On the reason for the tingling of fruit acid
Those who use fruit acid in the world have a tingling feeling. Why is this? The nature of covering fruit acid is lively and intense, and the skin touches suddenly. If it is intolerant, it will sting.

The surface of the skin is protected by keratin. However, fruit acid can dissolve keratin. When it is first used, the keratin is loosened, the skin barrier is slightly damaged, and external stimuli are easy to enter, resulting in tingling. And fruit acid has the ability to promote penetration. If the skin is not used, nutrients and irritants will accelerate into it, which is also the cause of tingling.

Furthermore, individual skin varies. Sensitive skin is already delicate, and fruit acid is even more irritated. Or the skin has a disease, such as rash, inflammation, etc. In case of fruit acid, the tingling will be exacerbated.

If you want to reduce the tingling of fruit acid, first test the sensitivity. Take a little and apply it to the wrist or behind the ear, and then observe it. If there is no discomfort, you can use it. And when using fruit acid for the first time, the concentration should be low and the frequency should be less, so that the skin can gradually adapt. When using it, it should also be hydrated and moisturized to strengthen its barrier. In this way, it may relieve the pain of fruit acid tingling, so that the skin can benefit from fruit acid and suffer less from it.
