Drying or Ethyl alcohols, also known as denatured alcohols, have often been used in cosmetics for their preservative effects and as a solvent to increase the solubility of ingredients. Increased solubility allows for the formulation to have a smoother, creamier feel. The use of these alcohols has been known to cause irritation and can trigger rosacea flare-ups. Continuous use can disrupt the skin’s protective barrier and make it difficult for skin to naturally retain moisture.Drying alcohols dry skin making it appear wrinkly and worsen rosacea
