I love the chambor primer it is the best primer for oily skin types .Its silicon based formula just gets absorbed into the skin, just a pie size is enough will go long way.
It is very light will keep your face matte/oil free for atleast 4-5 hrs .Its my go to product .Does not make your skin feel heavy .As you apply on face will need to work fast as it gets absorbed very quickly. I suggest oily skin types must give a try once.
