There were some seriously good self-tan innovations this year, but by far my favourite was the Tanologist Self-Tan Drops (£25) that can be mixed into face or body moisturiser for custom tanning. A few brands launched these over the Summer, but Tanologist just pipped others at the post thanks to the cool branding, long-lasting colour, and scent (or lack thereof). The medium shade left me a lovely shade of bronze, which lasted a good five days and faded evenly. One tiny bottle lasts for ages and is great for travel (where you can mix the drops into after sun, or hotel body lotion miniatures, to save packing big bottles). My favourite thing? They're colourless, so no dirty sheets at home or away. — GC
