My friend used my cream without Castor oil . Her face was developed pimples. But using the cream with castor oil, her face doesn’t have pimples. Is castor oil having high % (90%) of ricinoleic acid that helps ?

@Perry! if they claim medical grade skincare, have they to required FDA approve? For testing, they carry the testing by themselves?

Thanks

@LuisJavier, China products are well known poor quality. For ingredients for facial cream, I suggest that you must be careful.
Even very cheap I do not want to buy from china.

@ngarayeva001
oil free is not meaning that there is no oil in the formula.
but it means that the cream absorbs so quickly and leave very little oil that can not be noticed

C13-15 alkane is compatible with silicons. I love C13-15 alkane bc it is natural and derived from sugarcane
