And unlike harsher treatments that can leave your skin feeling dry or tight, this formula keeps things balanced, comfortable and happy.\n\nDoes Dear, Klairs Blue Youth Drop Serum work?\n\nYes – Dear, Klairs Blue Youth Drop Serum delivers visible results, and quickly too. It has been clinically tested by the ProbeM Skin Research Center and shown to improve multiple skin concerns, including:\n\n46.53% reduction in physical skin irritation in 3 minutes\n\n21.15% decrease in heat-induced redness in 3 minutes\n\n23.21% improvement in post-acne pigmentation after 4 weeks\n\n63.42% reduction in excess sebum and oil after 4 weeks\n\n5.76% increase in skin elasticity and firmness\n\n2.55% improvement in visible facial lifting\n\nThe formula also recorded a 0.00 irritation index, meaning it’s considered safe for sensitive skin.\n\nDoes Dear, Klairs EGF Blue Youth Drop Serum help with rosacea?\n\nWhile the EGF Blue Youth Activating Drop Serum isn’t a treatment or cure for rosacea, it may support your skin in other ways.
