I purchased this foundation around 3 months ago and I have finished one bottle. The coverage is medium but it is buildable without looking cakey. There is a large range of shade. although it oxidizes throughout the day it still lasts. The Most I have worn it is around 14 hours and it still looked decent. I wouldn’t purchase this foundation if you do not like it oxidizing or if you want a really full coverage. But for me this foundation was a good purchase as it is under £10.
