Neck wrinkles develop as part of the natural ageing process, although the neck often begins to show signs of ageing earlier than other areas because the skin is relatively thin and delicate.
Several factors can contribute:
Natural ageing
Collagen and elastin production reduces over time, causing the skin to become thinner, less firm and more prone to fine lines and crepiness.
Skin quality
The neck has fewer sebaceous glands than many areas of the face, which can contribute to dryness and make changes in skin texture more noticeable.
Sun exposure
Repeated UV exposure damages collagen and elastin and contributes to pigmentation, fine lines and premature skin ageing. Protecting the neck and décolletage with daily SPF is therefore just as important as protecting the face.
Repeated movement
Looking down and repeatedly moving the neck can contribute to horizontal neck lines becoming increasingly visible over time.
Platysma muscle activity
The platysma is a broad superficial muscle extending across the neck. As we age, its vertical bands can become increasingly visible, contributing to lines, pulling and loss of definition around the neck and jawline.
Changes beneath the skin
Loss of structural support, changes in fat distribution and increasing skin laxity can all alter the contour of the neck.
Understanding which of these factors is most important is key to choosing the right treatment.
