Disclaimer
This page is intentionally detailed and plain-spoken. CosmeticFountain is an educational evidence-review publication, not a medical service, professional consultation, product-safety certification, or guarantee of results.
Not medical advice
CosmeticFountain provides general educational information about cosmetics, beauty devices, ingredients, claims, and scientific evidence. Nothing on this website, in the newsletter, or in any downloadable material is medical advice, diagnosis, treatment, prescribing, or a substitute for advice from a licensed physician, dermatologist, pharmacist, or other qualified health professional.
No doctor-patient relationship
Using this website, reading a review, subscribing to the newsletter, sending feedback, or clicking a link does not create a doctor-patient, clinician-patient, attorney-client, or professional advisory relationship with CosmeticFountain, its operators, reviewers, contributors, or agents.
Do not delay or disregard professional medical advice
Do not delay, ignore, or stop professional medical care because of something you read here. If you have acne, rosacea, eczema, psoriasis, melasma, hair loss, allergic reactions, wounds, burns, eye symptoms, infection signs, pregnancy-related concerns, medication interactions, implanted medical devices, or any other medical condition, speak with a qualified professional before using a product or device.
Emergency or serious reaction
If you experience trouble breathing, swelling, severe rash, eye injury, burns, chest pain, fainting, infection, severe pain, or any urgent symptom, seek emergency care immediately. Do not rely on this website in an emergency.
No guarantee of results
Evidence grades describe the strength and directness of available evidence. They do not guarantee that a product or device will work for you. Individual results vary based on skin type, hair type, health status, medications, technique, adherence, dose, frequency, storage, product batch, and many other factors.
Use products and devices at your own risk
You are responsible for reading labels, instructions, warnings, contraindications, and local regulations before using any cosmetic product or beauty device. Patch testing, professional supervision, or complete avoidance may be appropriate for some users. Home-use devices can cause harm if misused or used by people with contraindications.
Regulatory and safety information can change
Cosmetic formulas, device specifications, labeling, warnings, recalls, laws, and scientific evidence can change after publication. A review may become outdated. We aim to refresh verdicts, but we cannot promise that every page reflects the latest formulation, safety notice, regulatory action, or study.
Evidence limitations
Peer-reviewed does not always mean reliable, clinically meaningful, independent, or directly applicable. Many cosmetic studies are small, sponsor-funded, short-term, subjective, unpublished, or based on ingredient-level rather than finished-product evidence. We may downgrade evidence when methods, endpoints, conflicts of interest, or directness are weak.
Affiliate and commercial disclosure
CosmeticFountain may earn a commission if readers click certain links or buy through certain partners. This does not affect our grade. Affiliate relationships, sponsorships, free samples, or other commercial relationships should be disclosed where applicable. If a disclosure is missing, contact us so it can be corrected.
No endorsement or safety certification
A favorable verdict does not mean a product is endorsed, approved, guaranteed safe, appropriate for every person, or superior to medical care. An unfavorable verdict does not necessarily mean a product is unsafe or useless for every person; it may mean the evidence is insufficient, indirect, or not clinically meaningful.
External links
External websites, retailers, journals, regulators, and newsletter platforms are controlled by third parties. CosmeticFountain is not responsible for their content, privacy practices, product fulfillment, pricing, claims, or safety information.
Corrections
We welcome corrections and source updates. Scientific evidence changes, and honest corrections are part of the methodology. Corrections do not create liability for prior reliance on older information.
