Alexandrite laser hair removal
Alexandrite laser hair removal uses laser light with a wavelength of 755 nm to penetrate the epidermis. The melanin in the hair follicles absorbs the energy, generating high temperatures that destroy the growth structure of the follicles, thereby reducing hair growth.
Hair removal cannot be completed in a single session as hair growth occurs in three phases: the anagen (growth) phase, the catagen (regression) phase, and the telogen (resting) phase. Melanin is only present in the hair follicles during the anagen phase, so the laser can only target follicles that are in this active growth phase.
Precautions before treatment:
- Stop using irritants such as retinoids or fruit acids on the treatment area three days prior.
- Avoid shaving the area three days before the treatment to prevent any open wounds.
Post-treatment care:
- Immediately after the treatment, the hair will fall out, and temporary warmth and redness may appear on the skin. This usually subsides gradually after applying cold packs or cool air for 20 minutes.
- Avoid using irritants (such as retinoids or fruit acids) and exfoliating products for three days after the treatment. Also, avoid exposure to high temperatures (such as saunas, heaters, ovens, or hot springs).
