Laser hair reduction on the upper lip, patient wearing protective glasses

Laser hair reduction is one of the most requested treatments at any dermatology clinic, and one of the most misunderstood. Here's an honest walk-through of a typical course.

Why one session is never enough

Hair grows in three phases, and the laser only affects follicles in the active growth phase. At any moment only part of your hair is in that phase, so sessions are spaced out to catch each follicle at the right time. Most areas need six to eight sessions, four to eight weeks apart.

Before your first session

  • Shave the area a day before; don't wax, thread or pluck for four weeks, since the laser needs the root in place.
  • Avoid sun tanning for two weeks. Tanned skin absorbs more energy and is more likely to react.
  • Tell your dermatologist about any medicines, especially antibiotics, acne treatment or hormonal medicines.

What a session feels like

Most people describe a quick snap, like a rubber band, with a warm feeling. Cooling built into the device keeps it comfortable. Small areas such as the upper lip take minutes; full legs take longer.

After the session

Mild redness and small bumps around follicles are normal and settle within hours. Treated hairs shed over the next two weeks, which can look like regrowth at first. Use sunscreen daily and avoid hot showers, saunas and heavy workouts for a day.

How long do results last?

Laser gives long-lasting reduction rather than permanent removal. Most people see far less, finer hair after a full course, and some need an occasional maintenance session. Hormonal conditions such as PCOS can mean more sessions.

The best results come from a dermatologist matching the laser settings to your skin and hair type, which matters especially for Indian skin.
