That “Pimple” That Won’t Heal? Do This Test Today | Dr. William Li

Описание: Worried about a new spot on your skin? A rough patch, a “pimple” that won’t heal, a mole that looks different, or an age spot that seems to be spreading can be more than just “getting older.” In this video, we break down 5 skin spots you should never ignore—what they can mean, what’s usually harmless, and exactly when to get checked.

You’ll learn:

How to recognize Actinic Keratosis (the rough sandpaper patch)

The “Three-Week Rule” for a sore or pimple that won’t heal (possible basal cell warning)

The Ugly Duckling sign + the ABCDE rule for suspicious moles

How an “age spot” can sometimes be an imposter (lentigo maligna warning signs)

The difference between cherry angiomas vs petechiae/purpura, plus the simple glass test

✅ Practical tip: Use your phone to track changes with photos (same lighting, same angle), and bring them to your dermatologist.

⚠️ Medical note: This video is for education only and does not replace professional medical advice. If you notice rapid changes, bleeding, pain, or a lesion that doesn’t heal, please see a qualified clinician promptly.
