She also reviews the signs of retinoid overuse, including redness, peeling, burning, dryness, and increased sun sensitivity. She discusses how to recognize actinic keratoses, common precancerous skin lesions caused by cumulative sun exposure, and explains why rough, scaly patches on chronically sun-exposed skin should be evaluated by a dermatologist. Dr. Dray also answers a question about post-inflammatory erythema (PIE) after acne, explaining why persistent redness develops, how abnormal blood vessels contribute to its appearance, and which skincare ingredients and in-office treatments may help improve it over time. Other questions include whether the cosmetic ingredient adapinoid behaves like adapalene, whether sonic facial massage devices have evidence to support claims about improving skin or facial bone health, how UPF laundry additives can increase the sun protection of clothing, what the research says about astaxanthin supplements for skin aging, whether hair dye is safe for people with rosacea, and more.
