Yeast will produce a large number of reactive oxygen molecules during fermentation, which has whitening effect on skin.
Theoretically, oily skin can use yogurt instead of milk.
But yogurt is sticky when yeast is dried, and it is difficult to stir.
Can yeast do any harm to the skin?
If you don't have sensitive skin and don't use it often, there is no problem.
By the way, if you feel uncomfortable when using it, please wash it off immediately, because everyone's skin acceptance is different, and the biological activity of yeast may cause some skin allergies.
After mixing a little yeast and smearing it on the inside of elbow or ear, there will be no adverse reaction within half an hour.
This mask can increase the oxygen content of the skin, make dull skin feel transparent (that is, we usually say that the thick stratum corneum becomes smooth), and also has the function of whitening the skin and making the skin color more uniform.
However, there are a few points to remind everyone:
1, please use skim milk for oily skin.
2. Please use it immediately after finishing, because it is easy to dry and agglomerate.
3. Because it contains active yeast, it is easy to cause allergies, so sensitive skin should be used with caution.
4, once a week, not commonly used.
