Maximizing Skin Health and Beauty: Exploring Skin Care Concerns

Skin health and beauty are prominent in today’s society, driving a multi-billion dollar industry. As a family physician, I’ve seen various skin issues, some stemming from diseases, lifestyle habits, and medical conditions. Understanding skin layers and cells is helpful. Excessive sun exposure can lead to photoaging and increase the risk of skin cancer, emphasizing the need for UV protection measures.

Skin health and beauty- big business

Browse social media or news sites online and you notice skin health and appearance is a priority for most people. Sales for skin care products and services is a multi-billion dollar industry. If you’re on social media, you’ve probably seen posts from friends who are involved in direct-selling companies for skin care, maybe you are also.

As a family physician, I treated skin problems frequently. Some of them were due to skin diseases, but some resulted from lifestyle habits, other medical conditions, and even medical treatments. While some of these may be unavoidable, others are preventable.

Skin Deep- cells and layers

First, let’s take a deeper look at our skin, it’s more complex than you may realize. It has two layers-

the top layer, the epidermis

the lower layer, the dermis

Skin disease and trauma involve damage to one or both layers of the skin- the dermis or epidermis, or to the individual cells- squamous cells, basal cells, or the melanocytes-the cells with pigment that give our skin color.

Cancers can develop in any cell of the skin. Melanoma is cancer of the melanocytes.

Ultraviolet light-an avoidable risk to skin health and appearance

Basking in sunlight may enhance your mood, but too much of it can damage your skin.

The signs of photo-aging are obvious to physicians-

  • yellowing of the skin complexion
  • dry and rough texture with wrinkling,
  • unevenly pigmented skin tone with dilated blood vessels.
  • stretched out
  • easy bruising

Photoaging

Photoaging is premature aging of the skin caused by repeated exposure to ultraviolet radiation (UV), primarily from the sun but also from artificial UV sources, such as tanning beds. Besides aging, excess sun exposure can cause

  • Burns
  • Rash due to increased sun sensitivity when taking certain medications
  • Cancers- skin cancers are the most common type of cancer.

Understanding COVID-19 vaccines in 25 minutes

Learn how vaccines are made and how they work. Review the concept of herd immunity and why it’s so important. Recognize the reasons behind vaccine hesitancy and why it matters and may enable the spread of disease.

Recently I started listening to podcasts from AXIOS, an online news source, and have especially enjoyed their coverage of science in general and specifically the COVID-19 pandemic.

They produced 5 short videos explaining the coronavirus vaccine that I found informative and want to share with you . Each is less than 5 minutes so in about 25 minutes you will learn much about the vaccine and hopefully be more confident in your decision to get vaccinated yourself, as I and my husband have been.

Here’s the intro from AXIOS and a link to the page where you can access all 5 videos. Below I have given you an outline so you know a little of what is in each episode, but I do recommend you listen to all of them in order. They are even appropriate for kids.

Vaccines: A short course from Axios

Vaccines have been used for centuries to fight disease but hesitancy and disinformation about them are spreading, jeopardizing the global fight against measles, COVID-19 and other diseases.

Axios’ science and health journalists will help you understand vaccines — how they work, how they’re tested and distributed, and where vaccine technology is headed.

This illustration, created at the Centers for Disease Control and Prevention (CDC), reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. In this view, the protein particles E, S, and M, also located on the outer surface of the particle, have all been labeled as well. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19). CDC/ Alissa Eckert, MS; Dan Higgins, MAMS, public domain

1. Vaccine basics

Learn how vaccines are made and how they work. Understand the immune system-T cells and antibodies.

Review the concept of herd immunity and why it’s so important.

2. Study and testing of vaccines

Find out why the research and development of vaccines costs $100 of millions. See the 3 phases of the process and why this one progressed faster than ever before.

3. Distribution of vaccines

Understand why vaccine distribution differs from other drugs-including the manufacturing, selling, buying, and transporting.

Three days after my first vaccination the soreness in my arm was almost gone, and I had no redness or swelling. After the second shot, minimal soreness. No other side effects to report. I feel fortunate.
