The actress Charisma Carpenter, known by her role in the TV show Angel and Buffy, is rumored to have had breast implants. There is not a big difference between pictures of her, but more a change in her whole style. Her breast doesn't look too high or too hard. Taking this in count, there are two options, one is that she got the implants but a small size, proportional to her body and the second one could be that she is just using a wonder bra.
About considering plastic surgery she said for Sky: "Absolutely! My father has overhanging eyelids and I tend to frown a lot and eyebrow-act a lot. So I think that in the industry I'm in, if I could bear to go under the knife, I think, "Great, knock yourself out." But I think once you start really messing with nature, it can backfire and there's nothing you can do about it. I've seen some pretty bad jobs."
