Albumen, commonly known as egg white, is one of nature's highest quality protein sources. It's also packed with niacin (Vitamin B3), riboflavin (Vitamin B2), selenium, magnesium, calcium, phosphorus, potassium, and a complete amino acid profile. Four ways albumen works in our Egg White Pore line: Regulates excessive sebum Eliminates pore-clogging impurities Tightens pores and minimizes their appearance Eradicates skin bacteria The high level of protein in albumen, along with its natural low-moisture state, makes it a very effective moisturizing and tightening agent. Albumen is also a natural anti-inflammatory. All of these virtues make egg white egg-cellent for exfoliating, refining pores, and controlling excess oil, as well as anti-aging effects! SKINFOOD's Egg White Pore Mask is a pore-refining cleanser with egg white extract that penetrates deeply into pores to remove pore-clogging oil.
