Information on reviews

We do not carry out separate checks on reviews to ensure that the reviews shown are actually from consumers. All visitors to our website can submit reviews for our products. The submission of reviews is not tied to an user account or similar. All reviews go through Bazaarvoice's rigorous moderation process. The reviews are checked by a Natural Language Processing (NLP) tool and, if the content needs an additional review (e.g. suspected spam, inappropriate content), passed to Bazaarvoice’s human moderator. The human moderator will read and tag content for approval, rejection, or review. However, the product sentiment (whether positive or negative) is not decisive for whether a review is approved, rejected or reviewed. Detailed information on Bazaarvoice’s rigorous moderation process can be found here.

Koishimaru Silk

A timeless link to unparalleled beauty

Close-up image of a bundle of Koishimaru Silk.

The Incredibly Luminous Hands of
Silk Spinners

Many workers stand in line, spinning silk thread in a factory.

SENSAI’s origins trace back to its predecessor company, formally in the spinning industry. It was during a visit to a spinning mill that the exceptionally beautiful hands of silk spinners caught the attention of our scientists.

Decades of research followed, until one day the secret behind their beautiful hands was discovered - a protein found in raw silk fibre, which has since been at the heart of every SENSAI product.

Koishimaru – A Precious Silk of Japan

An abundant wave of silk thread shimmers and glows on a black background.

Our story cannot be told without Koishimaru Silk. Once reserved for the Japanese Imperial Court, this extraordinary silk is renowned for its unmatched fineness and lightness, boasting a resilience and suppleness.

The fabric has a lustrous sheen that glows from within, an exquisitely smooth touch and a warmth and moisture at the same time. A garment made from Koishimaru Silk adjusts naturally to every movement of the body and drapes effortlessly like a second skin. Cherished for its exceptional qualities, this silk was once exclusive to the Japanese Imperial Court.

Koishimaru Silk × Skin Science

In the continuous pursuit of radiantly beautiful skin, SENSAI joins the essence of Koishimaru Silk with the latest in skin science. Revered for its unmatched resilience and exquisite lustre, this precious silk, known for its ability to promote the production of hyaluronic acid, has long inspired SENSAI’s approach to anti-ageing skincare. Its legacy continues to inform the development of new skincare innovations today.
