Should I continue selling this product? 1:1 perfumes

hello for context, I am a teen and I sell one to one colognes/(Perfumes). I always tell them upfront even if they don’t ask and I sell them for 20-50$ each depending on quantity and sometimes even less around 15$ if they buy 80pcs or more I sell online and on marketplaces like facebook the problem is that they truly don’t last the smell is pretty similar they just last for 15-20 mins I feel kind of bad selling this product, but I make a ridiculous amount around 12k a month revenue. Is it ethically wrong or deceptive for me to sell these products? longevity is OK if you spray more than 5 but then again not too sure what’s going into these I don’t believe it could be that bad because most beauty products are manufactured in China anyways. I think it’s worth it for the money but people still sometimes complain even after I tell them it’s one-to-one and it’s kind of starting to annoy me as you paid $30 for a fragrance that retails for 300$… what amazes me even more is that some people genuinely think it’s authentic at this price point so I always tell them no matter what but every now and then (pretty rare) I get a complaint. 😭
