For an effective oily skin routine, the goal is to control shine and prevent clogged pores without stripping the skin. Start with a gentle, foaming or gel-based cleanser containing salicylic acid to remove excess sebum twice daily. Follow with a lightweight, oil-free, non-comedogenic moisturizer—skipping this step can actually trigger more oil production. Finally, always apply a mattifying or oil-control sunscreen in the morning. Once or twice a week, incorporate a clay mask or a chemical exfoliant (like niacinamide or further salicylic acid) to deeply unclog pores, but avoid harsh physical scrubs that can irritate and worsen oiliness.
