Ok, I would suggest you book a couple of facials so that you can try them for yourself. The only way to successfully retail skincare is to completely love it yourself, so try before you buy. When you look at retailing, see where else it is available. Dermalogica can be bought in department stores and Next, so will you be able to compete with these when it comes to selling it yourself. You need to get to know the brands you want to use inside out before you spend what will be thousands of pounds committing to one.
