    Neither. Propanediol is just a protic solvent and MSM a solid which, due its close relation to DMSO, is often called a penetration enhancer without reliable citation. MSM may have other effects on skin penetration as you can read HERE (not saying that this is a reliable source nor that the results may be extrapolated).

    You could look at a small amount of squalane, or glyceryl oleate.

    I don't think either are true penetration enhancers the way Dimethyl Isosorbide is, for example. It's like when people say glycerin is a penetration enhancer.

    Look up forum’s archives. It was discussed many times.
