Photomechanical remodeling for scars with a pigmentation component
PicoLaser is particularly valuable for acne scars that also carry a pigmentation component (post-inflammatory hyperpigmentation overlying a depressed scar). Its photomechanical effect remodels collagen within the scar while simultaneously clearing the associated discoloration — addressing both dimensions of the scar in one treatment.
How it works
In addition to its melanin-shattering effect, PicoLaser's pressure wave creates micro-cavitation bubbles within the dermis that mechanically disrupt the dense, disorganized collagen architecture of scar tissue without ablating the surface. This 'laser-induced optical breakdown' triggers a collagen remodeling response that gradually reorganizes the scar matrix. Fractional PicoLaser modes (LIOB — laser-induced optical breakdown) can be targeted to specific scar depths, allowing precise collagen stimulation at the level of the scar floor. The simultaneous clearance of overlying PIH means that scars that appear dark and textured can see improvement in both dimensions simultaneously.
What to expect
Topical numbing is applied. The treatment feels similar to standard PicoLaser — a snapping sensation with mild warmth. Treatment time varies by the number of scars addressed. Redness and mild swelling follow.
Downtime and aftercare
Minimal for standard PicoLaser. Fractional modes may cause 2–3 days of mild texture changes and redness.
Results
Best for scars with concurrent pigmentation or mild textural irregularity. Typically combined with RF Microneedling or TCA CROSS for comprehensive scar management.
