Skin colour is mainly determined by genetics, and it is neither possible nor safe to permanently change your natural complexion with a cream. What you can do is improve your skin health and make your face look brighter and more even-toned over time. A good daily skincare routine is more important than fairness creams. Use a gentle face cleanser twice a day to remove dirt and oil. Apply a light moisturiser suitable for your skin type to keep the skin healthy. Most importantly, use sunscreen every morning with SPF 30 or higher, even when indoors near windows. Sun exposure is the main reason for darkening and uneven skin tone. You may also use creams containing ingredients such as vitamin C or niacinamide, which can help reduce dullness and pigmentation safely. Avoid fairness creams that contain strong bleaching agents or steroids, as they can damage the skin and cause long-term problems. If you have persistent dark patches or uneven colour, it is best to consult a dermatologist for proper evaluation and treatment.
