التحكم في الزيت واللمعان

Heat, or a routine that's too stripping, or both. Egyptian summer genuinely increases sebum production; so does washing with something harsh twice a day.

It's fine and it doesn't cause more oil — that's a myth. Blot rather than wipe, so you're not dragging.

Not the alcohol-based kind, no. A hydrating or BHA toner has a purpose; an astringent "for oily skin" mostly causes the rebound this page is about.

Very common. Oil and water are different things. Shiny by afternoon but tight after cleansing is exactly that combination, and it needs hydration, not more cleansing.

There's something to it — more sebum means better surface hydration and fine lines often show later. Not a reason to skip sunscreen, but a small consolation.
