The skin on the chest is vulnerable to the same effects of aging that cause facial wrinkles. As the production of elastin, collagen and hyaluronic acid decreases over time, chest wrinkles and creases can form.
Sun damage is another common cause of chest wrinkles because the chest, along with the face, is an area that is often exposed to harmful UV rays. Another cause, which is unique to chest wrinkles, is sleeping on one’s side. Women who sleep on their side are more likely to get chest wrinkles, because sleeping in that position creates an unnatural crease in the skin. Over time that crease can become permanent—similar to how dynamic facial wrinkles become static over time.
Chest wrinkles appear in a few different ways.
The signs of chest wrinkles
V-shaped wrinkles can form, beginning at both sides of the neck and meeting towards the chest. These wrinkles develop later and are typically deep in nature.
Between the breasts
This area begins with fine lines and over time can be a problem area for deeper wrinkles and creases as well.
