would like to ask ..

i have a very oily face but no pimples la ... As i aged, i notice that the skin of my face is getting thicker and rougher and i see some women on the street haf very smooth and thin skin .. very nice.

So, wanna ask .. if i get a cleanser, toner, and clay mask from face skin shop, roughly how much do i need to prepare ?? Are they expensive ??

Or any other recommendations ??
