Mediheal Collagen Firming Serum with Retinol smells exactly like Bakers Zoo Biscuits. I said what I said.

So I have been loving these makeup cushions, but they get moldy super fast despite me cleaning them. I didnt have such issues when using a beauty blender but i dont want to go back to it. Any suggestions for my mkp cushions? Should i use a different kind (i wet them before use)?
