Whenever I use make up it just stays for maximum 2 hours and after that it makes my face look ugly and oily. I have tried using the most expensive and quality products but the situation is still same. I am really fed up as I donât know what to do after spending lots of money on my make up products? Then one day I asked my friend and she suggested me to use make up primer? She said that it will help my make up to stay for long and keep it dry and beautiful. I want to know is it true and can you tell me how this make up primer works?
