In this episode of Aesthetics Today, TV Beauty Expert, Skin Wellness Guru and Podcast Host, Gabrielle Richens speaks with special guest Dr Theresa Callaghan, biochemist, author, and long-standing cosmetic claims expert, about what really sits behind skincare promises, aesthetic treatments, and the modern beauty industry.

Dr Callaghan shares her journey from academic research into global beauty brands, reflecting on how skincare once moved slowly and carefully, and why the pressure to innovate has increasingly collided with scientific integrity and regulation. Together, they explore why strong cosmetic claims require robust evidence, how “cheap” or rushed studies erode trust, and why skin barrier health underpins almost everything we do to the skin.

The conversation also addresses some of the industry’s most uncomfortable topics: misinformation around “toxins” and clean beauty, the risks of poorly regulated aesthetic procedures, and growing concern over children adopting adult skincare routines.

Dr Callaghan offers a grounded, evidence-based perspective on ageing, challenging the idea that it is something to fight. She argues for a more respectful, less anxiety-driven relationship with skin and appearance.

Thoughtful and unfiltered, this episode invites listeners to slow down, question the narratives they are sold, and approach skincare and aesthetics with realism, responsibility and care.
