Editorial Standards

Cosmetic-appearance scope only

SkinKnowledgeBase is a cosmetic-appearance reference. We explain the appearance of fine lines, under-eye puffiness, uneven-looking tone, texture, hydration, and product facts. We can describe how an ingredient is positioned to support the look of skin, or how a product’s cost and formulation facts are represented.

We do not diagnose medical conditions. We do not claim to treat disease, cure disorders, prescribe routines, or replace a clinician. If a skin change is sudden, painful, asymmetric, persistent, vision-affecting, bleeding, infected-looking, or otherwise concerning, the right next step is medical care.

Consumer language first

Most people search in plain language. We use names like “wrinkles,” “puffy eyes,” and “under-eye bags” before technical alternatives. Technical names still matter, so we include them when they help readers or search systems connect related evidence.

Owned-product transparency

SKB maintains an internal product knowledge base. When a question naturally touches a concern or ingredient those products address, they can be considered for the page’s Ranked Product callout. Selection is governed by relevance, evidence strength, and forced-fit risk, not by brand affiliation. If a product is selected, the page says so plainly. If no product fits, we say there is no Ranked Product.

Source quality

We prefer peer-reviewed research, dermatology institutional pages, regulatory references, manufacturer clinical data, official product pages, clinical guidelines, and medical references. Product-fact claims can use official product pages. Appearance and mechanism claims need stronger support. Mixed evidence is described as mixed.

No paid placement

We do not publish sponsored articles, affiliate-driven rankings, or advertorials dressed as education. Product alignment is documented; it does not override relevance.
