Background & Nitty-Gritty of RatzillaCosme

RatzillaCosme is solely run by me, a trilingual 30-something based in Japan and Vancouver.

My main goal is to provide accurate, unbiased, and up-to-date information on J-beauty that is easy to understand. Everything you see (including ingredients) is outlined by me based on Japanese press releases.

I started this website over 10 years ago as an answer to the lack of reliable, in-depth information on Japanese beauty products. What started as a personal weblog for friends has become the largest English-language J-beauty resource site in the industry. In addition to a database with thousands of products, it also has guides and reviews.

For questions about this website, get in touch by leaving a comment under my posts, DM me on Instagram or Twitter, or email me through the contact form.

(You can write in either English, Japanese, or traditional Chinese.)

Affiliate Links

All the work you see — including CSS and HTML — is my own. There is no charge for accessing this site and keeping it running is incredibly labour-intensive. As such, affiliate links and advertising banners are a necessity.

Most outbound retail links you see are affiliate links. If you make a purchase through one of my affiliate links, I will earn a small commission. Commissions help keep RatzillaCosme but you are not obligated to click on or buy from any of these links.

Sponsored Content

I accept press samples but I do not partake in paid product placements (sponsored content).

Comment Policy

I welcome relevant and respectful comments. Comments which do not meet these standards will be removed.
