If you're a 4/10, looksmaxxing can only take you at the best to a 6/10, Meaning if you're say 18-22 you might be bale to get a 4/10 gf. However she'll grow dissatisfied and leave you the minute you start slipping up.

And if a chad ever offers her the chance, she'll leave you for him. Looksmaxxing is only worth it if you're a 5.5+ and even then. most chads I know don't respect foids. They know how slutty they are, and that they'll monkey branch whenever they can.
