In this special episode, the full Lash Apothecary team—Curtis, Olivia, Anne, and Carly—come together to share the untold story of how Lash Apothecary began and how the Opal LED UV Lash System came to life.
We dive into:
The personal journeys that led each of us together to make Lash Apothecary what it is now
The series of events that led to the idea for the Opal system
The challenges of creating something brand new for lash artists
How Lash Apothecary is here to change the industry for the better
Whether you’re a lash artist curious about light-curing technology, or just want to hear the behind-the-scenes of building a brand from scratch, this episode will give you an inside look at the heart of Lash Apothecary!!
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
Is LED UV lash glue the same as gel nail polish? A lot of lash artists wonder if light-cured adhesives are just like UV resin or gel polish — and today we’re breaking it all down.
In this episode, we dive into:
✨ What resin really means in chemistry
✨ The big ingredient differences between gel nail polishes and LED lash adhesives
✨ How safety and biocompatibility set lash adhesives apart
Whether you’ve ever questioned if lash glue is “just like gel polish” or you’ve seen UV resin crafting products and wondered how they compare — this episode clears up the confusion once and for all.
Are oils really ruining your retention — or have we all been lied to?
In this episode of Lash Science, Carly and Olivia are joined by cosmetic chemist, Michael Becker, to finally get to the bottom of one of the most misunderstood topics in lash care: OIL.
We cover everything from:
How oils actually interact with lash adhesives (traditional and light-cured)
Which oils are actually a problem… and which ones are totally fine
Whether light-cured adhesives hold up better against oil-based products
Common myths about "oil-free" aftercare
Why not all cleansers and balms are created equal
This is the episode every lash artist and educator needs to hear!
In this episode of Lash Science, we’re diving deep into the Opal LED UV Lash System from Lash Apothecary — the game-changing technology that’s rewriting the rules of lash extensions.
We break down how the Opal light is built, the rigorous safety measures behind it, and why Lash Apothecary goes above and beyond to ensure it’s not just safe... but the safest option on the market!!!
Then we get into the star of the show: the Opal Adhesive. We discuss the chemical formulation, why each ingredient was chosen, and how it delivers:
Better retention that stands the test of time
A truly hypoallergenic formula that supports sensitive clients
300x less fumes for a healthier work environment
Freedom from humidity and temperature stress so you can focus on artistry, not your glue timer
Whether you’re a beginner or a seasoned lash artist, Opal changes the way you work; giving you the time, control, and confidence to create your best sets ever.

Is UV light a public health threat… or have we been scared into sunlight phobia?
In this episode, we dive into the "Great Solar Debate", breaking down how sunburns, tanning, and skin cancer actually happen, and whether the lash industry (and the world) have misunderstood UV exposure altogether.
We cover what UVA and UVB really do to your skin, how the electromagnetic spectrum plays a role, and the difference between damage, and disease. We also talk about how much sun exposure is actually healthy, and why a little UV isn’t just safe—it’s essential!!!!
Then, we zoom in on LED UV lash lamps, like Opal, and explain exactly why they cannot cause sunburns, tans, premature aging, or cancer—despite the fear-mongering going around the lash industry...........
What if UV wasn’t the villain, it was just misunderstood? Listen now to find out.
In this episode, we dive deep into one of the most overlooked but essential tools in lash artistry: saline solution!!
We break down the differences between saline, contact solution, and multi-purpose solution, and explain why only saline belongs in your lash services. From protecting the delicate tear film to reducing irritation, preventing sensitivities, and boosting retention, we cover it all.
We also tackle common myths in the lash industry, like whether saline makes lashes crunchy, ruins retention, or is “just expensive water” — and explain why micellar water or contact solution are NOT safe alternatives.
By the end of this episode, you’ll understand how saline can elevate your lash services, protect client eye health, and position you as an advanced, health-conscious artist!
Learn how to level up your lash game with science-backed insights and practical tips that your clients (and their eyes) will thank you for.
In this special episode, Carly and Olivia are joined by optometrists Dr. Gurleen Dhanoa and Dr. Aysha Chaudhry from @eyestheticsofficial for an in-depth conversation about ocular health, lash extensions, and why hypochlorous acid (HOCl) deserves a place in every lash artist’s routine!
We discuss how they became involved in the lash industry, what healthy lash extensions and proper ocular hygiene look like from an eye doctor’s perspective, and the best practices they wish more lash artists would follow. The episode then dives into all things HOCl: what it is, where it comes from, how it can benefit both lash artists and clients, and how to properly store and apply it. They also cover practical topics like HOCl concentration, product shelf life, packaging differences, client aftercare, and even whether artists should consider charging for HOCl treatments as an add-on or just include it in every service.
If you’ve ever wondered how to elevate your lash services with medical-grade eye care practices, this episode is packed with expert insights you won’t want to miss.

Think you know how to patch test for lash extensions? Think again. In this episode, we're breaking down the correct way to perform a patch test — using one eye only, applying 10–15 lashes in a single section, and replicating your full service exactly — whether you’re using traditional or light-cured adhesive.
We explain why this method matters, what subtle symptoms to watch for, and how even the smallest reaction can signal something bigger. You’ll also learn what to do if your client reacts, and how patch testing fits into a responsible lash artist’s routine — especially in today’s world of rising sensitivities.

Let’s shine a light on the truth 👁️💡
In this episode of The DM Diaries, we’re spilling the tea on a recent encounter with a high-profile lash influencer who had some not-so-nice things to say about UV lash extensions.
