Aging and senescence are different
Aging is the passage of time. Senescence refers to the decline in physiological functions that accompanies aging. When cells that have lost their normal function (senescent cells) gradually accumulate, the functions of tissues and organs decline. These two are not the same.
Senescence was once thought to be a destiny built into our genes. However, in the last ten years or so, this view has changed. It is said thatthe influence of genes is about 20%, and the vast majority of the rest is due to lifestyle and environment. It is believed that the reason some people look younger than their age while others look older is because of the different amounts of senescent cells accumulated in their bodies.
The term longevity (Longevity) began to be used in this context. It is not just about living a long time, buthow long you can maintain a healthy state. This way of thinking has now spread into the field of beauty.
Not removing, but restoring
What to do with accumulated senescent cells. This is where the direction of research diverges.
One is the idea ofremoving senescent cells. This is the direction that many research institutions and cosmetic manufacturers are currently working on, known as senolytics.
What we see is a different direction. Instead of removing them, can we return them to a young state?
Inside senescent cells, there are accumulated proteins that were not properly processed. At the Longevity Science Laboratory of Yokohama City University, it was confirmed that reducing this amount causes the cells to start dividing again. Once a cell becomes senescent, it will never divide again ― this has long been considered a biological common sense, but that common sense has changed.
Senescent cells are not just waste. They play complex roles in the body. That is precisely why, instead of removing them, we return them to a young state. That is where we stand.

From the research team
We are a company born from the Longevity Science Laboratory of Yokohama City University. The knowledge accumulated in the laboratory and the wisdom of herbs that Ayurveda has carefully selected over thousands of years. Based on both of these, a team of longevity science experts creates the products.
PROFILE
Hiroki Taka
Ph.D. (Science)
Visiting Researcher at the Graduate School of Life and Environmental Sciences, Yokohama City University
Research and development of beauty and health longevity products at Ichiban Life Co., Ltd.
How cells age ― we have studied this mechanism for many years. Senescence involves specific changes occurring in the body. Understanding these changes is the starting point for thinking about how to deal with aging skin. That is our starting point.
Can be used in the morning
We have a preceding product calledRejuve Cream (Night Cream). It is a cream for nighttime care that generously uses natural oils.
Then, we received feedback from customers.― I want something that can also be used in the morning.
The Skin Serum was born from that feedback. It is an emulsion type with reduced oil content. Generously formulated with the proprietary ingredient Ayucelra®-SK※2, high-performance moisturizing ingredients such as Peresea※3 and Lipijuva※4 penetrate deep into the stratum corneum. It spreads easily and is not sticky, so it does not feel heavy during your morning routine.
It starts with the fresh scent of orange, then transitions to lavender, cloves, and rosemary. It is from essential oils, not fragrance.


Not white

When you pick it up, you will notice that it is not pure white. It has a slightly yellowish, natural beige color.
No artificial coloring is used.This color is the color of the 10 types of Ayurvedic herb extracts themselves that are formulated. If you formulate a generous amount of extracts, it naturally becomes this color. The fact that it is not white is proof of how much is in it.

How Ayucelra®-SK was created
considered beneficial for beauty
the optimal combination
We took our time choosing
Ayurveda has many herbs that have been used for beauty. We collected about 300 types from among them that are considered beneficial for beauty, and conducted research over 20 years. And what we arrived at is a combination of 10 types, starting withamla (Indian gooseberry). Amla is a herb that has been counted as one of the three great fruits in Ayurveda.
Even herbs with the same name differ in their contents
Just as wine has good and bad years, herbs differ in their contained ingredients depending on the place of origin, cultivation, and harvest season. Therefore, we order and analyze multiple lots of different origins and seasons for a single herb, and use only those that meet the standards. This process of selecting raw materials is the most time-consuming part.
