About us
TroubleNote is run by KW Cosmetic Content Team. We organize common concerns about breakout-prone skin, with the evidence behind each answer.
What we cover
We sort questions about breakout-prone skin into six topics.
- Causes & Areas: Chin, mouth, forehead, back / periods, stress
- Types: Comedones, pustules, nodules / marks vs scars
- Care: Cleansing, routine, moisture / teens, men
- Ingredients: Salicylic acid, niacinamide, centella
- How to Choose: Side-by-side criteria by concern
- Quick Q&A: One question, one answer
TroubleNote is the English edition of a Korean site, 트러블노트 (한국어). Each English article is adapted from a Korean article with the same facts, figures and sources.
Who runs this site
| Operator | KW Cosmetic Content Team |
|---|---|
| Website | https://thetroublenote.com/en/ |
The operator also runs a Korean cosmetics brand, SKIN9HARI. Because of that, some articles may end with one block of product information from the operator, and that block says so. We never place products in the middle of an article.
What this site does not do
- It does not replace diagnosis or medical care. If your symptoms are severe or last a long time, consider seeing a dermatologist.
- We do not rank specific products or run banner ads.
- We do not use personal reviews or video comments as evidence for facts.
How we write and update articles is explained in our editorial policy, and the material we cite is collected on our sources page.
