Stop doing this when you apply lipstick
It's worth a try.
Recently, when in Toronto with Marc Jacobs Beauty, Vanngo asked model Hannah Donker to “pop” her lips together, rather than rub them together, to blend her lipstick.
“I don’t like when you smush them together, you get this line here,” explains Vanngo, pointing to the Cupid’s Bow. “Doing the ‘pop-pop’ blends the lipstick together, [without getting the line.]” (See the move in action below.)
Sir John told us he uses the same smacking motion to achieve his signature “PB & J” (as in, yes, peanut butter and jelly) ombré-looking lip.
Beauty lesson learned.
