I like to think that I'm immune to the sales pressure of the MAC artists, but my ownership of Prep + Prime Lip proves the contrary. I was at the counter purchasing a couple lippies when the artist asked me about Prep + Prime Lip. She then looked at me aghast when I told her that I don't use a primer when I wear dark lipstick. Long story short... I bought it.
"A colour-free base to wear under lipstick. Adds light moisture, smoothes and refines the lips. Improves the appearance of applied lip products."
When applied MAC Prep + Prime Lip feels very similar to a lip balm. I like to let it sit on the lips for about two minutes before I apply lipstick on top. Overall I am very pleased with the purchase and it does what it says it does! I really like how smooth the lipsticks apply and how moisturized my lips feel underneath. I think this product is great for someone that wears bright/dark lips frequently or suffers from dry lips. I don't think this primer extends the wear time, but it definitely makes wearing lipsticks much more comfortable.
I highly recommend this product and will definitely be repurchasing when I'm finished with this one!
I feel like there are primers for just about everything these days... do you think they are necessary?
Do you use a lip primer?
