The site’s content
Everything on Before You Buy Guide is provided for general information. We work hard to be accurate, but products change, prices move, and we make no warranty that any information is current or error-free. Verify critical details (price, specs, compatibility, ingredients) with the retailer or manufacturer before buying.
In plain terms
We check prices on a schedule and log corrections publicly, but a spec sheet can change the day after we read it. The retailer’s listing is the final word at checkout.
Not professional advice
Nothing here is medical, dermatological, veterinary, financial, or other professional advice. Skincare guides in particular are research summaries, not prescriptions. Consult a professional for individual concerns.
In plain terms
We can tell you which retinol formula owners rate highly; we can’t tell you what your skin needs. Different jobs.
Intellectual property
Content on this site is ours. Quote briefly with attribution and a link; don’t republish wholesale.
Liability
To the maximum extent permitted by law, we are not liable for damages arising from use of this site or reliance on its content, including purchases made from third-party retailers we link to.
In plain terms
We compile the best available evidence carefully, but the buying decision — and the purchase itself, on the retailer’s site — is yours.
