How can skin become whiter over time?

To gradually achieve fairer skin, you can take the following steps:

1. Keep your skin clean daily, exfoliate regularly, and use whitening and moisturizing products.

2. Ultraviolet radiation is a primary cause of skin darkening, so apply sunscreen when going outdoors and avoid going out during peak sunlight hours.

3. Increase intake of foods rich in vitamins C and E, such as citrus fruits, kiwis, and nuts, which help inhibit melanin production.

4. Consider professional treatments like chemical peels or laser skin lightening, but only under the guidance of a qualified dermatologist.

5. Maintain a healthy sleep schedule, avoid staying up late, and ensure sufficient sleep to support skin metabolism and repair.
