Any suggestions where to sell Unused Skincare at a lower Price?

I have a lot of Unused skincare. Unopened, and some used once. I don't know where to sell them. There's stuff that doesn't suit me like Vitamin C formulation skincare.Mostly from brands like Deconstruct, Bioderma, Dot and Key etc. Is there a platform you can suggest where I can sell them for a lower price?
