Worsened skin quality
Aging affects the skin quality as well, and thus, it leads to issues like crow’s feet and wrinkles. However, diabetes affects the skin as well and causes dark patches on the skin, especially on the knuckles, elbows, and back of the neck.
These changes are a result of a condition known as Acanthosis nigricans. High blood sugar causes the growth of skin cells and melanin. Yet, weight loss and topical use of effective ointments prescribed by an experienced dermatologist can help you alleviate these issues.
