Primary prevention
Primary prevention aims to reduce the
risk factors before a disease or
condition occurs. Primary prevention
method involves mainly sun
protection that comes in many forms
like sun avoidance, protective clothing,
and sunscreens.
The UV exposure would be the
strongest between 10am and 4pm
and sun avoidance between this
period of time is highly encouraged. If
one cannot avoid exposure to the
sun, clothing, hats and sunglasses that
protects one from sun exposure
should be fully utilized. Wide
spectrum sun screens that have a sun
protection factor (SPF) of at least 30
should be used when one gets
frequent sun exposure.
Secondary protection
Secondary protection refers to early
detection of disease, potentially while
still asymptomatic, to allow positive
interference to prevent, delay or
attenuate the symptomatic clinical
condition. This includes the following:
Retinoids e.g. Tretinoin
Antioxidants e.g. topical vitamin C,
oral supplements, CoQ10, Lipoic
acid
Estrogens
Growth factors and cytokines.
Tertiary prevention
Lastly, tertiary prevention is the
treatment of an existing symptomatic
disease process to ameliorate its
effects or delay its progress. Such
tertiary prevention includes the use of
chemical peels, resurfacing
techniques like micro-dermabrasion,
the use of ablative and non-ablative
laser systems, radiofrequency
technology, the use of exotoxin
Botulinum toxins and soft tissue
augmentation, also known as fillers.
