The best subway lines and stations where people can put on make-up have been revealed in a new study.
Visual experts Lenstore have analyzed the 11 underground lines and taken into account things like average temperature, how busy the line is, how fast it is, and how much of it is above and below ground.
All factors were considered helpful in applying a good face with natural looking makeup.
Metropolitan was voted the best line – mainly because it is mostly above ground (76.5 percent) and allows for good light.
It is also one of the quieter lines with an average number of passengers of 352,464 people and has air conditioning, which means that make-up does not slip off travelers’ faces.
Other Tube lines that topped the list included the Circle line, Hammersmith and City, District and Bakerloo.
At the other end of the scale, the research found that the Northern line is the worst Tube line for applying makeup.
This is because it is one of the busiest underground lines – with an average number of passengers of 1,123,342 – and has a high average temperature of 32.4
Victoria, Central, Piccadilly and Waterloo & City were also below par, the research found.
Lenstore also analyzed all 53 subway stations in zone one, across four categories, to determine which one was best to apply makeup again while waiting for the next train.
These categories include the average temperature, whether below or above ground, average station inputs on a weekday, and the age of the station.
Southwark came over top trump, with Tower Hill, Bayswater, Pimlico and Edgware Road (Circle Line) completing the top five.
Bank and Monument topped the list as the worst make-up-friendly stations.
Lenstore’s experts said that although it is sometimes necessary to apply make-up on the tube for time-consuming Londoners, it is not the ideal place to put on your face.
Expert optometrist Roshni Patel said: “Although in some cases it may be necessary to put make-up on your commute, I would not suggest making a habit out of this as you risk damaging your eyes.
“Firstly, the tube is not the most hygienic place to apply makeup, and you can open your eyes to various bacteria and infections. In addition, trains are not the most robust, and since they are busy most of the time, there is a large chance that you can stab yourself in the eye with your mascara stick or eyeliner, resulting in damaged corneas. “
