Hi Deborah-Jane
Two words…Colour Striping. It is the most vital element when choosing a foundation. Start off by choosing three foundation colours that are closest to your skin tone, apply a stripe of each colour vertically on your lower cheek area. Thereafter determine which one matches your skin tone. Wipe the other two away, blend the correct one in and there you have it. Always remember to determine whether you have a pink skin tone or a yellow one – there’s nothing worse than getting the two mixed up.
If all else fails go into your local cosmetics store and have one of the beauty advisors assist you.
Have fun
