Aspirin is an anti-inflammatory drug for antipyretic and analgesic, the chemical composition is mainly acetylsalicylic acid, the cosmetic effect is poor, not a special beauty drug. The main cosmetic effect is because salicylic acid has a certain exfoliating effect, but this drug is easy to form a gastrointestinal reaction with long-term use, which can stimulate the gastric mucosa and lead to ulcers. In addition, acetylsalicylic acid also has a certain role in inhibiting platelets, so long-term use of aspirin can also lead to bleeding tendencies. Salicylic acid itself can be toxic in excess, and in severe cases, excessive heat and dehydration, acid-base balance imbalance, etc. Therefore, there is no evidence-based basis for using aspirin for cosmetic purposes.
