Candela GentleLase Pro — The Alexandrite Standard
The Candela GentleLase Pro is a single-wavelength 755nm Alexandrite laser dedicated to high-speed hair removal and pigmented lesion treatment on Fitzpatrick skin types I-III. While the dual-wavelength GentleMax Pro has largely superseded it for multi-ethnic clinics, the GentleLase Pro remains an incredibly reliable, high-ROI workhorse for practices primarily serving lighter skin demographics. Pre-owned units represent one of the best values in aesthetics, trading between $15,000-$35,000.

GentleLase Pro vs GentleMax Pro
| Feature | GentleLase Pro | GentleMax Pro | |---|---|---| | Wavelengths | 755nm Alex | 755nm Alex + 1064nm Nd:YAG | | Skin Types | I - III (Fair to Medium) | I - VI (All skin types) | | Used Price | $15K-$35K | $25K-$65K | | Best For | Startups in non-diverse markets | Clinics needing universal coverage |
The Upgrade Path: Many Candela GentleLase Pro systems are "upgradeable" to a GentleMax Pro. Candela originally sold the GLP with the physical space to add the 1064nm Nd:YAG module later. However, adding the module via Candela OEM often costs as much as buying a used GentleMax Pro outright.
Frequently Asked Questions
Can the GentleLase Pro treat dark skin?
No. The 755nm Alexandrite wavelength is highly absorbed by melanin. Using it on Fitzpatrick skin types IV-VI (darker skin) carries a severe risk of burns, blistering, and permanent hypopigmentation. Dark skin requires a 1064nm Nd:YAG laser (like the GentleYAG Pro or GentleMax Pro).
How long does a GentleLase Pro handpiece last?
Like the GentleMax Pro, the 755nm handpiece and fiber optic delivery system typically require a rebuild or replacement every 3 to 5 million pulses. Budget $8,000-$12,000 for this maintenance via a third-party ISO.
