Laser Hair Removal

Esthesia Clinic offers professional diode laser hair removal at 810nm wavelength with integrated cooling, covering all body areas from the upper lip to full legs. The diode laser targets melanin in hair follicles, delivering a thermal pulse that damages the follicle's stem cells in the growth (anagen) phase without affecting surrounding skin. Integrated contact cooling protects the skin surface throughout, making the treatment suitable for sensitive areas and most skin types. A minimum of 6–8 sessions spaced 4–8 weeks apart is required to treat all follicles across their different growth cycles. Sessions are performed by trained aesthetic therapists with medical oversight.

Laser hair removal is the gold-standard method for permanent hair reduction — the only regulatory-approved category of hair removal that offers long-term results by targeting and thermally destroying hair follicles at the root. Esthesia Clinic uses a professional-grade 810nm diode laser, the optimal wavelength for targeting melanin (hair pigment) across a wide range of skin and hair colour combinations. **How it works — the physics:** The 810nm diode laser emits a beam of coherent light at a wavelength preferentially absorbed by melanin in the hair shaft and follicular bulb. When the laser pulse hits the hair, the melanin absorbs the energy and converts it to heat. If the heat is sufficient (typically 60–70°C at the follicle root) and is sustained long enough (pulse width matched to the follicle diameter), the follicular stem cells in the bulge region are thermally destroyed, preventing future hair growth from that follicle permanently. The key technical parameters — pulse width, fluence (energy density, J/cm²), spot size, and repetition rate — are calibrated to the patient's skin type and hair characteristics at each session. **Integrated cooling:** The diode laser handpiece includes contact-cooling (cooled sapphire tip) that chills the skin surface to 4–10°C during the pulse, protecting the epidermis and dermis from thermal damage while allowing sufficient energy delivery to reach the follicle. This combination of selective photothermolysis + contact cooling makes the treatment comfortable and safe on sensitive body areas including the face, underarms, and bikini line. **Hair growth cycle — why multiple sessions are needed:** Hair follicles cycle through three phases: anagen (active growth — follicle attached to papilla, melanin-rich, most sensitive to laser), catagen (transition), and telogen (resting — follicle detached from papilla, laser cannot destroy it). At any given time, approximately 20–30% of follicles are in anagen phase. Each laser session treats the anagen-phase follicles present that day. After 4–8 weeks, previously catagen/telogen follicles have re-entered anagen and become treatable. A minimum of 6–8 sessions is required to treat the full follicle population across multiple cycles; hormonal areas (face, bikini) typically require 8–12 sessions due to continued androgen-driven new hair growth. **Treatment areas and prices:** - Upper lip: 600 Kč | Chin: 700 Kč | Full face: 1,800 Kč - Underarms: 1,500 Kč | Arms (lower): 2,000 Kč | Arms (full): 3,000 Kč - Bikini (line): 1,500 Kč | Bikini (full): 2,500 Kč | Brazilian: 2,800 Kč - Lower legs (women): 4,000 Kč | Full legs (women): 7,500 Kč - Chest (men): 3,500 Kč | Back (men): 5,000 Kč - 5-session packages: approximately 50% discount on per-session price **Results:** After a full 6–8 session course, most patients achieve 80–90% permanent hair reduction. The remaining fine vellus hairs and occasional regrowing follicles are managed with annual maintenance sessions. **Skin type range:** The 810nm diode laser is effective and safe across Fitzpatrick types I–V. Fitzpatrick VI (very dark skin) requires specialised long-pulse Nd:YAG settings to minimise epidermal melanin absorption — this should be discussed at consultation. **Contraindications:** Active tanning or recent sun exposure (minimum 4 weeks sun-free before sessions), pregnancy, isotretinoin use within 6 months, active herpes simplex (for facial treatments), pacemaker/metal implants in the treatment zone.
