1. Lighten dark spots

One of the most important effects of arbutin is to lighten dark spots and whiten the skin. Generally speaking, melanin in the human body will increase with age, and melanin will cause skin coloration. At this time, if arbutin is used, some components in arbutin can inhibit tyrosine in the body. The activity of acid enzyme prevents the oxidation of tyrosine, affects the synthesis of dopa and dopaquinone, inhibits the formation of melanin, and reduces the deposition of skin pigment, thereby achieving the effect of lightening pigmentation and whitening the skin. Therefore, arbutin is used in many cosmetics.

2. Pain relief and anti-inflammatory

Arbutin also has analgesic and anti-inflammatory effects. In our daily life, the main raw materials for making medicines for burns and scalds include arbutin, which has strong anti-inflammatory and analgesic abilities. It can effectively reduce inflammation, reduce swelling and speed up wound healing.

3. Antitussive and expectorant

Arbutin can also play an antitussive and expectorant effect. This substance can increase the mucus secretion of the organs, prolong the incubation period of ammonia-induced cough, and reduce the number of coughs.

4. Sterilize and stop diarrhea

Arbutin also has the effect of bactericidal and antidiarrheal. Some common medicines for the treatment of gastroenteritis in daily life also contain a certain amount of arbutin, because arbutin has anti-inflammatory, antidiarrheal and bactericidal effects. At the same time, it can also prevent the virus from continuing to breed and multiply in the stomach.

The above are the main functions of arbutin, among which whitening and lightening is the most important effect of arbutin, so many whitening products will add arbutin. However, it should be reminded that when using arbutin, it is necessary to avoid sunlight exposure. If it is used improperly, it will not only inhibit melanin, but also lead to the precipitation of melanin. Therefore, you must pay more attention when using products containing arbutin.

1. Whether it is β-arbutin or α-arbutin, it can only be used externally and cannot be taken orally. Everyone must remember this to avoid adverse effects on the body.
