Do you guys still use DMSO ie. Dimethyl sulfoxide and DMI i.e. Dimethyl Isosorbide to help with your skin lightening products? They are "absorption enhancers" that help skin care go deeper than the upper layer of skin. DMSO goes bloodstream deep while DMI goes skin deep. I'm asking because most of the post talking about them are from years ago and I'm curious if anybody still uses it and what your results are after using them.
