Detailed answer

Night creams typically contain ingredients that can help with dark spots and uneven skin tone. However, it's important to note that the effectiveness of night creams in lightening dark knees may vary from person to person. The skin on the knees is generally thicker and darker due to factors like friction and accumulation of dead skin cells. While night creams may provide some hydration and mild brightening effects, they may not entirely eliminate dark knees. It is recommended to combine night creams with other treatments like exfoliation and regular moisturization to improve the appearance of dark knees. Additionally, maintaining a consistent skincare routine and protecting the knees from excessive friction can also contribute to achieving more even skin tone.
