Mariann Skin Science is an independent educational skincare resource. We explain publicly available dermatology guidance, ingredient information, product-label concepts, and regulatory information in clear language so readers can make more informed decisions about everyday skincare.

What we publish

Our coverage focuses on skin-barrier care, acne-prone skin, sunscreen, common cosmetic ingredients, retinoids, moisturizers, cleansers, and practical routine planning. We aim to answer specific questions rather than publish broad or repetitive articles.

How our content is prepared

Articles are built from publicly available sources such as dermatology organizations, government and regulatory resources, peer-reviewed literature when appropriate, and manufacturer documentation for product-label facts. Sources are linked or identified when they materially support a claim.

We do not invent personal experiences, patient stories, testing results, professional credentials, or medical reviews. Mariann Skin Science is not a dermatology clinic and our editorial team does not present itself as licensed dermatologists.

Updates and corrections

We review articles when guidance changes, when a source becomes outdated, or when a factual correction is needed. Material corrections are handled according to our Corrections Policy.

What our guides can and cannot do

Our guides are for general education and product-category understanding. They cannot diagnose a skin condition, determine whether a prescription treatment is appropriate, or replace individualized advice from a qualified healthcare professional.
