I recommend a recipe that I am using now. In fact, the bean curd residue left by squeezing soybean milk every day has been ground very finely, which is a very good whitening product.

Add honey, pearl powder (available in Tong Ren Tang) and egg white into the bean curd residue in a small bowl, mix well and apply 15-30 minutes. The whitening and freckle removing effect is very good.
