Acne Treatments
Summary
Host Greg Foot investigates over-the-counter acne treatments with dermatologist Dr. Emma Wedgworth and skincare app founder Ahana Banerjee. They evaluate the efficacy of key ingredients like benzoyl peroxide, salicylic acid, azelaic acid, and niacinamide, while debunking myths about diet, stress, and natural remedies like tea tree oil. The episode also examines pimple patches and whether higher price points correlate with better results, concluding that while OTC products help mild cases, severe acne often requires prescription medical treatment.
