Note: This is a review of the Saban Brand English dubbed version of Glitter Force. Also Note: for now, this review is only for the first set of episodes of Glitter Force (the first 20 episodes of the English adaptation). When the rest of the episodes are released, I will update this review.

Violence / Gore:
Glitter Force has a LOT of fight scenes. But the Glitter Force fight with their Glitter Powers (usually), not with actual weapons. There are a few kicks and hits, and the girls get tossed around sometimes, but it's not gruesome at all. The ending of season 1 (around episode 20) has a more serious fight scene in which the action is just a smidge more violent (it just has a more serious feel, and the villains look a little scarier than usual).

Nudity / Sexual Content:
None that I recall. Clean, clean, clean.

Potentially problematic theological themes:
The Glitter Force gain their powers through magic makeup compacts. They fight with magic against evil adversaries who transform everyday objects into living "monsters" for them to fight. The adversaries from the Shadow Realm are trying to resurrect their master, who is in a sleep-like state until enough despair is collected from the real world to revitalize him.

Other potentially problematic themes:
None that I recall. Clean, clean, clean.

* So I know what you might be thinking: They fight with glitter powers! They're using powder-puffs! This is way too much!
Actually, I very much enjoyed Glitter Force. The characters have enough personality to keep the show lively. The humor (in the English version at least) was quite funny - even the softly spoken bits in the background made me smile sometimes. They just say such off-the-wall things (especially Emily)!
This show was clean, entertaining, and just mad me smile. It was not an overly happy, skip-around-for-no-reason-and-drive-me-insane sort of show... it was refreshing. No real content issues, either. Imagine Power Rangers (you know, master villains send out a lackey-per-episode who causes problems but is defeated)... it's like that, but with more glitter.
The reason I couldn't give this show a 10 was that the defeated mini-villain per each episode could make the show feel lengthy. Not to mention the complete lack of love interests for the characters. But hey, Glitter Force was still great.
Spoiler alert: Glitter Peace is so funny without trying. P.S. Pop is the best character. P.P.S. I was very impressed with the English voice actors! (especially the voices of Rascal, Lily, Ulric, and Pop of course. Todd Haberkorn was noticeably fierce.)
