With aging of the skin, dermal cells become less active, producing less components. This means that the skin texture and appearance deteriorate. 

Sun exposure will worsen this process by inducing UV damage and skin of hands and décolletage are particularly prone to UV exposure.

Ageing on the hands and décolletage is characterized by sagging, thinning of the
skin, age spots (lentigines), wrinkling and general changes of skin texture.

In a global anti-ageing program the treatment of neck, décolletage and
hands treatment is important to create a balanced rejuvenated appearance
when compared with treated facial skin.
