Rachel Bilson: Little Dom's Darling

In personal news, the former “O.C.” starlet get assistance for her enviable complexion from Debra Jaliman, M.D, who recently released the new book “Skin Rules” where she gives her best kept secrets on keeping a gorgeous face.

Removing your makeup before going to bed is a rule that Dr. Jaliman says is key, explaining, “I cannot emphasize this enough: Never go to bed without cleansing your face. If you don’t, the results will be clogged pores and breakouts. If you’re really too exhausted to wash your face with water and cleanser, at least have cleansing pads by your bed and use them to wipe makeup off.”

The dermatologist to the stars also advises that using the right makeup can make all the difference, explaining, “People with acne cannot use heavy foundations and oily concealers, period. I’ve had several celebrity clients whose acne did not clear up until I personally spoke to their makeup artists—all that heavy TV makeup was ruining my carefully prescribed skincare regimen. Every major makeup company now makes oil-free and non-comedogenic foundations. People with very oily skin can use mineral foundations, which keep skin matte longer.”
