Detailed answer

To improve uneven skin tone on your back and buttocks, exfoliation is key. Use a gentle scrub or exfoliating brush to remove dead skin cells and promote cell turnover. Incorporate skin brightening products containing ingredients like alpha hydroxy acids, kojic acid, or vitamin C. These ingredients can help to fade dark spots and even out the skin tone. Also, make sure to protect your skin from sun damage by using sunscreen, as excessive sun exposure can worsen uneven skin tone. Consistency is important, so make exfoliation and using skin brightening products a regular part of your skincare routine. Additionally, maintaining a healthy lifestyle with proper hydration, a balanced diet, and exercise can also contribute to an improved skin tone.
