Take a look at how smooth your skin is. Looking at my skin, it is difficult to believe that I, Alexandra Henry, will have saggy, wrinkly, and dry skin in years to come. Reading about the skin changes as people, women in particular, age made me understand the way skin deteriorates.
In class, I was stunned when I learned that the skin is the largest organ of the human body. I guess, it is because when I think of organs I think of kidneys and all the complexity of the insides of the body. I gained a greater understanding of the layers of the skin: epidermis, and dermis. Each of these layers has a unique job that plays key roles in our biological lives. The epidermis is the outer-most layer, and it contains corneum (dead cells), lucidum (clear layer), granulosum (small particles), spinosum (spines), and basale (contains stem cells, melanocytes, langerhan cells, and merkel cells). The dermis, located underneath the epidermis, is comprised of blood vessels, lymphatic vessels, nerves, sweat glands, and sebaceous glands (maintains the epidermis’ flexibility). Receptors are situated on the dermis, so we are able to respond to environmental stimuli.
Premature skin aging can be the outcome of an extensive amount of physical and psychological stress, unhealthy nutrition, alcohol consumption, overindulging, pollution from the environment, and exposure to UV rays (Skin Aging). To my surprise, hormones are also a contributing factor to skin aging. Sex hormones function in maintaining the skin the way it is. Is that the reason as people go through puberty, it is likely to see pimples scattered all over a pre-teen? Yes, it is. Raging hormones entail skin acne, so low levels of hormones result in the skin aging and losing its intactness. Women are faced with the hormonal change of estrogen in menopause, and, believe it or not, it’s a factor in the wrinkles and other aspects of aging skin. Epidermal and dermal layers of the skin become thin; therefore it deteriorates and becomes saggy.
