Transcript of timeline of tanning

timeline of tanning! by: Alex Norton date: before 1920's "among aristocracy it was considered vulgarly and indecent to have
swarthy skin or skin with freckles".
- fashionable tendencies of last century: pale skin fashion Pale skin was in fashion
...a very long time ago. Pale skin was for those who had money - and did not get a sun burn from
being outside working in the fields all day long.
Therefore: people strived to have a pale skin tone. This was taken to extreme measures to ensure that china-doll look innocent measures taken: dandelion juice & lemon juice were both used to "lighten" the skin tone. These items both contain acids and alkaloids - ingredients which
remove the top layer of dead cells of the epidermis, while bleaching skin for the moment. Extreme Measures Taken: & Arsenic Mercury ...were also chemicals individuals used to make their skin pale. Both of these lead to
liver damage and pathological changes in the workings of the nephros. Date: 1920's 'The roaring twenties' In 1923 french designer
Coco Chanel (designed
the brand Chanel) was
spotted leaving a
nobleman's yacht with a
deep tan after cruising
from Paris to Cannes.
After getting of the boat
she later claimed to
have stayed out in the
sun too long, but her
new sun tan set a fashion
trend. & Not long after this, magazine articles began promoting tan skin. The number of articles encouraging pale/ bleached skin decreased It also became popular and fashionable to spend the
holidays at the beach or in warm tropic climates, which
also gave people suntans. Date: the 1950's "It was an itsy, bitsy, teenie, weenie, yellow polka-dot bikini
That she wore for the first time today
An itsy, bitsy, teentie, weenie, yellow polka-dot bikini
So in the locker she wanted to stay
Two, three, four, stick around we'll tell you more"
- Brian Hyland That's right,
It's the bikini!!! Bikinis were first seen in the 1950's and
made a splash with tanning...
people were now able to tan all over
instead of just face and legs. This is also the time period when browning creams
and dyes (self tanners) became available.

Promos claimed things such as the creams would
"patch up tans" and help maintain the tan for as
long as possible. Date: 1972 sunscreen was made available in the 1960's, but it wasn't until 1972 that the labeling
of SPF (sun protection factor) appeared on bottles. Date: 1980's When you are in water, you tan faster. This is because the sun reflects off the water and onto your skin, bringing you more UV rays than you would get on land. which leads to... BABY OIL! people discovered that baby oil did the same thing to your skin as when you are in water.

It gives the skin shine, and refelcts the sun much faster than it would if nothing was applied. Date: 1980 - 1990's People’s schedules started to become chaotic. Women were now working full time, caring for kids and still arriving home to make dinner at five. So outdoor tanning time became very limited. This is when tanning studios and salons began to appear. The indoor tanning bed was invented. This quickly became popular because individuals only had to spend a few minutes inside a tanning bed and they could establish the tan they worked so hard to maintain all during the summer. WHY??? Tanning beds were developed as part of a medical research many years ago. They was used to help patients with diseases like rickets, to develop more calcium and stronger bones. Rickets is a childhood condition caused by serious vitamin D deficiency. This lacking in vitamin D results in weak, soft bones, along with slowed growth and skeletal development. This disorder begins in childhood and if it occurs later in life is known as osteomalacia. BY WHO??? In the early 1970’s a German scientist, Friedrich Wolff, used artificially produced indoor tanning light to study athletes and how they may or may not benefit from more exposure to sunlight. During his studies, he also noticed how the athletes were also developing darker more golden skin tones. At this point in time, tanning was very fashionable, so Wolff used his knowledge to create the first indoor tanning beds.

Date: 1960's Sunless tanning (also known as self tanning, fake tanning, or UV-free tanning) came about in the 1960's due to the discovery of the links between sun exposure and skin cancer.
Spray on tanning refers to applying chemicals to the body to produce an effect similar in appearance to a suntan. SO..What is a 'sun tan' exactly?!? “UVB ultraviolet rays are much shorter at only 290 –320 nanometers". (Valesko, 2006)
"These rays are the ones that cause sunburns and are considered the main cause of skin cancers”. (Valesko, 2006). The sun emits two different types of ultraviolet rays. UVA UVB & UVA “UVA rays are long solar rays of about 320 – 400 nanometers. These rays can go through windows and clothing. Basically, when you are outside, you are being hit by UVA rays”. (Valesko, 2006).
These are also the light rays responsible for aging (wrinkling/leathering of the skin) because they penetrate the skin deeply.
They are also less likely to give you sunburn. Studies have also shown that UVA rays exacerbate UVB's carcinogenic effects but may also directly induce some skin cancers, including melanomas. VS. UVB skin cancers a The most serious kind of skin cancer because it “may spread quickly from the skin through the lymph nodes or blood, to internal organs.” (What Are The Different Types Of Skin Cancer?).

There are 3.5 million cases in two million people, diagnosed annually with skin cancer.

Skin cancer is the most common form of cancer within the United States.

Coincidence with our obsession with tanning? It’s a good possibility. There are a number of different types of skin cancers, the type of cancer it is depends upon the type of skin cell from which it arises. Basal cell carcinoma is a nonmelanome, which sets it apart from the more serious melanoma skin cancers.

Basal cell carcinoma is the most common form of skin cancer (more than 90% of all skin cancers are labeled as this one).

In addition, it is also one of the less serious forms of skin cancer. It grows slowly and rarely spreads. 1) BASAL CELL CARCINOMA 2) SQUAMOUS CELL CARCINOMA This is more serious because it spreads to vital organs inside the body.

Spreading occurs in a few cases in every 100. It does so slowly. “At first cancer cells tend to spread only as far as the nearest lymph nodes structures, which filter out and trap the cancer cells.

If spread has occurred, the affected lymph nodes can be removed before cancer spreads to vital organs.” (What Are The Different Types Of Skin Cancer?). 3) MALIGNANT MELANOMA
