All my skincare I bought from reseller on shopee. Did my homework and no fakes so far. This brand kiehl a lot of copy one though so I always just avoid

As in they do work and I haven't found anything suspicious, like cheap bottle label etc

Before buy it's just standard lah. If too cheap is also a flag. Some resellers also sell trial packs (which aren't meant for sale) and others do rebottling, I don't buy these but if really want cheap² should check these than messing with suspicious listing

True, rebottles typically about seller bulk buying and sell in small quantity. Great for people who want test product and not yet convinced to buy the full pack

They are sold in really really tiny volume though, if that also want cheat then seller just pure evil lol
