Detailed answer

To brighten sallow skin, exfoliation is key. Regularly exfoliate your skin using gentle chemical exfoliants like alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) to remove dead skin cells and reveal a brighter complexion. Look for skincare products that contain brightening ingredients such as vitamin C, which helps in reducing dullness and promoting a more radiant skin tone. Niacinamide is also beneficial as it can help to even out the skin tone and improve overall brightness. Additionally, protecting your skin from sun damage by using SPF daily is crucial, as prolonged sun exposure can contribute to sallowness and uneven skin tone. Remember to maintain a healthy lifestyle by drinking plenty of water, eating a balanced diet, and getting enough sleep, as these factors can also impact the appearance of your skin.
