Is it permissible for a woman to uncover her face to kiss the Black Stone in the presence of men?

Kissing the Black Stone is a confirmed Sunnah during the circumambulation (Tawaf), if it is easy to do so without jostling or causing harm. If it is not possible, it suffices to point to it with the hand, especially for women, while ensuring their faces are not uncovered in the presence of non-mahram men.
