Skincare expert HAROLD LANCER credits his longtime client Denise Richards with having the best skin in Hollywood because she knows how to look after herself.

The revered dermatologist has been treating the former Bond girl's skin since she was 19 and he's thrilled to boast she's one of his clients because she never takes her looks for granted.

He explains, "She's a natural beauty and it's just a matter of maintaining her skin.

"(It's all about) nutrition, diet are exercise, which she's a fanatic about - and sun-block use. (She's also into) regular cleansing and exfoliation."
