How do you manage oily skin in the summer?

Maybe it's because the weather is gradually getting warmer, but I've noticed a lot of oiliness coming up by the time I wake up in the morning or around the afternoon...

I heard about something called Lara Peel at the dermatology clinic; has anyone tried it?

How do people with oily or combination skin manage pores and oiliness in their T-zone and butterfly zone?
