What should I do if I feel a stinging sensation on my face after using salicylic acid? Why does it sting when applying acid?

Acid peeling has always been a skin care method that many people like. Acid peeling can exfoliate the skin's stratum corneum, brighten the skin tone, stimulate potential inflammation in the underlying skin, and make the skin smoother and more delicate.

If you feel a stinging sensation on your face when using salicylic acid, you can reduce the frequency of use appropriately. Salicylic acid is an acidic ingredient that can fight against aging cuticles on the face, making the skin on the face relatively thin and fair. Salicylic acid can also improve acne and enlarged pores, and has a certain effect on deep cleansing of pores, so salicylic acid is a face brushing artifact. However, although salicylic acid is powerful, it should not be used frequently, especially for dry and sensitive skin. Long-term use of salicylic acid will cause the ecosystem on the face to be destroyed, and make the thin stratum corneum even thinner, so this type of skin must be used with caution. For healthy oily skin or mixed oily skin, salicylic acid is a very powerful tool for refining and smoothing the skin. Fruit acid or salicylic acid can be used 1 to 2 times a day. Generally, salicylic acid can be used after washing the face and using lotion, because after using lotion, the cuticle of the skin has absorbed enough water and become soft, and then acid brushing will be more effective. Salicylic acid does not need to be cleaned again and wait for it to be absorbed before using subsequent skin care products such as lotion or cream. It is normal to feel a slight stinging sensation when using salicylic acid. In more severe cases, redness, swelling, or peeling may occur. Because the pH value of salicylic acid is generally around 3.5, the stinging sensation is somewhat obvious, but it will be slightly alleviated after a period of time after the skin is shed. If the skin stinging is severe, you can reduce the frequency of use or use it locally in small amounts.

It is normal to feel stinging after brushing acid on the face. Some people may also experience redness and acne, so don't worry, it will return to normal after a certain period of time.

Sensitive skin brushing acid can cause allergic reactions on the skin, which will not only cause redness, itching and stinging, but may even cause new skin problems and damage the skin barrier. To a certain extent, brushing acid is a method to promote the shedding of old cuticles, so people with thin cuticles will make the cuticles thinner, the skin will become more fragile, and more sensitive skin problems will occur after using it. It is best not to use some makeup products after brushing acid, so fairies who love beauty must not wear makeup. It is not recommended to use some irritating cosmetics when the skin is relatively fragile, and it is best not to use some functional skin care products and masks.

Acid brushing refers to applying skin care products containing acidic substances on the face, such as salicylic acid, fruit acid, etc. Acid brushing can soften the cuticle and promote the speed of skin metabolism, thereby solving skin problems such as acne marks, pustules, and closed comedones. However, acidic substances are corrosive, so do not brush acid too frequently, otherwise it will not be skin care but disfigurement. After acid brushing, tingling, itching and acne may occur, but it will not last for a long time. Frequent acid brushing will not only not improve the skin, but also make the previous problems of the skin more serious, and will damage the stratum corneum of the skin, causing the skin to become more sensitive. Therefore, be sure to brush acid under the guidance of professionals. In addition, the stratum corneum will become thinner after acid peeling. At this time, the skin is very fragile and more likely to get tanned than usual, so you must pay attention to sun protection and moisturizing, or it is best to peel acid at night.
