What is Post Inflammatory Hyperpigmentation (PIH)?
PIH is also called Pigmented Scars. Any time your skin gets injured or becomes red (sun, heat, acne, laser treatments that peel off the skin, or misuse/overuse of products such as Retin A, Hydroquinone, home chemical peels, and bleaching creams), the skin heals by inflammation.
Inflammation causes melanocyte (spot producing cells) to send melanin or pigment to the skin surface to protect it. This leaves spots such as acne spots, or blotchiness that looks like a patch throughout areas of the face. Sometimes PIH can mimic melasma. Many people who attempt to treat melasma after various aggressive peeling lasers and chemical peels may actually have PIH resting on top of their melasma. Therefore, both exist together. The good news is both can be and are treated the same way.
PIH is not as deep as melasma and can therefore respond to Spectral Q-switch laser faster than melasma.
We usually recommend preparing the skin with bleaching cream for 6 weeks (for ethnic skin) prior to the treatment, which will minimize the development of PIH. In any case, we recommend completing a minimum of 12 Spectral lasers combined with a light superficial Fraxel at the end (Using the new Fraxel Dual Laser). We also implement cooling measures before, during, and after treatment to prevent inflammation.
Sun greatly increase formation of PIH. Avoid sun exposure. You will need “Suppression Therapy”: Daily application of Cosmeceuticals that suppress melanocyte from being activated by heat and sun.
