It is best to avoid such beautifications while fasting. Fasting has a form and soul. The soul of fasting entails shunning indulgence, learning self-restraint and overcoming passions and desires, and nurturing mindfulness of Allah.

 

Therefore, we should try our best to avoid indulging our passions. Having said this, I cannot firmly state that using lipstick would break the fast.

 

Almighty Allah knows best.
