INTENSE PULSED LIGHT (IPL) is a broad spectrum light that can be used to treat brown spots and redness. Oahu Dermatology uses the ICON platform. IPL targets melanin resulting in reduction of pigmentation found in freckles, lentigines ( sunspots) and melasma or hemoglobin in blood cells to reduce redness. The treatment takes 10 - 30 minutes depending on how much skin is being treated. Usually, 2 - 3 sessions are required for freckles/lentigines and 4 - 5 sessions for melasma and number of sessions will vary for redness based on size and location. There is minimal downtime with transient pinking and “coffee grounds” appearance if treating brown spots. We advise to avoid sun exposure one week before and after treatment. If using a retinoid as part of your skincare regimen, hold this for 3 - 5 days before your procedure and 7 days after.
