I've had this redness for nearly 2 weeks. It randomly came &covered my entire cheek, my other cheek also has this but at less severity. This area is also dry, but there is no itching or irritation which cancels out allergic reaction, skin feels hot. I've been applying hydrocortisone & it's making it worse. I have NOT changed my skincare, Only difference is its gotten cooler, but thats never impacted my skin. One other thing, I do have rosacea, could it be rosacea spreading? It happened overnight
