Actually a very short line-up, because there’s just a cleanser (£5.75 here*, absolutely excellent) a Hydra-Prep Lotion (one step too many for me, but it does actually hydrate in quite a startling manner), a Deep-Treatment Serum (£8.11 here*, and again, startling in its effectiveness) and the Supreme Cream moisturiser (£9.83 here*).
So there’s a membership fee and you need to choose your level of membership according to how much you want to spend per month, but the spend isn’t based on the cost of the product to members (so for the Supreme Cream, £9.83)
If you wanted to buy this cream, then, you’d need the membership level that lets you spend £100 per month, which costs £10 per month in fees.
Still miles cheaper than any cream I can think of that’s this good, and if you didn’t want the cream every month then the next month you might buy tinted moisturiser, or serum, or retinol products.
