🧪 Dermatologist's Tip #4: Beware of Pigmentation from Topical Applications! 🧪
Sometimes, the very products we use can cause discoloration! Certain insect repellents, perfumes, or even some medications applied topically can cause hyperpigmentation, especially when exposed to the sun (a phenomenon called photo-contact dermatitis). Always patch test new topical products and be mindful of sun exposure when using ingredients known to cause photosensitivity. If you notice localized darkening after applying something new, discontinue use and consult your dermatologist.
