Cosmetic vs Therapeutic Peptide Claims
The distinction between cosmetic and therapeutic claims and how regulatory classification works.
Last updated: 29 March 2026
Cosmetic vs therapeutic definitions
Cosmetic claims: improve appearance, texture, or sensory properties without treating or curing disease. Examples: 'improves skin smoothness', 'enhances elasticity'. Therapeutic claims: treat, cure, prevent, or manage disease or condition. Examples: 'treats acne', 'heals wounds', 'reduces inflammation'.
The distinction is based on the intended use and claimed effect, not the product itself.
Regulatory implications
Products with cosmetic claims are regulated as cosmetics in Australia (less stringent requirements). Products with therapeutic claims must comply with therapeutic goods regulations (more stringent, including registration on ARTG).
Mislabelling a therapeutic product as cosmetic is a violation.
Evidence standards
Cosmetic products: evidence requirements are less strict. Subjective assessments and in-vitro studies are acceptable. Therapeutic products: clinical trial data, rigorous testing, and independent evidence are required.
A peptide can have strong cosmetic evidence but weak therapeutic evidence.
Identifying hidden therapeutic claims
Be alert to disguised therapeutic language: 'anti-aging' (implies treating ageing disease), 'promotes natural healing' (implies therapeutic effect), 'supports collagen production' (implies disease-related benefit).
Cosmetic marketing often uses implied therapeutic language. Read carefully.
