Overview
On average, your skin completely renews itself every 30 days—this process is known as “skin cell turnover.” In this process, dead skin cells are shed to make room for new ones. When your skin is healthy and hydrated, this occurs without you knowing it—skin cells, after all, are invisible to the naked eye.
However, several factors—including having dry skin, ageing or following improper skincare practices - can slow epidermal turnover, resulting in an accumulation of dead skin cells on your face. If left unaddressed, this buildup of dead skin cells can cause your skin to develop a rough or dull appearance. In this guide, we’ll explain what causes dead skin cell buildup and reveal some of the skin concerns associated with dead skin cells. You’ll also learn how to get rid of dead skin cells on the face without disrupting your skin’s natural protective barrier so that you can restore soft, healthy-looking skin.
FACTS ABOUT DEAD SKIN CELL BUILDUP
- Every minute, you shed between 30,000 and 40,000 skin cells - adding up to roughly 50 million dead skin cells shed per day, on average.
- Epidermal turnover slows with age. Dryness and dehydration can also affect how quickly your skin turns over.
- Dead skin cell buildup can result in a dull, uneven complexion. In some cases, dead skin can contribute to clogged pores and blackheads.
- Regular exfoliation with a gentle exfoliant can help remove dead skin cells and promote a smoother, more radiant complexion.
- There are two types of exfoliation that can help remove dead skin cell buildup: physical exfoliation (also known as “manual” or “mechanical”) and chemical exfoliation.
Frequently Asked Questions
-
1. Is it possible to remove dead skin cells?
Yes! Dead skin cells can be effectively removed through gentle exfoliation. Chemical exfoliants like AHAs and BHAs, or mild physical exfoliation, help shed dead cells, revealing smoother, brighter skin without disrupting the natural skin barrier. -
2. How to remove hardened, dead skin?
Hardened dead skin can be softened with hydration and removed using gentle exfoliation. Use chemical exfoliants (like lactic or salicylic acid) and follow with a moisturizer to restore the skin barrier and prevent further buildup. -
3. What happens if dead skin cells are not removed regularly?
If not removed, dead skin cells can accumulate on the surface, causing dullness, rough texture, clogged pores, and breakouts. Over time, this buildup can also reduce the effectiveness of skincare products. -
4.Can over-exfoliation damage your skin barrier?
Yes! Excessive exfoliation can weaken the skin barrier, causing irritation, redness, dryness, and increased sensitivity. It may also lead to higher transepidermal water loss, making skin more prone to damage. -
5. Does humidity affect dead skin cell buildup on the face?
High humidity can increase oil production, which may trap dead skin cells and lead to clogged pores. This makes proper cleansing and gentle exfoliation essential, especially in humid climates like India.
