Sarah Taylor
Korean Skincare Specialist & Beauty Educator
Sarah Taylor holds a BSc in Cosmetic Science and has spent over 12 years working within the Korean beauty industry — first as a product development consultant for K-beauty brands, and more recently as a skincare educator helping consumers understand the science behind the ingredients they use.
Her work has taken her from product development meetings in Seoul to consumer education across the UK and Europe. She specialises in ingredient functionality, skin barrier science, and translating clinical research into practical, accessible guidance for everyday audiences.
Sarah is a certified skincare educator and has contributed to brand training programmes, retail staff education, and consumer-facing skincare content for over a decade. She is particularly known for her evidence-first approach: where the science is limited or contested, she says so clearly, rather than overstating what an ingredient can do.

Our Editorial Standards
No product promotion
We do not accept payment for coverage, sponsored posts, or affiliate arrangements on ingredient and guide content. When we describe what an ingredient may do, that assessment is based on published research — not brand relationships.
Evidence-first language
Where clinical evidence is strong, we say so. Where it is limited or preliminary, we say that too. Phrases like "may help" and "evidence is limited" are deliberate — they reflect the actual state of the science.
No medical advice
This site provides skincare education, not medical advice. We recommend consulting a qualified dermatologist for persistent skin concerns, suspected conditions, or questions about prescription-strength actives.
Regular content reviews
All articles are reviewed periodically and updated when new evidence or formulation standards emerge. Each page carries a publication date and a "last reviewed" date so you can see when it was last checked.
