Neck laxity is the result of loss of skin thickness and elasticity with age and is accentuated by the downward pull of the superficial neck muscles, leading to sagging and horizontal wrinkles.

Excess of submental fat contributes to loss in definition of jawline, especially in profile, and in sagging skin.

The neck is a difficult area to treat, as it is more delicate and thinner compared to
facial skin. Neck skin treatment is important, as is treatment of décolletage and hands. It avoids unbalance and betrayal of age when compared with (treated) facial skin.
