11 Oily Skin Care Tips That Control Excess Oil

9. Mind diet and hydration to manage sebum production

What you eat and drink can influence sebum activity, though topical care usually has a bigger immediate impact. Some studies link high-glycemic foods to increased sebum production, so reducing sugary snacks and refined carbs may help over time. Prioritize whole foods, balanced meals, and steady hydration to support overall skin health. Dairy effects vary by individual; pay attention to how your skin reacts rather than following broad rules. Staying well hydrated helps the skin's cells function, but hydration alone won’t prevent oiliness. Treat diet changes as complementary to your topical routine. If you suspect a food factor is driving breakouts, try a short elimination with notes on skin changes, and consult a healthcare provider for personalized advice. Small, sustainable food swaps often work better than strict diets.
