Eat more fruits and vegetables. Although I don't like vegetables, fruits are daily necessities, such as tomatoes. Stick to eating one every day. There is also lemonade, preferably lemon soaked in warm water, which is more popular recently. Even Fan Bingbing, Guan Xiaotong, Jiang Shuying and other female stars are drinking passion fruit lemon honey water. If you insist on drinking, there is still some whitening effect, but try to drink it in the afternoon.
