Questions & Answers about Моё лицо может покраснеть на солнце.

Russian possessive adjectives agree with the gender (and number, case) of the noun they modify:
- masculine: мой стол (my table)
- feminine: моя рука (my hand)
- neuter: моё лицо (my face)
- plural: мои руки (my hands)
So with лицо (neuter), you must use моё.
