    34. Cold Weather and Lash Allergies: Is There a Connection?

    In this episode, we explore the question: is there a real connection between cold weather and lash allergies? We walk through a peer-reviewed PubMed study together (reading and interpreting the abstract in real time) and break down what it reveals about how cold, dry environments impact the skin barrier — especially the delicate eyelid area. We then connect that science to what lash artists see in the treatment room: seasonal increases in irritation, sensitivities, and allergic-type reactions — and why a compromised eyelid skin barrier can increase a client’s risk of reacting to products they previously tolerated. If you’re a lash artist who wants to understand the why behind seasonal reactions (and not just how to manage them), this episode will give you a clearer, evidence-based framework for protecting your clients’ skin, eyes, and long-term lash health.   Source: https://pubmed.ncbi.nlm.nih.gov/26449379/

    28. The TPO Ban Explained: What the EU Cosmetic Ban Means for Nail Techs & Lash Artists

    The EU (European Union) has officially banned TPO (Trimethylbenzoyl Diphenylphosphine Oxide) in all cosmetic products starting September 1, 2025. This includes gel nail polish and LED UV lash adhesives — but why did this happen, what does it mean for beauty professionals, and should you be worried? In this episode, we break down: What TPO is and how it’s used as a photo initiator in beauty products Why it was originally considered safe, and what changed after rat studies in 2021 The difference between cosmetic use (ban) and dental use (still allowed) How much TPO was actually given to test animals (hint: way more than real salon exposure) What this means for nail techs, lash artists, and salon owners — including what to do with old stock The rise of “TPO-free” products and whether TPO-L is a safe replacement   This is not just a nail industry issue — it affects all cosmetic professionals, including lash artists using LED UV curing systems.   If you’re a beauty pro trying to make sense of the headlines (New York Post, People, Allure, The Times), this episode gives you the science, context, and business impact you need to stay ahead!!   Common Names on MSDS/SDS Sheets: Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide CAS #75980-60-8 EC/EINECS #278-355-8
