Diolaze XL

One of the most powerful laser hair removal systems available — with a large spot size and built-in cooling for fast, comfortable, and permanent hair reduction on all skin types, including darker tones. Diolaze XL combines high peak power with intelligent skin cooling for superior results with fewer sessions.

Areas Treated

Diolaze XL treats all areas of unwanted hair growth across the face and body, with its large spot size making it particularly efficient for extensive body areas.

Full Body

Legs, arms, back, chest, and abdomen — the large 3cm² spot size enables fast treatment of extensive body areas in a single session.

Underarms

Permanent hair reduction of the axillary region — typically 4–6 sessions for near-complete clearance.

Bikini / Brazilian

Full bikini and Brazilian hair removal including the inguinal and pubic regions.

Face

Upper lip, chin, jawline, sideburns, and full facial hair removal — using reduced spot size and energy for facial anatomy.

Neck & Nape

Posterior neck hair and nape hairline shaping for both men and women.

Ingrown Hairs

Permanent reduction of hair follicles causing recurrent ingrown hairs — particularly effective for pseudofolliculitis barbae on darker skin.

Treatment Parameters

Diolaze XL uses an 810nm diode laser wavelength optimally absorbed by melanin in the hair follicle. Treatment parameters are adjusted based on skin type (Fitzpatrick), hair colour, and treatment area. Built-in cooling allows for higher fluences with improved comfort.

Skin Type	Fluence (J/cm²)	Pulse Width	Cooling
FST I–II	30–50	10–20ms	Standard
FST III	25–40	20–30ms	Standard
FST IV	18–30	30–50ms	High
FST V	14–22	50–80ms	High
FST VI	10–16	80–100ms	Maximum

Clinical Notes

Shave the treatment area 24 hours before the session. No topical anaesthetic is typically required due to integrated cooling. Avoid sun exposure for 2–4 weeks pre- and post-treatment. Darker skin types require longer pulse widths and lower fluences — test patch mandatory. 4–6 sessions spaced 4–8 weeks apart recommended for most areas, with maintenance sessions as required.

FAQs

Common questions about Diolaze XL. Contact STERN Laser for clinical guidance specific to your practice.

Most patients achieve significant permanent hair reduction in 4–6 sessions, spaced 4–8 weeks apart. Areas with hormonal influence (face, bikini) may require more sessions. Hair colour, coarseness, and skin type affect the number of sessions required. Annual maintenance treatments are recommended for any residual regrowth.

Yes — Diolaze XL is suitable for Fitzpatrick V and VI skin types when using appropriate pulse widths (50–100ms) and conservative fluences with maximum cooling. A patch test is mandatory before treatment on darker skin. The longer pulse widths allow the heat to dissipate from the epidermis while still targeting the follicle.

Diolaze XL is most effective on dark (brown to black) hair. It is less effective on blonde, red, grey, or white hair because these hair types contain less melanin to absorb the laser energy. Very fine vellus hair is also generally not treatable with any diode laser.

There is no downtime after Diolaze XL treatment. Patients may experience mild redness and follicular swelling for a few hours post-treatment, which resolves spontaneously. Avoid heat exposure, hot baths, and direct sunlight for 24–48 hours.
