If you’re already doing everything possible to avoid pigmentations but still suffer from them, or if you notice yourself getting very reactive to exposure to the sun or light, ask your dermatologist for a photo-patch test.
A photo-patch test is very similar to a patch test but is specific to common substances that are known to produce pigment reactions in skin.
Learning what substances you’re sensitive to can help you prevent:
- Photosensitivity: severe redness, darkening or other reactions with exposure to the sun and even light sources like indoor lights and computer/TV screens.
- Hyperpigmentations: dark spots (like melasma or scars after insect bites, acne or a rash) or more generalized skin darkening.
