Disclaimer

SkinKnowledgeBase is an educational reference. It is not medical advice, diagnosis, or treatment.

We write about cosmetic-appearance topics: how skin looks, how ingredients are positioned in skincare, what cited sources say, and what product facts can be verified. We do not tell you what is medically right for you, and we do not replace a dermatologist, physician, pharmacist, or other qualified clinician.

Always consult a qualified clinician for medical concerns. Sudden, painful, asymmetric, vision-affecting, bleeding, infected-looking, or persistent skin changes should be evaluated by a dermatologist or physician. The same applies if a product seems to trigger swelling, hives, breathing symptoms, severe irritation, or symptoms near the eyes.

Information on this site reflects the cosmetic-appearance evidence cited on each page. We do not promise outcomes for any individual. Skin type, health history, product tolerance, routine consistency, medication use, environment, and many other factors affect what someone experiences.

We update content over time as new sources become available. Cited sources are verified at authoring time, but external sites can change without our notice. If a citation breaks, a claim needs more nuance, or a stronger source exists, corrections are welcome and appreciated.
