Candela GentleLASE vs. GentleMAX vs. GentleYAG: Which Treatments Use Cryogen?

Candela’s flagship platforms—GentleLASE, GentleYAG, and GentleMAX / GentleMAX Pro—are widely used for hair removal and dermatologic indications. A key element across these systems is the Dynamic Cooling Device (DCD), which sprays a brief burst of cryogen onto the skin to protect the epidermis and improve comfort immediately before the laser pulse.

Why Cryogen Cooling Matters

• Epidermal protection: Rapid surface cooling reduces the risk of thermal injury.
• Higher efficacy settings: Cooling enables the safe use of effective fluences and pulse widths.
• Patient comfort: Less heat sensation and post-treatment redness.
• Consistency: Stable, repeatable spray patterns support predictable outcomes.

GentleLASE (755 nm Alexandrite)

Optimized for lighter skin types with fine to medium hair. Also used for pigmented lesions and photodamaged skin.

• Primary uses: Hair removal, benign pigmented lesions.
• Cryogen role: DCD cryogen protects the epidermis and allows efficient hair removal settings.

GentleYAG (1064 nm Nd:YAG)

Designed for deeper penetration and safer use on darker skin phototypes; also effective for vascular indications.

• Primary uses: Hair removal on all skin types, leg veins, vascular lesions.
• Cryogen role: DCD cryogen improves tolerability and safety with deeper-penetrating Nd:YAG energy.

GentleMAX / GentleMAX Pro (755 nm + 1064 nm)

A versatile dual-wavelength platform combining Alexandrite and Nd:YAG to address a broad range of hair and skin concerns.

• Primary uses: Hair removal for all skin types, pigmented/vascular lesions, skin rejuvenation.
• Cryogen role: DCD cryogen maintains patient comfort and epidermal safety across both wavelengths.

Best Practices for Cryogen Use

• Use high-purity canisters to prevent nozzle clogging and ensure even spray.
• Store canisters upright in a cool, dry place away from heat sources.
• Inspect seals and perform test sprays before treatment sessions.
• Maintain the DCD module and replace canisters at the first signs of weak or inconsistent spray.

Conclusion

Whether you use GentleLASE, GentleYAG, or GentleMAX, cryogen spray cooling is central to safer, more comfortable, and more effective treatments. A reliable supply of compatible, high-purity cryogen keeps workflows smooth, enhances patient experience, and supports optimal clinical results.
