A skincare scientist named Carolina Reis Oliveira has revealed that the presence of zombie cells in our skin could be causing us to age faster than normal. These cells, also known as senescent cells, are essentially inflamed cells that have stopped dividing but have not died. Carolina likened them to a rotten apple in a bunch, spoiling the healthy cells and accelerating the aging process.
In an interview on the Longevity Optimization podcast, Carolina explained that skin aging is primarily influenced by two processes: intrinsic aging, which involves the deterioration of cell quality, and extrinsic aging, caused by external factors like UV rays, pollution, and smoking. The accumulation of senescent cells from these processes leads to inflammation and speeds up the aging of healthy cells, resulting in issues like sagging, wrinkles, and a weakened skin barrier.
However, Carolina reassured listeners that it is possible to combat the effects of senescent cells and reverse the signs of aging. By reducing the number of old cells in the skin, space is created for healthy cells to replicate and function optimally, producing collagen and restoring a more youthful appearance.
Collagen, the most abundant protein in the human body, plays a crucial role in maintaining skin elasticity, hydration, and firmness. As we age, collagen production naturally declines, leading to visible signs of aging such as wrinkles and sagging skin. While collagen-based skincare products may offer some benefits, their efficacy varies, and experts suggest that stimulating collagen production within the skin through certain ingredients may be more effective.
In addition to skincare products, lifestyle factors like regular exercise, proper hydration, and a nutrient-rich diet can help reduce the presence of senescent cells in the skin. Carolina emphasized the importance of internal health, including addressing nutrient deficiencies, gut health, and inflammation, as these factors can impact the skin’s aging process. Research has also shown that intermittent fasting may help decrease the number of senescent cells in the body.
Overall, by understanding the role of senescent cells in skin aging and implementing strategies to reduce their impact, individuals can work towards maintaining a more youthful and healthy complexion. It’s not just about looking younger; it’s about promoting skin that behaves like younger skin from the inside out.
