Salicylic acid is irritating to the skin.
If we have bought skin care products containing salicylic acid, we can notice that the concentration of salicylic acid in these skin care products will be very strict. Because if the concentration of salicylic acid is too high, it will cause great irritation to our skin. At the same time, because some people's skin is naturally sensitive in life, even if the added concentration of salicylic acid is within the normal concentration range, they will still feel very irritating when using salicylic acid, and some redness and even itching will occur.
In this case, we can first try to reduce the frequency of using salicylic acid and let our skin gradually establish tolerance to salicylic acid. We can use it once a day first, and then see if the skin will have obvious irritation after one week. If the irritation is improved, salicylic acid can continue to be used, and if it is not obviously improved, it must be stopped.
Function and function of salicylic acid
The most important function of salicylic acid is to speed up the metabolism of our skin, remove excess keratin and improve the oil secretion of our skin. The reason why we have acne on our faces is largely due to the exuberant secretion of oil and excessive accumulation of keratin on our faces, which in turn blocks pores. Therefore, if our skin can withstand the stimulation of salicylic acid, long-term use can effectively improve the acne problem. In addition, salicylic acid, a problem that many girls are particularly concerned about, can also play a certain role in improving.
