The effects and hazards of salicylic acid

Many things have both good and bad sides, just like drugs have many side effects while treating human diseases. Salicylic acid is an ingredient in cosmetics, and many acne-removing medicines also contain salicylic acid. The function of salicylic acid is to disinfect and remove acne, but it also has certain side effects when people use it. Long-term use can cause human dependence. The following is a detailed introduction to the effects and hazards of salicylic acid.

The dangers of salicylic acid in skin care products:

Nowadays, many well-known cosmetics contain salicylic acid. The Department of Health has announced that cosmetics containing salicylic acid must be accompanied by a warning to remind the public not to use them for a long time, and children under three years old are not allowed to use them either, because long-term and large-scale use of salicylic acid may cause side effects such as tinnitus, dizziness, and vomiting.

Salicylic acid is commonly used in cosmetics as a keratin softener or acne prevention and treatment agent. Several medical reports have pointed out that when used, local skin may cause erythema, itching, and stinging. Large-scale or long-term use may cause the "salicylic acid effect", resulting in tinnitus, dizziness, nausea, vomiting and other phenomena. In order to use salicylic acid products safely, warnings need to be included on such products.

There are many derivatives of salicylic acid, including aspirin, which is used to relieve fever and pain. If you have a chronic keratinization disease and must use salicylic acid for a long time, or if the use area reaches 30% of the body, you must be particularly careful about the salicylic acid effect. For general skin care, using a small amount should not cause side effects. Salicylic acid is easily absorbed by the human body. Long-term use by patients with chronic keratinization may change the body's pH value and cause adverse reactions. Salicylic acid is widely used.
