Skin Cell Turnover: What’s Happening Beneath the Surface
- Skin cells form at the bottom layer of the epidermis and travel up the top layer.
- Your skin cell turnover rate naturally slows with age.
- Both at-home and professional exfoliation treatments can speed up your skin cell turnover rate.
Creating that lit-from-within glow isn’t just about the skincare products you apply. It’s also about what your skin does naturally every single second. What is skin cell turnover, and why does it matter? Skin cell turnover is the biological process in which your skin produces new cells in the dermis, the deepest layer, which then travel to the surface to replace old, dead cells. Understanding this natural cycle is the holy grail for anti-aging and clearer skin.
The Science of the Renewal Cycle
New skin cells form in the stratum basale, which is the deepest layer of the epidermis. These cells take a gradual journey upward to the stratum corneum, the skin’s top layer. As they travel, new cells push older cells up. This happens at the same time as desquamation, another natural process in which the body sheds dead skin cells. Desquamation needs to happen at the right rate for glowing skin. Slow turnover can cause dullness and signs of aging, while rapid turnover can lead to flakiness and other texture issues.
How Long Does Skin Renewal Take? (The Age Timeline)
As we age, our skin cell turnover rate slows down. The average time it takes a skin cell to form, travel through the layers of the epidermis, and sit on the outer layer before shedding is:
- Around 14 days for infants (this is the secret of baby soft skin!)
- 21-28 days for teens and 20-somethings
- 28-45 days for people in their 30s and 40s
- 60-90+ days for those in their 50s and older
Aging can strengthen cellular “glue” that holds dead skin cells together, slowing down the turnover process.
Signs Your Skin Cell Turnover Is Sluggish
Slow skin cell turnover leaves visible signs. If you’ve noticed any of these skin concerns, your cell turnover is likely sluggish.
- Texture: Your skin may feel rough or bumpy to the touch.
- Dullness: Your complexion may appear sallow or not reflect light.
- Congestion: Signs of congestion are persistent blackheads, milia (tiny white bumps), or breakouts that feel trapped under the skin.
- Fine lines: Buildup on the skin’s surface can make your dehydration lines look deeper.
- Pigmentation: While slow skin cell turnover doesn’t necessarily cause dark spots or acne scars, it does make them take months or longer to fade.
How to Support and Optimize Your Skin Turnover
If you’re concerned about any of these signs of slow cell turnover, both at-home and professional treatments can help.
At-Home Support
In your at-home skincare routine, hydration is essential for good enzyme function. Retinoids are considered the gold standard for increasing cell turnover, and chemical exfoliants, like lactic acid, glycolic acid, and other AHAs, dissolve the “glue” holding dead skin cells together.
The Professional Advantage
While at-home products can improve your complexion, over-exfoliating can damage your skin’s barrier, which leads to problems like dryness, redness, irritation, and acne. Professional treatments like dermaplaning, chemical peels, and Hydrafacials provide deep, precisely controlled exfoliation that renews your skin beyond what home remedies can achieve.
