Strictly speaking, aspirin has a certain whitening effect, because the active ingredient of aspirin is acetylsalicylic acid, which is found in many whitening cosmetics, but it should be noted that acetylsalicylic acid in aspirin is a water-soluble ingredient, which is difficult to be absorbed by the skin through the stratum corneum. If you use aspirin for whitening, the incorrect ratio may cause damage to the skin and may cause more damage to the skin, so it is recommended that patients should not blindly use aspirin for whitening to avoid causing more harm to the skin. If you want to whiten your skin, you can do a good job of sun protection, apply sunscreen, and eat more vitamin C rich food, which has an antioxidant and anti-aging effect.
