What should be in a toner for oily skin?

A toner for oily skin should comprise ingredients that balance oil production without stripping the skin of its natural moisture. Look for components such as Salicylic Acid, a BHA that deeply penetrates the skin, unclogging pores, and eliminating excess oil. Witch Hazel, a natural astringent, also helps reduce oil and minimizes pore size. Other elements like Niacinamide and Green Tea Extract help control oil production while soothing the skin. Always avoid alcohol-based toners, as they can be excessively drying, leading to an overproduction of oil.
