Never smile while you are applying blusher, this will add years to your appearance.

So many people do this but when you smile tiny crinkles appear in the skin of your face, whatever your age, and the colour cannot penetrate fully into them. So when you relax your face you are left with lines that look like wrinkles!

Not a good idea at all. Keep your face nice and relaxed when you apply any kind of colour to your skin.
