What should you know about q switched alexandrite laser?

Alexandrite energy is absorbed by particular pigment colours, so the clinician chooses it only when the target is likely to respond. It may be considered for selected pigmented lesions or tattoo inks, but wavelength choice depends on ink colour, depth, skin tone, and the diagnosis. Treated skin can become red, swollen, crusted, or temporarily lighter or darker. Laser cannot make an uncertain mole safe to treat without assessment.

Discuss recent tanning, active dermatitis, medicines, cold sores, previous laser reactions, and any tendency to form thick scars. Follow the clinic's instructions about cleansing, dressings, and ointment. Do not pick crusts or rub the area, and protect it from sunlight while it heals. Delay irritating skincare, shaving across the site, or friction until the surface is comfortable and intact.

Ask the treating clinic for advice if pain or swelling worsens, redness expands, or the skin develops spreading blisters, pus, fever, or increasing warmth. Promptly report a raised scar or pronounced colour change. Emergency help is appropriate for severe facial swelling, wheezing, or trouble breathing after treatment or a related product.

Ask what target is being treated, why 755 nm is suitable, whether a test spot is recommended, how pigment changes will be monitored, and whether another laser or non-laser option would better fit your skin.
