What are zombie cells?
Zombie, or senescent cells, are cells that stopped dividing, but don't die when they should. "They hang around in the skin in a sort of half-alive, dysfunctional state," says Maxwell Stock, CEO and founder of Epicutis. This clinically grounded skincare brand focuses on long-term skin health, barrier integrity and longevity
Do senescent cells contribute to specific skin concerns?
There is growing evidence linking zombie cells to several skin conditions, like hyperpigmentation and wound healing. "Because they promote chronic inflammation," says Stock. "They can also worsen existing skin conditions. What's important to understand is that senescence isn't just a sign of ageing, it actively drives inflammation which is the underlying cause of everything you see on your skin."
How important is senescence research in today's skincare development?
Stock goes on to say that senescence research is transforming our approach to anti-ageing: "Instead of just treating wrinkles or pigmentation, the focus is on the root causes of ageing and cellular health. By targeting senescent cells, reducing their harmful signals, and protecting healthy neighbors, scientists are guiding the development of more effective, biology-driven skincare."
