Cervello Laser Hair Removal

Regenevéda is the first clinic in Chicago to use the Cervello multi-wavelength laser system for hair removal, combining 755 nm Alexandrite, 808 nm Diode, and 1064 nm Nd:YAG wavelengths in a single device to achieve safe and effective permanent hair reduction across all Fitzpatrick skin types. The Alexandrite wavelength targets lighter melanin most efficiently, the Diode offers intermediate skin penetration for a broad range of skin tones, and the YAG wavelength provides the deepest penetration suitable for darker or tanned skin. Multiple sessions are required to capture follicles across growth cycle phases.

Cervello Laser Hair Removal at Regenevéda deploys a tri-wavelength diode laser system — incorporating 755 nm Alexandrite, 808 nm Diode, and 1064 nm Neodymium:YAG (Nd:YAG) energy in a single handpiece — that allows the treating clinician to select the optimal wavelength or combination for the patient's Fitzpatrick skin type, hair colour, and treatment area. Regenevéda is documented as the first clinic in Chicago to have acquired the Cervello system, giving the practice a differentiated technology positioning in the Chicago laser aesthetics market. Laser hair removal operates on the principle of selective photothermolysis: the laser energy is selectively absorbed by the melanin chromophore within the hair shaft and matrix cells, converting to heat that damages the follicle's stem cell reservoir (the bulge region) and dermal papilla while sparing the surrounding skin if the wavelength, pulse duration (fluence-on-skin time), and cooling parameters are correctly calibrated for the patient's skin tone and hair type. The three wavelengths serve distinct roles: 755 nm Alexandrite is most efficiently absorbed by eumelanin (the dominant pigment in dark hair) with relatively superficial penetration, making it optimal for lighter Fitzpatrick skin types (I–III) with coarse dark hair; 808 nm Diode offers a balance of melanin absorption and tissue penetration depth suitable for skin types II–IV and a wide range of hair textures; 1064 nm Nd:YAG is the least absorbed by melanin, requiring higher fluences, but penetrates deepest (up to 5–7 mm) and is the safest wavelength for darker Fitzpatrick skin types (V–VI) where competing epidermal melanin absorption creates a burn risk at shorter wavelengths. Regenevéda's Cervello system allows session-by-session or simultaneous combination of wavelengths, providing flexibility for patients of mixed heritage or variable skin tone. A typical hair removal course spans six to eight sessions at four to eight week intervals timed to the hair growth cycle phases; maintenance sessions once or twice per year may be needed after the initial series. The clinic's medical team supervises all laser procedures at 8 S Michigan Ave, Suite 812, Chicago.
