Reliable eBay sellers?

[Shmallow]

Can anyone recommend any tried and tested ebayers for beauty stuff? I'm after a particular serum that has really been good for dd's skin, but it was a bargain TK Maxx find and is genuinely spendy normally. It comes up on eBay but feels risky!

Can’t help with ebayers , but also look on
Vinted … although there is the same risk

Yeah, it's not a bad idea to have a look. Such a minefield though, I'll probably just end up sinking the cost into buying direct. I don't want to arse around trying to replicate it with other products if this one is working for her.

What product is it and we could maybe recommend where has good discounts? I generally look at what all items the seller has for sale before buying and getting a sense of whether it’s real or not x
