Matthew 6:16-18 (King James Version)
16Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward.
17But thou, when thou fastest, anoint thine head, and wash thy face;
18That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.

AMEN! Even better Scripture to show us that true faith neither requires nor warrants face-painting.
