Detailed answer

While collagen is an essential protein for maintaining skin health and elasticity, its effectiveness in directly improving dark circles and under-eye bags is limited. Dark circles and under-eye bags are often caused by various factors such as poor blood circulation, dehydration, lack of sleep, or genetic predisposition. Collagen supplements primarily work by supporting overall skin health, but may not specifically target these issues. It is important to focus on other remedies such as practicing good sleep habits, staying hydrated, using topical skincare products containing ingredients like caffeine or retinol, and implementing lifestyle changes to manage stress and promote healthy circulation for significant improvement in the appearance of dark circles and under-eye bags.
