People lie all the time even outside of their appearance, if you always take everyone at face value (lol pun) you're in for a rough time
If most of the women/men you see day to day are instathots and ewhores online, you've pretty much guaranteed yourself to have whiplash over it if you let it matter that much to you. Spending more time around down to earth ppl offline, and less around bougie socialites on youtube who get their ideals from media can help.
It's really not your problem if dumb ppl online will really be fooled into thinking a majorly made up face is natural. Most of those people are A. Kids or B. Not very bright. They're in for their own rough awakening one day. All that shit is temporary anyway, when you find someone who loves you for you it doesn't really matter anymore.
If your primary motive is simply getting attention, makeup is one easy way to obtain it, for sure. But attention doesn't guarantee happiness. It's just an ideal some people hold, not a requisite for a good life.
Personally, makeup is just something fun you do for datenight or parties, and light concealer with mascara for work helps hide the soulsucking drain of your lifeforce you experience day in and day out as a wagie with no hope for the future, so people don't ask you if you're sick all the time & report you to mgmt. But I digress
