Why Neck and Chest Lines Happen
The skin of the neck and chest is thinner and more delicate than many other areas of the body. It is also exposed to years of sun, movement, sleep compression, and environmental stress. Over time, collagen and elastin decline, the skin becomes less resilient, and horizontal neck lines, vertical chest creases, and crepey texture may become more visible. Common causes of neck and chest aging include:
- Loss of collagen and elastin
- Skin laxity
- Sun damage
- Crepey skin texture
- Repetitive neck movement
- Sleep lines on the chest
- Posture and “tech neck”
- Hormonal changes that affect skin quality
- Thinning skin
- Loss of deeper structural support
Because these concerns are usually related to skin quality and support, filler alone may not create the improvement patients are hoping for.
