Warts are skin growths
caused by the human papilloma virus (HPV). They are more common
in children and young adults but no age is spared.
Wrinkles, often equated
with ageing are of enormous concern in modern societies, especially
among women. They need to be differentiated from the fine lines
due to dryness of the skin which respond most readily to many
moisturisers. Sun-damage accelerates wrinkling which is why fair-skins
develop wrinkles earlier than the dark-skins.
- Wrinkles develop when
the collagen fibres in the dermis degenerate as a consequence
of intrinsic ageing and photoageing (see ageing).
Wrinkles may be divided into two types:
- Dynamic wrinkles which are caused by the action
of the muscles of facial expression on skin that has loss its
elasticity due to ageing.
- Static wrinkles.

- Minimise sun-damage
(see sun protection). Remember
that sun-damage begins as soon as you are exposed to the sun
so precautions should be taken from a very early age.
- Avoid smoking as nicotine
reduces blood circulation to the skin and may predispose to the
development of wrinkles.
What the doctor
- Prescribe topical
- Perform chemical
(surgical skin planing), laser
resurfacing, face lifts or use implants
(eg., collagen) to puff up wrinkles.
- Inject botulinum
toxin to weaken the muscles of facial expression that cause
