How we check our answers

Where answers come from

1. FDA drug labels (DailyMed) and the FDA over-the-counter acne monograph, for acne actives like benzoyl peroxide, salicylic acid and adapalene.
2. Peer-reviewed studies and reviews, found on PubMed and in dermatology journals.
3. The American Academy of Dermatology, DermNet and the FDA's cosmetics pages for general skin-care guidance.

How we rate a pair

1. Same routine is fine: no known problem, and the two can be layered.
2. Space them out: better at different times of day or on different nights, usually because both can irritate.
3. Avoid together: a label says not to combine them, or they double up on the same kind of ingredient.

When no study looks at a pair directly, we say so on the page ("expert consensus") instead of pretending there is one. When the evidence is mixed, we pick the gentler option.

How we write and check a page

1. We start from the sources: FDA labels, dermatology organizations like the AAD, pregnancy services like MotherToBaby, and peer-reviewed studies.
2. Every health claim names its source on the page and links to it, with a line saying what we took from it.
3. When sources disagree, the page says who says what.
4. Each page shows the date its sources were last reviewed.

Our pages are not written or reviewed by a doctor. That’s why every answer points to the source it comes from, so you and your doctor can check it.

Who makes this site

askyourskin is made by Final Agency. We also make MySkincare, a skin-analysis app: the tools here are free and work without it, and pages show a link to it at the end.
