I bought this mac lipstick today, ending the search for a nice vibrant pink. The mac lady told me its got blue undertones to make your teeth look whiter. I cant comment on this as I am halfway through using some crest whitening strips and my teeth are in so much pain (no pain no gain?)
I used to have major problems with wearing bright lipsticks as within a couple of hours they were faded and looked horrible on my lips. However I bought some 'Lipcote' from superdrug for about £3 and I brush this on after applying lipstick and it seals it making sure it doesn't budge even after eating, perfect!
Hope your having a good Sunday,
