Cell Turnover and Aging Skin


cell turnover and aging skinOur skin is our largest organ, and the way it works truly fascinates me, but I suppose that is partly why I became an esthetician. Did you know that the cells of your epidermis (the outermost layer of skin) completely turnover on average every 28 days? Pretty amazing (and kind of gross knowing that most dust is actually dead cells that have shed)! This turnover is also called the Cell Renewal Factor or CRF. There are some factors that can change the rate at which our skin cells turnover, the biggest factor being age. Our cell turnover slows down as we age, and this is why we turn to things such as AHAs (alpha hydroxy acid) and BHAs (beta hydroxy acid) to help speed up that cell turnover.

Cell Renewal Factor that changes as we age:

Babies – 14 days
Teenagers – 21 – 28 days
Middle age – 28 – 42 days
50 and up – 42 – 84 days

As babies, our cell renewal factor is quick, which is why babies always have such soft,

smooth skin, as we age this factor slows down, we start to see the fine lines, and wrinkles in our skin, as well as start to see thinner skin with less elasticity. Our skin also has a tendency to feel more dry or dehydrated as we age as well. All of this causes the cells to stick instead of shedding from the skin because they are not turning over like they should be, which means new youthful skin is not appearing as quickly. There are many products, modalities, and treatments to help increase cellular turnover and increase collagen and elastin to help prevent aging. Some of these include enzymes and peels, microdermabrasion, dermaplaning, microcurrent, and ultrasonic facials. Using these treatments can help prevent, and to some degree, help to reverse the signs of aging.

 

Our skin starts to feel more dry and/or dehydrated as we age. These are not one in the same. Dry skin is a skin type, that is due to a lack of oil in the skin. Thus causing it to be dry. A dry skin type can show signs of aging sooner as the lines are more pronounced in a thinner, drier skin. Dehydration, which can happen to any skin type is a lack of hydration (water). As we age our body does tend to produce less oil, so although our skin type never changes, a normal or dry skin may see a more pronounced decrease in oil production, and increase in fine lines. Professional exfoliation and at home maintenance will help greatly with improving dry skin and aging, as well as a beauty oil’s such as omega_serum_2-copy-600x600SkinCatering’s Omega Serum  (in fact the entire advanced skin care line is a great way to increase cell turnover!) Dehydration, can be much easier to combat than dryness, as it is a condition and not a type. This could be caused by many things such as nutrition, sun exposure, medication, hormonal imbalances. Once you know the cause, you can start to treat your dehydration, hyaluronic acid, and a good moisturizer can help, as well as increasing your bodies hydration as a whole.

No matter how dry, dehydrated, or hydrated your skin is, your skin health should be a priority and it is not too early to start maintenance facials to prevent the signs of aging before they even start.
