Murad -- the skincare company to tons of celebs -- is going through some big changes ... not the least of which being its president filing for divorce after 10 years of marriage.
Hilarie Murad -- daughter of famed dermatologist, Dr. Howard Murad -- filed the docs Tuesday in L.A. ... citing irreconcilable differences with Gerard Murphy.
Murphy and Murad have 2 children, ages 9 and 7. She's requesting legal and physical custody. The divorce comes just 2 months after Murad was sucked up by another skincare giant, Unilever, for an undisclosed amount.
