Sunscreen - Wear the right sunscreen like natural and bio-degradable sunscreen
The sun is so necessary to life and yet, it is the skin's greatest
enemy. Exposure to the sun's rays is the most important factor in the
ageing of the skin. Every time we expose the skin to the sun, some
degenerative damage takes place.
As exposure to sunlight produces free radicals, a new trend in
sun-protection products is to include Vitamins E and/or C. Ultraviolet
light, smoking and other forms of pollution produce an inflammatory
reaction in the cells. New skincare products, which contain
anti-inflammatory ingredients, help prevent damage.
Ultravoilet Radiation and Sunscreen
We all know by now that it is the sun's ultraviolet rays that are
harmful to the skin. There are many kinds of ultraviolet rays,
depending on wavelengths. The UVA and UVB rays are damaging to the
skin. The UVA rays have a longer wave-length and do not bum the skin.
They, however, penetrate the skin and affect the dermis by causing
damage to collagen and elastin, the supportive tissues of the skin.
Damage to these lead to the manifestation of the signs that we
associate with ageing, like sagging skin, lines and wrinkles.
Exposure to ultraviolet rays also increases the production of
melanin, causing the skin to darken. Sun-exposure, in fact, contributes
to the development of hyper pigmented skin problems. It is also
responsible for allergies and dehydrated skin, even leading to a skin
that is fragile and sensitive. Wrinkles, dryness, loss of firmness, and
an uneven color tone are all part of what we call sun damage. Both UVA
and UVB rays also contribute to the development of skin cancer.
Another cause for alarm is the damage that is being caused to the
ozone layer by man-made chemicals, like chlorofluorocarbons. We are
gradually being exposed to greater risk, because the ozone layer
filters the most damaging part of ultraviolet radiation. Damage to the
ozone layer ultraviolet means greater damage to the skin.
How Sunscreen products works?
Sunscreen works by combining organic and inorganic active
ingredients. Inorganic ingredients like zinc oxide or titanium oxide
reflect or scatter ultraviolet (UV) radiation. Organic ingredients like
octyl methoxycinnamate (OMC) or oxybenzone absorb UV radiation,
dissipating it as heat. Some sunscreens protect us from the two types
of damaging UV radiation: UV-A and UV-B. Both UV-A and UV-B cause
sunburns and damaging effects such as skin cancer.
Tips while going for sunscreen
When purchasing sunscreen, the Sun Protection Factor or SPF measures
how effectively the sunscreen formula limits skin exposure to UV-B rays
that burn the skin. The higher the SPF the more protection the
sunscreen will provide against UV-B rays. SPF does not measure UV-A. If
you are looking for UV-A protection, the experts recommend that you
purchase a product that has broad-spectrum protection.
Benefits of Sunscreen
Sunscreen: you slather it on before you go to the beach. It keeps
you from being fried to a crisp. It helps prevent your skin from
getting that wrinkled, leathery look. And it protects you from the
ultraviolet rays that cause skin cancer. Sunburn, caused by a type of
ultraviolet (UV) light known as UVB, has served as a surrogate for far
more serious conditions like melanoma and basal and squamous cell
carcinoma, three forms of skin cancer.
