Pinpoint Coagulation™
Pigmented Lesions
Treatment
Pinpoint Coagulation™ is LINLINE’s selective method for treating melanin-based pigmented lesions on the MULTILINE™ base unit. Using nanosecond pulse-trains at pigment-friendly wavelengths (e.g., 694nm Ruby, 755nm Alexandrite), the system coagulates melanin-dense cells while sparing normally pigmented skin — a strategy designed for efficacy on epidermal and dermal pigment with minimal risk of scarring or PIH.
✽ Advantages
Why Pinpoint
Coagulation™ is different
Targets melanin-dense cells
Short (ns) pulses raise melanin’s absorption non-linearly, converting laser energy into heat + acoustic waves right inside melanin granules. Surrounding, normally pigmented tissue stays below injury thresholds.
Pulse-train
A sequence of nanosecond pulses is delivered with controlled timing. Between pulses, heat conducts away from pigment into adjacent tissue at different rates; where pigment is absent, temperature normalizes faster. The next pulse therefore re-heats only the melanin-dense points, producing “pinpoint” coagulation instead of broad heating.
For deep and stubborn lesions
Because energy localizes inside pigment granules, the method can address deeper or denser foci without removing healthy tissue, reducing the classic risks of thermal injury, scarring, and post-procedure hyperpigmentation.
✽ Applications
What it treats
Acquired hypermelanoses
Melasma/chloasma, solar lentigines, post-inflammatory and post-traumatic hyperpigmentation.
Hereditary/constitutional pigmentations
Ephelides (freckles), congenital hypermelanoses (e.g., café-au-lait).
Depth spectrum
Epidermal and dermal pigment (protocols and intervals differ by depth).
