What should I do about dull and yellowish skin on the T-zone?

To address dullness and yellowish tone in the T-zone, consider the following measures for improvement: 1. The T-zone tends to produce excess oil, so use a gentle cleanser with appropriate oil-removing properties to ensure thorough cleansing. After washing, apply a brightening toner to the T-zone daily to provide hydration and control oil production. 2. Exfoliate the T-zone more frequently than other facial areas—recommended once a week—to remove accumulated dead skin cells and promote smoother, finer skin texture. 3. When applying moisturizer, do not neglect the T-zone; ensure it is adequately hydrated. Additionally, always apply sunscreen to the T-zone to prevent UV-induced pigmentation. 4. Adjust your diet by increasing intake of vitamin C-rich foods. Maintain a regular sleep schedule and avoid staying up late, which helps support skin recovery and overall skin health.
