Is it normal to not smell your own perfume?
Yep.Totally normal
Yes. You can get used to your perfume quickly, so you may stop noticing it even while other people can still smell it.
Your nose is good at tuning out steady, familiar smells—a process called olfactory adaptation. Perfume is especially easy to stop noticing when you wear it often or apply it near your face.
Other people may still smell it, so not noticing it yourself isn’t a reliable sign that you need to put on more. If you suddenly can’t smell other things either, consider getting that checked; otherwise, this is a normal nose doing its thing.
