NoPillow is a very underrated looksmaxxing tool. It puts your head in a more neutral position so it helps with mewing which improves your lower third. It's easier to mew at night without a pillow which will lead to all the common mewing benefits like forward grown chin and maxilla, raised hyoid bone etc. Pillowcases gather lots of dirt even if you can't see it and considering you naturally change position during your sleep your face may be touching the pillow even if you think you sleep on your back. With nopillow you will therefore have better skin along with better lower third.
