What is laser hair removal done with?

The device sends pulses of light into the skin. Pigment in the hair absorbs part of this energy, producing heat around the follicle and reducing its ability to grow hair. Because hair cycles through growth phases, treatment is usually planned as a series of appointments rather than one session.

Alexandrite, diode and Nd:YAG systems use different wavelengths. A clinician selects the approach based on skin tone, hair colour, hair thickness and the body area, with settings adjusted to protect the surrounding skin.

Tell the clinic about recent tanning, medicines that increase light sensitivity, active skin irritation and any history of unusual scarring. Avoid plucking or waxing the target hair when instructed, because the follicle needs to be present for the laser to target it. Shaving may be recommended before the appointment.

After treatment, protect the area from heat and sun as advised. Temporary redness or follicle-centred swelling can occur; use only the soothing products recommended for your skin.

Contact the provider for blistering, severe pain, marked swelling, crusting or skin colour changes that are spreading or worsening. Prompt assessment can help distinguish expected short-lived redness from a treatment reaction.

Ask which wavelength is suitable for your skin and hair, how your skin will be cooled, what preparation is required, and how many growth cycles may need treatment. Confirm sun precautions and the signs that require a review.
