The Comparison and Contraction Between Various Skin Cells

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

Human beings are no exception to biological evolution. Like other organisms around the world, humans have significantly changed overtime and have developed all sorts of diverse characteristics. One noticeable characteristic of human beings is the variation of skin

Skin aging is a process that naturally occurs in human beings from birth and is different in each person due to intrinsic and extrinsic factors. To find out what has the most influence on the human skin, both factors need to be fully researched. You can also look at other details to do with skin aging like the process of it, the appearance of it and how it can be prevented. Both factors will be covered as both are completely different processes of the skin aging. It would be true to say that not all 70 year old females have the same skin, as many factors will affect how the skin of a 70 year old could look.

In today's world, there is a large amount of emphasis on physical beauty, youth, and how to stay younger for longer. Although many have condemned this as a particularly shallow approach to life, there is also an underlying concern for physical health, which is at the bottom of longevity and a concomitant better-looking physique. Indeed, the longer a person can maintain a healthy lifestyle and a focus on self-care, the longer he or she tends to maintain a relatively youthful or at least healthy demeanor. This has also become a growing concern as life expectancy has increased almost exponentially for human beings over the last century. For this reason, companies such as Dr. Perricone MD Skincare continue to do extensive research to determine ways in which the longevity and youth of the skin can be prolonged and even restored.

Also, three primary structural components of the dermis, collagen, elastin and GAGs have been the subjects of the majority of anti-aging research and efforts for aesthetic-anti-aging strategies pertaining to the skin, from “anti-wrinkle creams” to various filling agents.

The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for

premature aging of the skin, and skin cancer. Therefore, while this article was useful for

In this paper there are three main topics that are going to be covered. They are alternatives to animal testing, animal testing in cosmetics, and the news in the cosmetic industry related to animal testing. For this paper there were four sources that were evaluated. All of them had a few things in common and through that it was easy to link them together through three different subtopics that will be evaluated later in this paper. The first source that I will be using is “The Science of Dermocosmetics and Its Role in Dermatology”. This article was written by Dreno, B., E. Araviiskaia, E. Berardesca, T. Bieber, J. Hawk, M. Sanchez- Viera, and P. Wolkenstein. The second article that will be effective in this essay is “New

Name two organelle’s found in the animal cell that could not be seen in your cheek cells.

Picture being locked up in a cage, injured, alone, and in pain. Imagine being a prisoner without committing a crime. This scenario exposes the life of rabbits, mice, dogs, pigs, cats, and many other animals used in cosmetic product testing. The topic of whether animal cosmetic testing is necessary or not has been a topic that many have put-off, but something that should be thought about. The reason that specific animals like, rabbits, chimpanzees, and apes are used for experimenting is because their DNA almost exactly matches a human’s. Since these mammals’ DNA is almost identical, researchers are positive that they are a great tool for testing cleaning and cosmetic products. Though researchers don’t feel any remorse for how they treat

In order to better understand aging-associated diseases, it is first necessary to define what aging is. Aging is a complex, multifactorial process of harmful mutations in cells and tissues that are accumulated over time and result in an increased risk of disease and, eventually, death (Tosato, Zamboni, Ferrini, & Cesari, 2007, p. 401). Contrary to the belief that aging can be cured through medical advances, it is scientifically accepted that, while human life expectancy has increased, the human life span has remained largely unchanged for the past 100,000 years (Tosato et al., p. 401). Therefore, future developments in aging research ought to focus on addressing treatment and prevention of major aging-associated diseases that will

At 2 weeks, Melanie’s cells first started the miraculous transformation process of changing into the specialized cells that form all the parts of her body. At magnificent speed, cells begin to migrate forming three layers. Each of the layers are assigned to build something, the top layer are the cells that make skin, hair, teeth, and brain. When the cells in Melanie’s surface

Premature aging is one main effect of sun exposure. Becoming an old looking, wrinkly person is the last thing people look forward to, but did you know that the average
