What RePat Treats
Lentigo (Age Spots)
The specialty — clears dark, well-defined spots in 1–3 sessions.
Stubborn Pigmentation
Effective for melasma, freckles, and uneven pigmentation that resist other lasers.
Solar Lentigines
Sun-induced spots on face, hands, décolletage.
Picosecond Pulse
Shatters pigment without heating surrounding tissue — gentler than Q-switched lasers.
Why Pico-Second?
Traditional Q-switched lasers deliver pulses in nanoseconds. Pico-second lasers (10⁻¹² seconds)
deliver energy 1,000× faster, which means:
- Photoacoustic effect — pigment is shattered, not just heated
- Less thermal damage to surrounding skin
- Faster healing compared to traditional pigment lasers
- Better for darker skin types — lower risk of post-inflammatory hyperpigmentation
