Diolaze XL Diode Laser Hair Removal

Diolaze XL at DiVine Clinic is a diode laser hair removal system manufactured by InMode that delivers permanent hair reduction through selective photothermolysis — targeting melanin in hair follicles with a high-power 810 nm diode laser. The concentrated laser energy is absorbed by the melanin in the follicle and shaft, converting to heat that destroys the follicle's germinal cells while the surrounding skin remains unaffected due to its lower melanin concentration. MUDr. Petra Moravcová performs an initial consultation to assess suitability and skin/hair type; the laser sessions themselves are performed by trained clinical staff. Treatment areas include the face, neck, underarms, forearms, arms, chest, abdomen, back, groin, legs, and intimate zone. 2–3 sessions are standard for most patients; blonde, grey, or very fine hair requires more sessions and responds more slowly due to lower melanin content. Patients should shave the treatment area 2–3 days before each session.

Diolaze XL is a high-power diode laser hair removal platform manufactured by InMode, featuring a 810 nm diode laser with built-in contact cooling in the applicator head. It is among the high-efficacy, high-speed systems used in clinical aesthetic medicine, capable of treating larger body areas in a short session due to its large spot size and high fluence. **Selective photothermolysis — the mechanism:** The Diolaze XL emits 810 nm near-infrared laser energy, which is within the absorption peak of eumelanin (the dark pigment in hair). When the laser pulse is delivered to skin containing a hair follicle, the melanin in the follicle and hair shaft preferentially absorbs the light energy and converts it to heat. The follicle temperature rises rapidly to the thermal damage threshold (70–80°C), destroying the germinal cells of the hair matrix and the follicle bulge (stem cell niche) that are responsible for hair regrowth. Because the surrounding skin contains far less melanin than the follicle, it absorbs far less energy — especially with the Diolaze XL's contact cooling system, which simultaneously cools the epidermis during the pulse. **Why multiple sessions are needed:** Hair follicles cycle through three phases — anagen (active growth, 2–7 years), catagen (transition, 2–3 weeks), and telogen (resting, 3 months). Laser hair removal is only effective on follicles in the anagen phase, when the follicle is fully formed, connected to the papilla, and richly melanin-pigmented. At any point in time, only 15–20% of follicles on a given body area are in anagen, so each session treats only those follicles while leaving the catagen and telogen follicles unaffected. Subsequent sessions 4–8 weeks apart (when those resting follicles have cycled back into anagen) progressively reduce the total follicle count. After 2–3 sessions (for dark, coarse hair), the majority of follicles have been targeted at least once. Results are permanent for destroyed follicles, though dormant or vellus follicles can activate later in life, particularly with hormonal changes. **Hair type considerations:** The laser targets melanin, so the technique works best on dark, coarse hair against lighter skin. Blonde, red, grey, and white hair contains phaeomelanin or no melanin — these are poorly targeted and may require significantly more sessions (5–8+) or may not achieve the same level of permanent reduction. MUDr. Moravcová discusses realistic expectations for lighter hair at the initial consultation. **Areas and pricing at DiVine Clinic:** The clinic offers Diolaze XL treatment for all body areas including face, neck, underarms, forearms, arms, chest, abdomen, back, lower abdomen, areola, groin, legs, and intimate zone. Upper lip and chin are offered as a full course from 5,000 Kč due to the hormonal nature of facial hair. **Preparation and aftercare:** Shave the target area 2–3 days before each session (not immediately before — some stubble helps target the follicle). Avoid waxing, threading, or epilating for 4–6 weeks before treatment as these remove the follicle physically. Avoid tanning and self-tan for 4 weeks pre-session. Post-session: avoid sun exposure, saunas, and hot showers for 48 hours; redness and warmth at the treatment site resolve within hours. **Contraindications:** Very light or grey hair (low efficacy); active tan or darker skin types without appropriate settings adjustment; photosensitising medications; active infection or skin condition in the treatment zone; pregnancy (caution, not absolute contraindication in all guidelines, but typically deferred).
