Detailed answer

Although there is limited scientific evidence directly linking dark spots to excessive sugar intake, high sugar consumption can indirectly affect the skin's health. Elevated blood sugar levels can lead to glycation, a process where sugar molecules bind with proteins in the body, resulting in the formation of harmful substances called advanced glycation end products (AGEs). AGEs can negatively impact the skin's collagen and elastin, leading to uneven pigmentation and potentially contributing to the formation of dark spots. Additionally, a diet high in sugar can increase inflammation and elevate insulin levels, both of which may aggravate existing skin conditions such as acne or melasma, which can manifest as dark spots. However, it's important to note that dark spots can also be caused by other factors like sun exposure, hormonal changes, or skin injuries. Seeking advice from a dermatologist can help determine the exact cause of dark spots and develop an appropriate treatment plan.
