Laser treatment overview and risks

Laser technology plays an important role in dermatology for treating unwanted hair, redness, visible veins, brown marks and tattoos. Each laser is designed to target a specific structure within the skin, such as pigment or blood vessels, while minimising damage to surrounding tissue.

Types of laser treatments

Common laser treatments offered include:

The choice of laser and treatment plan depends on the condition being treated, skin type and individual goals.

General treatment process

Before laser therapy, a consultation is carried out to assess your skin, review medical history and confirm suitability. Patch testing may be recommended for some treatments. During each session, you will wear protective eyewear while controlled pulses of laser energy are delivered to the treatment area.

Treatment times vary from a few minutes for small areas to longer sessions for larger or multiple sites.

Common side effects

Most laser procedures have a predictable and manageable recovery. Common short term effects include:

  • Redness and mild swelling
  • Temporary darkening or frosting of pigmented lesions
  • Warmth or mild discomfort similar to sunburn

These effects usually settle within hours to a few days, depending on the treatment type and intensity.

Potential risks

Although complications are uncommon when lasers are used appropriately, possible risks include:

  • Blistering or crusting of the treated area
  • Infection at the treatment site
  • Changes in pigmentation, either lightening or darkening
  • Scarring, especially if aftercare instructions are not followed
  • Incomplete response or need for additional sessions

Careful selection of settings, appropriate skin preparation and good aftercare all help to minimise these risks.

Aftercare and sun protection

After laser treatment, gentle skin care and strict sun protection are essential. Treated areas are often more sensitive to sunlight in the short term and exposure can increase the risk of pigment change.

You may be advised to use high factor broad spectrum sunscreen and to follow specific guidance on moisturisers, make up use and activity restrictions until the skin has settled.
