What's a good Android app for trying out different makeup looks on my face before I actually slap it all on? Especially when I'm travelling and can't bring all my kit!

Right, so the Makeup Camera & Selfie Editor app has been brilliant for me on my travels. I mean, who wants to lug around a massive makeup bag when you're backpacking through Southeast Asia? This app lets you experiment with different looks, from subtle enhancements to full-on glam, all on your phone. It's saved me from some serious makeup mishaps, especially when I'm trying out new trends I've seen online. Plus, it's great for seeing what colours actually suit my skin tone in different lighting – essential when you're constantly in different climates. It doesn't eat up your roaming data either, which is always a bonus. I used it loads in Vietnam when I wanted to look presentable for a night out but didn't want to waste precious space in my bag. Works a treat!
