Radiations Of The Sun
The sun emits three form
of radiation infrared, visible and ultraviolet. Infra red and
visible light are valuable because they provide warmth and the
ability to see. Ultraviolet rays can be harmful depending on
their wave-lenght:- UVA (longest), UVB (middle length) and
(shortest). Each one them penetrates the atmosphere and affects
our health in different ways.
These rays are absorbed into the epidermis and can cause skin
cancer by altering the normally well-organized behavior of
cells. By breaking down the collagen and elastin building blocks
they can create , by further causing wrinkles, clumping up the
protein, weakening the walls of small blood vessels and spider
rays can be as harmful as UVB rays. UVA is absorbed into the
epidermis and pass through the dermis. They remain in high
intensity all day long and not just peak hours of 10 a.m. to 2
unlike the UVB rays.
UVB and UVA rays can both
damage the protecting covering of eyes known as Cornea. The
resulting damage to the lens and the retina may cause cataract
and visual acuity problems.
The sun also affects the
immune system UVB and particularly the UVA rays can damage the
langerhans cells, which are important component of immune system
within the skin. UV rays can damage the WBC (White
as well, rendering them important in face of the enemy. In
addition damage to the langerhans cells and WBC can reduce the
effectiveness of the immune system leading to vulnerability of
the skin to viruses and other diseases.
rays are absorbed in the ozone layer and if small amounts of
these rays succeed in passing through, they are absorbed in the
epidermis of the skin.
With a Sunscreen
Sunscreens are available
in the market in the form of creams, gels, lotions, sprays and
ointments. They contain various agents which have been proven to
protect the skin against the rays of the sun.
Para-amino-benzoic acid or
PABA, PABA esters (glycerol, padimate A, padimate O, or octyl
dimenthyl PABA) and cinnamates are agents which are effective in
protecting the skin against UVB rays. Benzophenones (oxybenzone,
methoxybenzone and sulfisobenzone) and Parsol are effective in
protecting against UVA rays.
To totally protect your
skin, select a sunscreen with a combination of two of these
agents, one of UVA rays and one of UVB. Take the help of a
dermatologist to chose a product that suits your skin type.
Also, at the same time pass a test on hand before applying it on
Some factors need to be
considered while choosing a sunscreen:
Does it protect my
skin or do I have signs of sun exposure?
Is it too occlusive
Do I break on pimples
when I use it?
Do I break out a rash?
Depending on these
factors you can pick a sunscreen from the options available :
If you have a dry skin
avoid using tretinoin (Retin-A, Stieva-A, Retisol-A, Refuva-A,
Renova, Vit A Acid) which tends to dry the skin, a cream
base can be a better choice e.g. Ombrella 15 or Photoplex).
Retisol-A is particularly good because it combines a
broad-base sunscreen with tretinoin and a moisturizer in a

sunscreen varies with the
skin type, your daily activities,
geographical locations and climatic condition. As UV rays
are reflected from sand, sun, water, snow and ice. The
frequency of application of a sunscreen, too will vary with
your activities. If you work out-of doors, whether in winter
or summer, several applications of high SPF sunscreens
throughout the day will be required.
