Salicylic Acid is a commonly used chemical found in drugs, cosmetics and skin care products. Here is some information about salicylic acid safety and precautions:

Safety:

Salicylic acid is generally considered relatively safe, but there may be some risks for certain groups of people. If you have specific health concerns or are allergic to certain ingredients, it is recommended to consult a doctor or dermatologist before using salicylic acid.

Salicylic acid is used in low concentrations and usually does not cause serious side effects. However, high concentrations of salicylic acid may cause skin reactions such as irritation, redness, dryness, and peeling.

For sensitive or broken skin, a skin test should be done before using salicylic acid to make sure it won't cause an allergic or irritating reaction.

Avoid getting salicylic acid into sensitive areas such as eyes, lips, and open wounds to prevent discomfort or irritation.

Precautions:

Before using salicylic acid, it is recommended to conduct a skin test. Apply a small amount of the salicylic acid product to a smaller area, such as your wrists or behind your ears, and watch for any discomfort or allergic reaction. If symptoms such as redness, itching, or irritation occur, you should stop using salicylic acid products.

Follow the usage instructions in the product manual. Use the right amount of salicylic acid products and avoid overuse, which can cause skin irritation or dryness.

For those new to salicylic acid use, it is recommended to start with a low concentration product and gradually increase the concentration to allow the skin to adapt and reduce the risk of adverse reactions.

While using salicylic acid, avoid using other irritating products at the same time, such as alcohol products or other products containing fruit acids, vitamin C and other ingredients, to avoid increasing skin sensitivity.

During the use of salicylic acid, attention should be paid to keeping the skin fully moisturized, and using mild moisturizing products can help reduce dryness and discomfort.

Please remember that the above information is for reference only. If you have specific health concerns or are concerned about salicylic acid use, it's best to seek the advice of your doctor or dermatologist.
