Citric acid is widely used as a pH adjusting agent in creams and gels of all kinds.
In this role it is classified in most jurisdictions as a processing aid and so does not need to be listed on ingredient lists.
Citric acid is an alpha hydroxy acid and used as an active ingredient in chemical peels.

柠檬酸属于果酸的一种,主要作用是加快角质更新,常用于乳液、乳霜、洗发精、美白用品、抗老化用品、青春痘用品等。角质的更新有助于皮肤的中黑色素的剥落,毛孔的收细,黑头的溶解等

I have very sun sensitive skin and sunscreens with citric acid make my skin more photosensitive. I avoid it in most of my skincare products.
