How does light-based hair reduction work?
Laser hair reduction uses light energy to target pigment in hair follicles. It can reduce unwanted hair, but the response varies with hair colour, skin tone, the treatment area and other factors.
Intense pulsed light (IPL) and lasers are different technologies. Ask which method is being recommended and why it is appropriate for your skin and hair.
Planning a suitable treatment
The consultation should cover your skin and hair type, recent tanning, medicines and previous skin treatments. Tell your dermatologist about any history of pigment changes or scarring.
Your treatment plan may include a test area, preparation advice and a discussion of the likely response. Light-based treatment does not work equally well for every hair colour or skin type.
Sessions and maintenance
Hair grows in cycles, so repeated sessions are commonly needed. The number and spacing of treatments should be planned around your response rather than a fixed promise.
Some hair may regrow, and maintenance treatment may be needed. Discuss what reduction is realistic for your particular treatment area.
Comfort, risks and aftercare
Temporary redness, swelling or discomfort can occur. Other risks include burns, changes in skin colour and, less commonly, scarring. Treatment is not guaranteed to be painless or free of side effects.
Follow your dermatologist’s instructions on sun protection, skin care and activities after each session. Report unexpected or persistent symptoms to the treating team.
YOUR QUESTIONS
A little more clarity.
Will every hair be permanently removed?
Complete permanent removal cannot be promised. Many people achieve hair reduction, but regrowth and maintenance treatment are possible.
Is treatment painless?
Discomfort varies. Ask about measures to improve comfort and the risks for your skin type.
How many sessions will I need?
The plan depends on the area, hair growth cycle and response. Your dermatologist can discuss an expected course after assessment.
