Why SSL verification is listed alongside domain history and business registration
Valid SSL certificate on checkout is grouped with domain history, registered business entity, and working contact address — four specific facts worth checking together, not in isolation.
Why this is worth checking yourself, not just taking on trust
The exact checks we ran on DermaCept — and how to run them on anything yourself is the title of the site's own dedicated verification guide, worth reading if this process interests you generally.
💡 Worth knowing: this same SSL-check habit is worth applying to any online supplement checkout, not just this specific product's.
