Detailed answer

Improving uneven skin tone is a gradual process and the timeframe may vary depending on individual skin conditions. Generally, it can take anywhere from several weeks to a few months to see noticeable improvement. This is because the process of lightening dark spots or hyperpigmentation requires time for the skin to regenerate and for new, healthy skin cells to replace the discolored ones. Consistent use of targeted skincare products such as brightening serums, exfoliants, and sunscreen can help accelerate the process. It's important to be patient and maintain a regular skincare routine to achieve the desired results.
