Cellular senescence has become a topic of growing interest in the field of dermocosmetics, especially regarding skin aging. Brands like Byoode, Medik8, Perricone MD, and Omorovicza have begun to explore this biological phenomenon which, although natural, can be accelerated by various external factors.
Cellular senescence occurs when cells stop dividing, causing tissue degradation and a significant loss of collagen and elastin. According to Estefanía Nieto, director of dermocosmetics at Medik8, this process is responsible for the appearance of wrinkles, sagging, and spots on the skin. This phenomenon is related to the “Hayflick limit,” a notion that determines how many times a cell can divide before its activity stops. Factors such as oxidative stress, excessive sun exposure, and an unhealthy diet can accelerate this process.
Marta Agustí, director of dermocosmetics at Omorovicza, emphasizes the importance of maintaining a proper skincare routine and a healthy lifestyle to preserve cellular health. Although cellular aging is inevitable, certain habits can help slow it down. The length and functionality of telomeres, structures that protect the DNA of cells, are crucial in this process, and a proper skincare routine can help preserve them.
Among the practices recommended by experts to prolong cellular life is the daily use of sunscreen. UV radiation and blue light are factors that can accelerate senescence, so Mireia Fernández, director of dermocosmetics at Boutijour, advises applying broad-spectrum sunscreens and reapplying them every two hours.
Adequate nutrition is also key in this process. A diet rich in antioxidants and anti-inflammatories, along with the incorporation of nutricosmetics, can provide internal defense, according to Sole Urrutia of Advanced Nutrition Programme. Finally, the choice of regenerating and antioxidant cosmetics plays a crucial role. Estefanía Nieto emphasizes the importance of including actives such as retinoids, peptides, vitamin C, and niacinamide in skincare routines to protect and regenerate the skin.
The market is responding to this demand with specific products to combat cellular senescence. Among them is Boutijour’s “Relief Sun Moisture,” a SPF 50+ sunscreen that incorporates antioxidants; Advanced Nutrition Programme’s “Skin Ultimate,” a nutricosmetic that protects the skin from within; and Medik8’s “R-Retinoate Day & Night Cream,” a cream with significantly superior efficacy to conventional retinol.
In conclusion, understanding how cellular senescence influences skin aging is essential to adopt measures that help slow down this process. The combination of sunscreen protection, a balanced diet, and the use of specific cosmetics are presented as essential pillars to keep the skin young and healthy over time.
