When it comes to the tingling of fruit acid toner, there are three reasons why
fruit acid toner stings when used.

One is that the skin is not tolerated enough. Human skin is different in nature. Or if the skin is delicate, it is usually not stimulated by fruit acid. When you use fruit acid toner at first, the skin cannot bear its strength, and then there is a tingling feeling. Like a delicate flower that has been through wind and rain at the beginning, the body is soft and difficult to bear. Those who use fruit acid products for the first time often encounter this situation. This is the stress response of the skin to fruit acid.

The concentration of the two is inappropriate. The effect of fruit acid depends on its concentration. However, if the concentration is too high, although it can quickly show the effect, it will also stimulate the skin. Businesses seek quick-acting, or have used high-concentration fruit acid in toners, but users do not carefully examine their own skin conditions, rashly use it, and the tingling occurs. Just like a good medicine, if used in excess, it will hurt the body. Therefore, when choosing fruit acid toner, you must check its concentration and measure the skin.

All three, the skin barrier is damaged. Skin barrier, like the city's barrier, protects the skin within. If the skin has been exposed to sun, excessive cleaning, etc., and the barrier is damaged, the skin is sensitive. At this time, use fruit acid toner, the fruit acid goes straight into the deep layer of the skin, stimulates nerve endings, and the tingling starts. For example, if the city wall is destroyed, foreign enemies are easy to invade, the skin loses its solid protection, and the "invasion" of fruit acid is inevitable.

If you want to solve the tingling dilemma of fruit acid toner, you should first test the sensitivity and then use it according to the nature of the skin, choose the product that suits the concentration, and protect the skin barrier. In this way, you can use fruit acid toner to avoid the pain of tingling and obtain the effect of skin beauty.
