Petal Rebel in my opinion is a unique colour because it's both light and bright at the same time. As someone who prefers bright or dark lip colours I release there is a time and a place for them so Petal Rebel is a perfect alternative for me. The only other colour that is similar that I've come across is Benefit's Posie Tint which is drying and uncomfortable on the lips.
The formula of Petal Rebel is very moisturising and comfortable but because of that it comes with some faults. I need to apply a couple of layers to get the opaqueness that I prefer but that may just be an issue if you have pigmented lips like me. Another thing I don't like about it is that Petal Rebel has very poor staying power. I usually pair it with a lipgloss to make it last longer.
Overall Petel Rebel is an affordable and pretty everyday shade. Although I would recommend the Maybelline Color Whisper line I think I'll get a different colour if I ever run out of this.
