Korea Glow Report answers the beauty questions US readers search for every day: why sunscreen pills, which actives can share a routine, why acne marks turn red or brown, why hair feels waxy after washing, why nails peel in layers and why foundation separates by midday. Each guide explains the mechanism, summarizes what peer-reviewed studies and regulators such as the FDA say, and ends with a clear next step.

Six topics

• Sunscreen science: UV filters, labels and regulation, how much to apply and how sunscreen wears under makeup.
• Ingredients & layering: what common actives do, which combinations work together and how barrier creams are built.
• Acne marks & texture: red and brown marks, exfoliation, clogged pores and rough texture.
• Hair & scalp science: buildup, porosity, silicones and bond-repair products.
• Nails & makeup wear: peeling nails, gel manicures and UV lamps, and foundation that lasts.
• K-beauty decoded: Korean products, routines and regulation, drawing on Korean-language sources that rarely reach English readers.

How we research

Articles are researched and edited by H. Lee. We start with regulators and professional bodies such as the FDA, the American Academy of Dermatology and the EU Scientific Committee on Consumer Safety, then the human studies behind each claim. Studies are reported with their size and duration, and claims in our evidence tables are graded Strong, Moderate, Limited, Lab-only or Guidance. The editorial policy explains the grading and how sources are dated.
