Golden Keys to Boost
Skin Cell Turnover
How the skin renews itself — and the two clinical methods practitioners rely on most to accelerate it.
Introduction
Why Turnover Matters
Skin cell turnover not only affects the visible appearance of the skin but also serves a vital biological function by shielding against UV rays, environmental stressors, and external irritants. Each skin cell operates on its own predetermined lifespan. If all cells followed the same schedule, our skin would shed entirely at once, akin to a snake shedding its skin.
As cells ascend to the surface and are shed, deeper layers of the skin receive signals to generate new cells, ensuring a continuous renewal process.
How Cell Turnover Operates
In young adults, skin cell turnover takes around 28 days, with cells spending about 14 days in transit from the lower layer to the surface. Once there, cells remain for another 14 days, protecting against environmental factors before shedding naturally.
Various factors like age, sun exposure, and stress can affect turnover, impacting skin hydration and barrier function. Exfoliation aids turnover by removing old cells.
Aging, Acne, and Slowing Turnover
As we age, skin cell turnover slows down. For instance, a 50-year-old’s skin may take up to 50 days to renew itself, while mature skin might take up to 90 days.
Promoting cell turnover in skincare routines helps combat aging signs like fine lines and discoloration. In acne, slowed turnover contributes to pore clogging, emphasizing the need for turnover promotion in anti-acne strategies.
The Turnover Cycle, by Age
Knowing where a patient sits on this curve is what separates a protocol that works from one that irritates. Treatment intervals, acid strength, and expected downtime all shift with the underlying renewal rate.
The Magic of Skin Regeneration: Microneedling
There are various measures to boost skin cell turnover, each with its unique effectiveness. Two particularly practical methods include microneedling and chemical peels.
Microneedling creates microchannels in the skin using fine needles, stimulating the production of new cells, enhancing cell turnover, and improving skin texture. It’s a popular non-invasive procedure used to address issues such as aging skin, acne scarring, hyperpigmentation, and more.
Proper understanding of microneedling’s treatment nuances, execution, pre- and post-care, personalized treatment protocols, and complementary skincare products is crucial for skincare practitioners.
Chemical Peels
Chemical peels involve using natural or chemical acids to exfoliate the skin’s upper layers, removing old and damaged cells. This process stimulates new cell production and improves skin texture, thereby increasing skin cell turnover.
Professional chemical peel application by a trained individual can yield remarkable results. Peels can address various skin concerns like hyperpigmentation, fine lines, surface roughness, and acne.
Acids, Percentages, and pH
Understanding the types of acids, their applications in skincare, and the percentage and pH for each acid to address specific skin concerns are crucial aspects of chemical peel treatments.
This is where most practitioners get stuck. The same acid at two different concentrations, or the same concentration at two different pH values, produces very different outcomes on the same face. Getting it right is a matter of trained judgment, not product labels.
