Ultraviolet

The multi-purpose is an all around disinfectant, the Hydrogen Peroxide is a disinfection make to clean, rinse, disinfect, and store properly, next the Ultraviolet Light Disinfection is a system that uses subsonic vibration along with short wavelength ultraviolet radiation to clean and disinfect soft contact lenses. The Enzymatic Cleaners is an enzyme that removes the accumulation of tear proteins of the lens surface. Lastly, the In-eye cleanser and it is…

Melanocytes are pigmented cells (called melanin) in the epidermis. There are many longitudinal tassels reaching the top cell layer of the epidermis to bring the melanin bags up here. Melanin plays a role in protecting the skin from the effects of ultraviolet radiation, which is why, after sun exposure, your skin will become darker, whites are less likely to have melanin bags when exposed to sunlight. Only sunburn, not black, and if exposed to the sun for long without the protection of…

Melanoma is a cancer that develops in the pigment cells of the skin called melanocytes. It is a type of skin cancer that can be more serious than any other forms because it has the ability to metastasize, which is the development of secondary malignant growths from the primary site of cancer, to other parts of the body and cause serious illness or even death. Melanoma most often occurs when something goes awry in the melanin-producing cells or as already mentioned, melanocytes, which give…

How does the sun harm us? : Skin exposure to UV light causes sunburn. Abigail Pereira The Sun is the center of the universe. Sunlight is essential to all living organisms on the earth. However excess exposure to the sun may causes immense damage to living organisms as follows. Skin cancer (1) is caused due to mutations in the DNA of our skin cells. These mutations cause the cells to create big cancer cells in the body. Most of the damage caused to your DNA cells are mostly due to UV rays. The…

Aging is an inevitable process undoubtedly, but with essential vitamins and supplements included in the diet, its adverse effects can be prevented or delayed. In order to feel younger…

Sunlight is the main source of UV rays. UVA rays age skin cells and can damage their DNA resulting in wrinkles, and play a role in some skin cancers. Most tanning beds give off large amounts of UVA, increasing risk of skin cancer. UVB rays have a little more energy than UVA rays and directly damage skin cells’ DNA. They are also thought to cause most sunburns and skin cancers. UVC rays have the most energy, butbut they get trapped in our atmosphere. They do not usually cause skin cancer.…

Extra Virgin Olive Oil Impairs UV-Induced Cell Damage in Cancer-Prone Mice INTRODUCTION Ultraviolet radiation produces various wavelengths that are part of the electromagnetic spectrum. The four different UV wavelengths are classified as UVA, UVB, and UVC. UVA produces the longest wavelength at 320-400nm, UVB produces wavelengths from 290-320nm, and UVC wavelengths are the shortest wavelength that is completely absorbed by the ozone layer. However, it is known that…

melanin in our skin the darker our skin colour is. Homo sapiens originally had a white-pink skin colour and they were covered in hair. Over time we grew less and less hair on our bodies resulting in less protection from the sun and its harmful ultraviolet (UV) radiation. In the very northern or southern countries, areas further away from the equator, there is less exposure to UV radiation due to its position. This resulted in people having lighter skin and due to these areas being colder people…
