Skin cells are constantly being replaced by new ones. This process is called “cell turnover” and occurs in cycles that last anywhere from a few days to several months. The rate at which these cells are produced depends on many factors, including age, gender, diet, and stress levels.
The Process of Skin Cell Turnover
Skin cells are continually being replaced as part of normal cell turnover. During each cycle, old skin cells die off and new ones are born. The rate at which skin cells are produced varies based on many factors such as how much sun exposure a person receives, their life style and what type of diet they eat.
When we’re young, our skin cells divide rapidly and are continually being replaced rapidly. As we get older, our skin cells become less active and slower to replace themselves. As a result, our skin becomes thinner and drier. This means that old skin cells remain on the surface of the body, causing wrinkles and other signs of aging.
However, there’s hope! You can help keep your skin looking youthful and supple by taking care of our skin daily with an effective anti-inflammatory skincare routine, eating foods high in vitamin C (like strawberries), drinking plenty of water, and getting regular exercise.
Approximate Skin Cell Turnover Time with Age
How Fast Does My Skin Turn Over?
It’s estimated that the average adult loses about one layer of skin cells every three days. Actually, the skin cellular turnover happens without you even noticing every second of every day. However, some people lose more than others. Cell turnover happens every day, but it’s most noticeable during times of rapid growth such as puberty, pregnancy, and menopause. During these times, the body produces more cells than usual, causing the skin to appear thicker and shinier. However, with increased number of cells the number of dead cells increases, resulting in duller looking skin in the long run.
When we’re stressed, our bodies release hormones such as cortisol that cause us to lose water weight and increase blood flow to our muscles. These changes lead to increased sweating and faster breathing, which causes our body temperature to rise. In turn, our skin becomes dryer and thinner, making it appear older than it really is.
How does the skin cycle work?
Our skin is the body’s largest organ. It is our first defense against external aggressors, germs, viruses, infections, temperature changes, moisture loss, temperature change, trauma and UV radiation (aka Sun). It consists of three distinct layers: skin surface (stratum corneum), epidermis, the dermis and the hypodermis layer. New skin cells are created inside the epidermis. The cells migrate to the skin’s surface as they mature pushing the deteriorating mature cells to the surface. While the cells are pushed up, they become flatter.
As they arrive to the surface top layer of the skin, they are mostly dead. Our skin naturally sheds or flakes off these flat dead skin cells from the skin’s surface as the new mature cells make their way to the surface to complete their skin cycle and cellular turnover.
How skin cycle and cellular turnover work
How does skin cycle affect skin barriers, microbiome and skin immunity?
The skin cycle is your skin’s rejuvenation process that takes an average of 28 days. It is imperative for the skin barriers, microbiome and skin immunity to function in their optimal peak. This protects and defends us from daily aggressors, inflammators, microbes and – basically the whole world.
The skin sheds the dead cells that are pushed to the surface keeping the itself working in top shape. However with increasing age or stress this cell renewal process can slow down. The slowing down of the clearing process results in accumulation of more and more dead cells on the skin surface.
Additionally, decrease in collagen, elastin and hyaluronic acid reservoirs result in decreased look of elasticity, firmness with increased roughness, loss of moisture, dullness and uneven texture. The skin with the accumulation of these dead cells would be more prone to inflammation, irritation and other skin health challenges leading to disruption of skin barrier, microbiome and skin immunity functions and balance.
How your skin defends you
How can you support your skin cycle: Exfoliation
When you start seeing more dullness, dryness and rough texture, this is the time when our skin needs a bit of assistance to avoid clogging the pores and to return to its glowing self.
Exfoliation is an important part of your skincare routine to lift away dead, dry skin cells on the skin’s outer surface to reveal the fresh, healthy layers of skin beneath. Gentle exfoliation also helps to release the dead layer kindly so the products you apply afterwards will be absorbed quickly and work more effectively.
We prefer a gentle exfoliation instead of harsh damaging exfoliation procedures that can hurt the barriers, microbiome leading to more signs of inflammation.
Our HONEYACTIVE BEAUTY MASK is designed to visibly help unblock and detoxify the pores, smooth uneven rough texture and diminish the appearance of fine lines for a glowing appearance of the skin.
