An evidence review, not medical advice
The content on this site is a review of published evidence and regulation. It is not a diagnosis, not a treatment recommendation, and not a substitute for a consultation with a clinician who has examined you. It deliberately does not recommend for or against any supplement, and it does not state what any individual should do.
What the evidence does and does not show
The claims the evidence supports are stated as supported, and the claims it does not carry are stated as not supported. Where a question is unresolved, this site says that it is unresolved rather than resolving it by tone. A fact about collagen and a claim about a swallowed product are graded separately, because in this subject they are not the same statement.
No guarantee, and no booking
No outcome can be guaranteed, and nothing on this site is an offer of assessment, treatment or consultation. It is not a booking page, and no claim here should be read as an invitation to arrange anything. A decision about any supplement, topical or procedure is an individual clinical question, and a supplement is not suitable for everyone.
When to seek care
A mole or patch that is changing, a lesion that bleeds or will not heal, skin that is persistently red, painful or broken, or a reaction that does not settle should be assessed by a clinician. Contact the hospital’s outpatient channels or attend a dermatology service rather than relying on a website.
