Dark circles under the eyes are a common concern, often attributed to insufficient sleep or allergies. However, they can also be genetic, resulting from thin skin that allows muscle visibility. Treatments aim to address this by thickening the skin through collagen stimulation. Procedures include laser treatments, which build collagen, and the use of exosomes or platelet-rich plasma. These methods work to subtly increase skin thickness, which helps diminish the appearance of dark circles.
