When it comes to makeup and skincare, we're all guilty of committing a couple of beauty sins.
But when Women's Health asked professional makeup artists what they thought were the ultimate makeup mistakes, this super common one was among them.
Celebrity makeup artist, Matin Maulawizda, said that one of the biggest beauty blunders we can make is not prepping our lips for matte lip products.
Yep, I'm sure most of us are guilty of doing this at least once.
Maulawizda said: "Using matte heavily pigmented lipsticks before properly prepping the lips is one of the worst makeup mistakes."
"Not only does it make your lips dry, but they also look awful as the day progresses. I recommend prepping the lips before color."
He recommends using a lip scrub followed by a moisturising lip balm to prepare your lips before applying any product.
