References are divided by what they can verify. A seller page can document what is advertised; a professional clinical source is better suited to understanding diagnosis and treatment of nail disease.
Product-supplied materials
The user supplied original Kerassentials artwork with packaging front and back, a formula ingredient panel, 15 mL size and the caution/suggested-use text. These images establish what the artwork states, not regulatory approval.
Official seller page
https://kerassentials.com/ — details about marketed formula ingredients, advertised bonuses and guarantee. The site includes marketing claims that are attributed rather than adopted as established facts.

https://www.aad.org/public/diseases/a-z/nail-fungus-treatment — dermatologist-reviewed information on diagnosis, topical and oral treatment, nail growth and limitations of home remedies.
American Academy of Dermatology — overview

Commercial-price caveat
Prices shown on the homepage are indicative figures appearing on independent seller-style listings. The transaction page linked from each purchase CTA, not this site, governs current charges and return terms.
