Is laser treatment effective for prolonged redness and PIH due to surgical scars?Aesthetic Medicine
Hi. I have prolonged erythema and post inflammatory hyperpigmentation from surgical scars. This has lasted for more than 1.5 years. Is laser treatment effective for surgical scar marks? If yes, how can I find a doctor in Singapore who is proficient and regularly treating the above condition? Thank you.
Thank you for your question. Laser is a good method of treating prolonged redness and post inflammatory hyperpigmentation (PIH) from surgical scars.
The redness and erythema can treated with a pulsed dye laser while the PIH can be treated with gentle laser toning.
Laser treatment can be combined with topical agents such as triluma/ hydroquinone/ retinoid for the best result.
Speak to a dermatologist/ aesthetic physician/ plastic surgeon to find out more. Hope this helps!

Prolonged redness/erythema and Post-inflammatory Hyperpigmentation (PIH) will require different types of Lasers to precisely treat these conditions.
PIH will require Picosecond Nd:YAG/Alexandrite lasers or Q-switched Nd:YAG lasers. Picosecond Lasers are proven to be more effective for stubborn PIH that cannot be removed with Q-switched lasers. (https://www.ncbi.nlm.nih.gov/pubmed/29200769)
Prolonged erythema can be removed with Pulse Dye Lasers or Copper bromide lasers.
The first step to finding a doctor who is proficient in treating the above conditions is to find a clinic that offers the above Lasers.
Next, ask the doctor for before/after photos of the cases that he has treated using these lasers.
Lastly, look for a doctor who can give you a comprehensive treatment plan as these laser treatments usually require several sessions with good post-laser aftercare to ensure optimal results.
Hope that this helps!
