What Is Cell Turnover?
Cell turnover is the skin’s natural renewal process. Old, damaged skin cells rise to the surface and shed, making room for new, healthy ones underneath. This process keeps your skin looking smooth, even, and vibrant.
How Often Does It Happen?
In young, healthy skin, the cycle takes around 28 days. But as we age, this slows down – sometimes taking over 40 days. When turnover slows, dead skin builds up, leading to dullness, uneven tone, clogged pores, and rough texture.
What Slows It Down?
How to Support Healthy Cell Turnover
Regular exfoliation helps slough off dead skin cells and encourages renewal.
Retinoids (like retinol and tretinoin) are proven to increase cell turnover, improve texture, and boost collagen production. Start slowly if you're new to them, and always follow with sunscreen.
Hydrated skin functions better overall. A strong moisture barrier supports cell function and repair. Choose a moisturizer with ingredients like hyaluronic acid, ceramides, or glycerin.
UV damage slows turnover and accelerates aging. Daily broad-spectrum SPF is non-negotiable, even on cloudy days.
Chemical peels, laser treatments, and microneedling can all stimulate turnover and reveal brighter, smoother skin underneath. Talk to your dermatologist about which treatment is right for your skin.
The Bottom Line
Cell turnover is your skin’s built-in renewal system—but it needs support. With the right products, habits, and professional care, you can promote healthier, more youthful-looking skin at every age.
