RAHAB R&D is slightly different from general beauty salons. Combining knowledge of regenerative science and medicine with beauty, it is an R&D private salon that addresses each individual's skin and body through continuous daily research and verification.
Through a single bed and a fully private room, we provide attentive counseling and highly specialized care. As a place where beauty professionals also come to learn, we continually update our methods and products.
Our salon has introduced an ultra-low temperature freezer capable of -60℃, which is also used in medical institutions. The conditioned media beauty serum used (Liberna 3000) is stored at -60℃ until right before opening. It is managed in a frozen state and thawed at the time of treatment to be applied to the skin.



Nice to meet you. I am Aya Endo, representative of RAHAB R&D. It has been 30 years since I stepped into the world of beauty. During this time, I have faced numerous skin and body concerns. What I arrived at through that experience was not temporary healing or trend-chasing care, but 'carefully building up approaches to bring out the innate power of the skin.' RAHAB R&D (Research & Development) is not an ordinary beauty salon. It is an 'R&D salon' where I continuously verify and evolve original methods and carefully selected products that I felt confident in through 30 years of field experience. Precisely because it is a small salon with one bed and a fully private room, we can listen deeply to the voice of each customer's skin and deliver uncompromising technology. 'I couldn't be satisfied anywhere I went,' 'I want to meet a professional to whom I can entrust my skin'—I created this place for you who wish for that. With carefully selected technology and products, we will consider the future of your skin together with you.
For one customer per day, therapists Endo and Sano each—and sometimes both—face you exclusively.
As a hairdresser, spanist, and aesthetician, I have pursued "beauty" and "comfort" in the field of beauty for many years.
What I value while continuing to touch customers' skin and bodies in my work is not only superficial care, but also observing the condition of the mind and body as well as various balances (harmonies).
With this in mind, based on my past experience in the field, I incorporate advanced analysis approaches to understand each customer's condition from multiple angles and provide care tailored to each individual.
Focusing not only on superficial beauty but also on the charm that the person inherently possesses, I explore beauty care that addresses them from the inside. Fusing past beauty experience with future beauty possibilities, I deliver care that stays close to each individual's beauty.

This time, I requested the 'Current Condition Custom Course'.
First, my entire body was scanned with 'frequency sound wave equipment' to balance the overall state. I was surprised at how easy it was to have my body examined and adjusted just by wearing headphones while sitting, and it was a very mysterious and interesting experience to see the issues inside my body visualized, which I couldn't understand on my own.
In the body treatment, I received careful care using oil and a spherical tool. My body warmed up gently during the treatment, making it a blissful time. After it finished, my whole body felt refreshed and light, and I was surprised by the results as I felt my body had tightened.
I was able to refresh both mind and body. I would definitely like to request it again.
