The Clarifying Brightener
Kojic Acid
A naturally derived brightener that gently fades stubborn pigmentation.
What it is
In plain language
Kojic acid is a by-product of the fermentation of rice — most often associated with the production of sake. It has been used in Japanese skincare for centuries as a precision brightener for uneven tone.
The science
How it actually works
Kojic acid inhibits tyrosinase, the enzyme that produces melanin. By interrupting melanin synthesis at the source, it gradually fades existing pigmentation and prevents new spots from forming. Unlike hydroquinone, it works through chelation of copper rather than melanocyte toxicity.
