Diode 1540 nm laser for acne: who it helps

How the 1540 nm laser targets oil glands to reduce active acne, who is a good candidate, and what sessions look like.

Short answerThe 1540 nm laser targets the oil (sebaceous) glands deep in the skin, reducing oil production and the inflammation behind breakouts. It helps people whose acne persists despite creams or tablets, or who want to reduce long-term reliance on medication. A course is usually 3 – 5 sessions.

How it works

Acne starts with excess oil, blocked pores, bacteria and inflammation. The 1540 nm wavelength is absorbed by water in the dermis around the oil glands, gently heating and shrinking their activity, while the surface is protected by cooling.

Good candidates

  • Persistent, moderate inflammatory acne
  • Very oily skin with frequent breakouts
  • People who can't take, or want to reduce, oral acne medicines
  • Adult acne, including hormonal patterns, alongside medical therapy

What to expect

Sessions take 20 – 30 minutes, with warmth and mild redness afterwards. Most people notice less oiliness and fewer new pimples over the course. We combine it with the right skincare, peels and, when needed, medicines, then move to scar treatment once acne is under control.
