Drunk Elephant is a popular skincare brand founded in 2012 by Tiffany Masterson, known for its "clean-compatible" philosophy that avoids the "Suspicious 6" (essential oils, alcohols, silicones, sunscreens, fragrances, SLS). Acquired by Shiseido in 2019, it focuses on biocompatible, high-pH, and effective ingredients to improve skin health.
