@drheejink: Top 5 skincare horror stories as a dermatologist! 😱 1. Tanning beds → major UV damage, accelerates aging + increases skin cancer risk 2. A “pimple” that won’t heal → could be something more serious, like skin cancer 3. “Sunscreen is toxic” → skipping SPF leads to preventable sun damage and pigmentation, and increases the risk of skin cancer 4. Blue-black discoloration from hydroquinone misuse → Ochronosis (blue-black discoloration) is a side effect of hydroquinone, especially if misused for a long time without taking a break. It is very difficult to treat! Please use hydroquinone under the guidance of a dermatologist. 5. Walking barefoot in public pools/locker rooms → increased risk of getting warts or athlete’s foot #drheejink #dermatologist
