In-House Procedures


How does freezing work?

This method of treatment has been used for many years. Although several substances can be used, evaporation of the gas mixture is the most common, which produces a controlled burn. This will destroy the top layer of the skin and is generally safe and well tolerated.

What problems may occur?

  • Pain
    • Most people will experience some discomfort, which usually responds to paracetamol if required.
  • Blister formation
    • Occasionally a clear water or blood blister may form especially in people with sensitive or fair skin. If this occurs, simply puncture the roof of the blister with a clean needle and let out any fluid. Repeat this until it no longer refills.
  • Infection
    • Increasing pain or redness occurring a few days after treatment may indicate infection. If this occurs, you will need a prescription for either antibiotic cream or oral tablets.
  • Scarring
    • There is likely to be some redness and a small scar after this procedure, which will settle over time. Generally, the cosmetic results after this procedure is excellent.

Please consult Dr Mok if you need further information on this form of treatment.

What should I expect after treatment?

  • The treated area will behave like a small burn and you may get some soreness and stinging at the time of treatment.
  • After treatment, redness will normally occur and will gradually settle over a week or so.
  • Swelling is common and can be severe around the eye. This normally settles after a few days.
  • Many wounds weep for a few days; during this time a dressing can be applied to absorb the fluid. Your doctor will discuss this with you. If a scab or crust forms, apply Vaseline or an antibiotic ointment if you doctor has prescribed one and simply let it fall off in due course. Using a greasy moisturizer like Vaseline twice daily will help the skin heel faster.
  • The wound should be washed with soap and water 2-3x daily and kept as clean as possible.
