Why cant you wear makeup on Yom Kippur?

On Yom Kippur, which is a day of repentance and reflection in Judaism, many observant Jews refrain from wearing makeup as part of the overall emphasis on humility and self-denial. The day is dedicated to spiritual cleansing and atonement, and avoiding cosmetics is seen as a way to strip away distractions and focus on the inner self. Additionally, it aligns with the general prohibitions on physical pleasures and adornments during this solemn day.
