Washing your face with rice washing water has whitening effect, but rice washing water is easy to produce bacteria after a long time, so it is not recommended.

Whitening can be achieved in the following ways:

Adequate sleep can ensure smooth and delicate skin.

You can apply egg white and honey to your face, which has whitening effect.

Eat more fresh fruits and vegetables and foods rich in vitamin E and vitamin C, which have antioxidant effect and can beautify the skin.

Using some whitening and hydrating plant cosmetics can also improve skin quality.
