The Red Blemish Clear Soothing Cream contains 5% Centella Asiatica Leaf Water—the highest OTC concentration approved by Korea’s Ministry of Food and Drug Safety—along with zinc PCA that reduces sebum oxidation by 89% in 3 hours. Dr. G’s factory holds ISO 22716 certification with a dedicated “Low pH Production Line” preventing ingredient degradation.
