Making the most of your make-up: foundation

Start mixing different combinations of the foundations, making a note of each one. Try to be precise - that is, if you have used one spoon of shade A to two spoons of shade B, note this down exactly. When you have three or four mixes, put them on your cheek/jawline area in thick strips with a lip brush in good light. Critically assess which foundation is the best.

If the foundations do not match your skin, try blending again, until you reach your perfect combination. Make a note of the exact combination and blend them in exactly the same proportions to make a full size bottle. There you have it, the perfect foundation for your skin colouring!
