@Kaylz - Would your partner, or your Mum help you decant some cream into a reusable tube that could be refilled as many times as you need it to be?
I have been really so impressed by Lidl's own Cien brand of handcream, in the "Intensive" variant. It disappears in a moment and carries no heavy scent. How about if it could be taken from a fresh box, into a food bag you took into the store? Nobody would have touched it before you?
If you wanted to decant something, then our Lidl currently have refillable silicone tubes, in a pouch, sold in a sealed package.
Finally, if you have a cream you like but it's a bit "heavy", you could add something like a little aloe vera gel to make it a little thinner? That would ten go into a reusable tube, small squeezy bottle or pump maybe a pump pot, from say, handwash, for dispensing.
