Alexandrite laser: what it is and how it is used

An alexandrite laser uses a focused wavelength of light to target pigment in selected skin treatments.

It is often described as a 755nm laser. In hair-removal treatment, the device aims energy at pigment in the hair shaft and follicle region. The practitioner selects settings according to factors such as hair colour, hair thickness, treatment area, and skin tone. A laser device is not interchangeable with every other light-based hair-removal system.

Before treatment, a clinician or trained practitioner reviews the area, your medical history, medicines, recent tanning, and previous reactions to light-based procedures. The skin is prepared and protective eyewear is used. The handpiece delivers brief pulses across the planned area. A cooling method may be used to improve comfort and protect the surface of the skin. More than one visit can be needed because hair growth occurs in cycles.

Response varies with the contrast between hair pigment and surrounding skin, as well as hair thickness and the area being treated. Very light, grey, white, or red hair may have little pigment for the laser to target. Recently tanned or irritated skin can require postponement. This technology does not suit every person or every hair type, and it cannot promise complete hair removal.

Alternatives include shaving, waxing, threading, depilatory products, and other professional light-based technologies. Each option differs in convenience, skin effects, and the type of hair it can address. A consultation can help compare these choices with your preferences and medical history.

Ask which device is proposed, why it is suitable for your skin and hair, how the area should be prepared, and what aftercare is needed. Discuss any history of pigment change, scarring, herpes simplex outbreaks near the treatment area, photosensitivity, or medicines that affect the skin. You should also know what normal short-term redness feels like and when to contact the clinic.

Laser treatment should be performed by an appropriately trained practitioner using eye protection and settings selected for you. Redness, warmth, and temporary swelling around hair follicles can occur. Keep the area protected from sun exposure, avoid heat and friction while it is irritated, and follow the aftercare advice you receive. Contact the treating clinic if you develop blistering, increasing pain, or unexpected skin colour change.
