Energy-based devices — fractional CO₂, erbium, picosecond, alexandrite, Nd:YAG, KTP, PDL, IPL. The chromophore framework and what each actually does.
Exosomes are applied after laser to speed recovery, but no product is FDA-approved and the clinical evidence is early-stage. Here is what patients should actually know.
Acne scar treatment in darker skin (Fitzpatrick IV-VI) requires modalities that minimize PIH. RF microneedling and subcision are safest; fractional CO2 carries higher…
CO2 lasers penetrate deeper with more collagen contraction — stronger results, longer recovery, higher PIH risk. Er:YAG ablates precisely with less heat — faster…
Halo, Moxi, and Fraxel are fractional lasers from Sciton and Solta Medical. Here is how their wavelengths, depths, downtime, and clinical evidence compare — and which…
IPL and BBL HEROic both use broadband light for pigment and redness, but differ in energy delivery, speed, and FDA clearance. How they compare, who is a candidate, and…
Laser resurfacing in Black skin requires matching wavelength and energy to melanin-rich tissue. Non-ablative 1540/1550 nm and 1064 nm Nd:YAG are safest; ablative CO2…
Lasers can worsen melasma in darker skin via rebound hyperpigmentation and melanocyte activation. Low-fluence QS Nd:YAG toning helps but carries risks. Evidence on safe…
Ultherapy is the only device FDA-cleared to lift. Thermage tightens. RF microneedling remodels texture. Lasers smooth surface. None repositions tissue like a surgical…
Vbeam (595 nm PDL) and Excel V (532/1064 nm KTP/Nd:YAG) are the dominant vascular laser platforms. How they compare on mechanism, evidence, comfort, purpura risk, and…
PicoSure (755 nm) and PicoWay (532/1064/785 nm) are the dominant picosecond laser platforms. The choice depends on ink color, skin type, and whether the target is…
