Hi,
Firstly, one should recognize that different laser treatments are associated with different risk and severity of PIH so it is important that you discuss this with your doctor prior to treatment.
PIH after laser treatment may be reduced but not completely avoided. What can be done to reduce the occurrence and severity of post-laser PIH include:
1. Pre-treating the skin with skin lightening creams several weeks before the laser treatment and continuing treatment after laser treatment.
2. Avoiding laser treatment if you have a tanned skin as a tanned skin is more prone to developing PIH. Start treatment only after your tan has completely subsided.
3. Strict sun avoidance and protection after laser treatment. This is because UV radiation stimulates the active melanocytes after laser treatment and worsens the PIH.
4. Avoid additional irritation to the skin post-laser e.g. use of harsh soaps and scrubs.
Hope this helps!
