Dark eye bags, also known as dark circles, are caused by a variety of factors, including genetics, aging, and lifestyle habits. Thin skin under the eyes allows blood vessels to show through, leading to a bluish or purplish tint. As we age, skin loses collagen and elasticity, making the blood vessels more prominent. Lack of sleep, stress, and fatigue can worsen the appearance by causing fluid retention and dilated blood vessels.

Sagging skin is primarily caused by the natural aging process, as the production of collagen and elastin—proteins that provide skin with firmness and elasticity—declines over time. This loss leads to skin loosening and sagging. Sun exposure accelerates this process, causing photoaging and further weakening of the skin’s support structure. Other factors, such as smoking, dehydration, poor diet, and a lack of sleep, can also contribute by damaging the skin’s ability to regenerate and maintain moisture.

Poor jawline definition can result from a combination of factors such as genetics, aging, and lifestyle choices. As we age, the skin loses collagen and elastin, causing it to sag, which can blur the contours of the jawline. Loss of facial fat, particularly in the lower face, can also lead to a less defined jaw. Excess fat accumulation under the chin, commonly referred to as a “double chin,” can obscure the jawline.

Lines and wrinkles are primarily caused by the natural aging process, as skin loses collagen, elastin, and hyaluronic acid, which are essential for maintaining firmness and elasticity. Sun exposure accelerates this breakdown, leading to photoaging and the development of fine lines, particularly around the eyes and mouth. Repeated facial expressions, such as smiling or frowning, cause dynamic wrinkles that deepen over time. Smoking, poor diet, and dehydration also contribute by reducing skin’s ability to regenerate and maintain moisture.
