At some time or another, all of us will have smeared a bit of sample concealer or eyeshadow on the back of our hands to test out the colour - although few people would actually think of applying samples to their faces every day as part of their make-up routine.
For 18-year-old Amira Saskia however, beauty shops can double as “mobile make-up collections”, with the London-based social media manager regularly applying public testers to her face while getting ready.
In a number of TikTok videos that have since gone viral, Amira can be seen painting her face using beauty products dotted around on counters throughout the city.
