The 22-year-old spoke out, telling The Sun that the popular E4 series leaves her with a "bad taste in the mouth".
Geldof complained: "Skins is too much. It's real in some ways. But for every handful of teenagers who are wayward and going through things that are portrayed in Skins, there are many teenagers who aren't.
"It's not just a 24/7 party lifestyle when you're growing up. There are times when you are sitting at home doing your homework and it's not just this crazy, drug-fuelled, orgy-filled thing that Skins says that adolescence is."
She continued: "It gives a bad name to modern adolescence. Smart teenagers will watch it laughing but other kids will think that's what life is really supposed to be like - and their lives are boring in comparison. It might spur them on to try and live more recklessly."
Geldof, who divorced guitarist Max Drummey after six months of marriage, has denied that drugs were behind her recent weight loss.
"Just because someone loses or gains weight it doesn't mean you've got an eating disorder," she hit back. "I think that's quite cruel. No-one should be worried about me."
