected per patient.
