Your Skin Is Shedding Right Now: Understanding Skin Cell Turnover & How to Support It
How Often Does Your Skin Renew Itself?
Did you know your skin is constantly renewing itself? On average, your body sheds 30,000–40,000 skin cells every minute. That adds up to roughly 4 Kilograms of skin cells each year — a statistic that never fails to surprise.
But what does that mean on a smaller, more relatable scale?
Daily Skin Cell Shedding
Your skin is a living, breathing organ that’s always in motion. Each day, your body sheds an estimated 500 million skin cells. These cells come from the outermost layer of the skin, the epidermis, which acts as your primary barrier against the outside world.
Weekly Skin Cell Shedding
Over the course of a week, this natural process results in the loss of around 3.5 billion skin cells. While it sounds dramatic, it’s completely normal — and essential for healthy, resilient skin. This constant renewal allows new, healthier cells to rise to the surface, helping your skin maintain its protective function, texture and appearance.
Why Does Skin Shed in the First Place?
Skin shedding (also known as desquamation) is part of your skin’s renewal cycle, often referred to as cell turnover. New skin cells are formed in the deeper layers of the epidermis and gradually migrate upwards. As they reach the surface, older cells flatten, die, and are eventually shed.
This process helps:
- Maintain a healthy skin barrier
- Protect against environmental damage
- Regulate temperature
- Support even skin tone and texture
However, cell turnover slows with age, stress, sun exposure and certain skin conditions. When old skin cells linger on the surface for too long, skin can appear dull, rough or uneven — which is why exfoliation and in-clinic treatments can be helpful for some people.
Factors That Affect How Quickly Your Skin Sheds
Several internal and external factors influence skin renewal:
Age and Skin Renewal
Younger skin typically renews itself every 28 days. Over time, this process can slow to 40–60 days, contributing to dryness, congestion and texture changes.
Sun Exposure
UV radiation can disrupt healthy cell turnover, damage collagen and lead to uneven shedding. This is also one of the big factors in premature ageing.
Climate & Environment
Dry air, pollution and harsh weather can interfere with the skin barrier and shedding process.
Skincare and Exfoliation Habits
Over-exfoliation can damage the barrier, while too little exfoliation may allow dead cells to accumulate. Dermatologists are fans of harsh daily scrubs (such as those containing nut shells or large, jagged particles), which can create microscopic tears in the skin and erode the stratum corneum, or the outermost layer.
Supporting Your Skin’s Natural Renewal Process
Hydration
Well-hydrated skin functions better. Adequate water intake and barrier-supportive moisturisers help prevent flakiness and irritation.
Gentle Exfoliation
Exfoliation assists the skin in removing dead cells that don’t shed efficiently on their own.
Sun Protection
Daily sunscreen use helps preserve healthy skin renewal and prevents UV-related damage that slows turnover and can be a factor in premature skin ageing. If you ask Dr Rich what the best anti-aging cream is, he will always say SPF 50 sunscreen.
Dermatology Skincare Products That Support Skin Shedding
If you’re looking to support your skin’s natural exfoliation process, dermatology-guided skincare can help.
Chemical Exfoliators (AHAs & BHAs)
Chemical exfoliants dissolve the bonds holding dead skin cells together.
- Glycolic Acid (AHA): Improves texture and radiance
- Salicylic Acid (BHA): Penetrates pores and supports congestion-prone skin
These ingredients are commonly incorporated into dermatologist-recommended peels and home-care products. are generally preferred over physical scrubs because they dissolve the “glue” between dead cells without creating micro-tears like some harsh daily scrubs that cause micro-tears, inflammation, clogged pores and more.
Retinoids (Vitamin A Derivatives)
Retinoids are widely used to support skin renewal and texture refinement.
- Encourage more efficient cell turnover
- Support collagen production
- Improve uneven texture and tone
They are often introduced gradually to minimise irritation and are best guided by a dermatologist.
- Retinol & Retinoid Products
- Retinol: A gentler, over-the-counter form of Vitamin A that encourages skin renewal.
- Prescription Retinoids: Stronger retinoids like tretinoin are often recommended by dermatologists for more significant skin concerns like acne and signs of aging.

Enzyme-Based Exfoliation
Fruit enzymes gently digest surface proteins, making them suitable for sensitive skin types who struggle with acids or scrubs.
Enzyme-based products gently exfoliate the skin by breaking down the proteins that hold dead skin cells together. These products are often a good alternative for those with sensitive skin who may find acids or scrubs too harsh.

Hydrating Moisturisers
When your skin sheds, it’s important to lock in moisture to prevent dehydration and keep the skin barrier intact. Moisturisers help replenish moisture and create an optimal environment for skin regeneration.
- Ceramides & Hyaluronic Acid
- These ingredients strengthen the skin’s natural barrier and prevent moisture loss.
Barrier-Supporting Moisturisers
Ingredients such as ceramides and hyaluronic acid support hydration while skin renews itself, helping maintain comfort and resilience.
Chemical Peels (Professional & At-Home)
Chemical peels are designed to assist exfoliation of surface skin layers and support the skin’s natural renewal process. They range from mild at-home peels to more intense professional treatments.
- Superficial Peels – focus on texture & brightness
- Mild chemical peels that use AHAs or BHAs help exfoliate the skin without downtime.
- Professional Peels – delivered under medical supervision for targeted concerns
- Stronger chemical peels, such as TCA or glycolic peels, are typically performed by dermatologists and can offer more noticeable results.
Vitamin C Serums
While Vitamin C is often thought of as an anti-aging powerhouse, it also promotes cell turnover. Vitamin C helps brighten the skin and fades hyperpigmentation caused by sun exposure or acne scars. It can aid the shedding of skin cells by encouraging fresh, new skin growth.

- ENRICH ABC Serum
- SkinCeuticals C E Ferulic
Laser & Device Treatments That Support Skin Texture & Renewal
For patients looking for in-clinic options, device-based treatments can complement the skin’s natural renewal process by targeting texture, tone and collagen support.
At Dermatology Institute of Victoria and Enrich Clinic, dermatologists may recommend the following technologies depending on skin type and concerns:
Fractional Laser Treatments
Fractional lasers work by creating controlled micro-injuries in the skin, stimulating repair and renewal.
They can help improve:
- Uneven skin texture
- Fine lines
- Sun-related skin changes
By encouraging the skin’s natural healing response, these treatments support exfoliation and long-term regeneration.
Non-Ablative Laser Treatments
Non-ablative lasers target deeper skin layers while leaving the surface largely intact.
They are commonly used to:
- Improve skin tone and texture
- Support collagen remodelling
- Encourage gradual skin renewal with minimal downtime
Microneedling (Medical Skin Needling, The Secret)
Microneedling uses fine needles to create micro-channels in the skin, triggering repair pathways. Devices such as The Secret and Micro Needling help with collagen production as well as other benefits, including:
- Improved texture
- Enhanced penetration of topical treatments
- Support for smoother, more even skin
Light & Energy-Based Devices
Certain light-based treatments can help manage pigmentation, redness and textural irregularities by encouraging healthy skin turnover and barrier repair.
All treatments are assessed individually and tailored by dermatologists to ensure suitability and safety.
Vitamin C & Skin Renewal – How does it fit in?
Vitamin C supports skin brightness and collagen formation. While it doesn’t exfoliate directly, it works alongside the renewal process to improve the appearance of newly surfaced skin.
Sun Protection: The Final (Essential) Step
Freshly renewed skin is more vulnerable to UV damage. Daily sunscreen use helps protect the skin barrier, maintain even texture, and preserve the results of exfoliation or in-clinic treatments.
SPF Protection
After shedding skin cells, your skin is often more sensitive and prone to damage. Protecting your newly revealed skin with sunscreen is essential to prevent further UV damage and support the skin’s overall health.
