Please don't take this the wrong way because offence is certainly not intended :hug: but I think certain brands of cosmetics see their product as being 'cheapened' by mobile therapy IYKWIM? I think some cosmetic companies like to maintain a certain amount of exclusivity by deciding who uses and sells their products and who doesn't. I know they don't like too many salons in one area carrying their brand.
If you were to go mobile in an area where there was, for example, already a Dermalogica Salon, then your service would detract from the exclusivity for Dermalogica being offered by the salon. Does this make sense? HTH. Clarins are exactly the same, in fact a therapiust has to have a certain square meterage of salon space to use and retail the products including a big window display. Can't say I would want CLARINS hanging out of my home salon window.
