One of the most common questions we receive is:
"Should I choose sachets or bottles?" (referring to our fave InLei® lash lift/brow lamination products).
The truth is, neither option is inherently better than the other.
The right choice depends entirely on your business model, appointment volume, and how you like to work.
Whether you're offering Lash Filler or Brow Bomber services, understanding the benefits of each format can help you maximize product performance, reduce waste, and improve profitability.
Let's break it down.
First Things First: The Formula Is Exactly the Same
Before we dive into the differences, it's important to clarify one thing:
The solutions inside InLei® sachets and bottles are identical.
You're getting the same Italian-made formulas, the same rigorous quality control, and the same beautiful results.
Every batch undergoes multiple rounds of testing for:
- Efficacy
- Safety
- Stability
- Quality
The only difference is the packaging and how that packaging fits into your workflow. Sachets are quadruple-lined, and bottles are glass... ensuring maximum freshness and reducing risk of oxidisation.
The Case for Sachets
Sachets are often the preferred choice for busy salons, training academies, and teams with multiple artists performing treatments.
Why?
Because they provide consistency.
Each sachet contains a pre-measured amount of product, meaning every artist is working with the same quantity and the same fresh solution every time.
This can be particularly helpful when multiple technicians are performing treatments within the same salon.
Benefits of Sachets
- ✔ Fresh product
- ✔ 1-3 applications per sachet (up to two for Brow Bomber, up to three for Lash Filler)
- ✔ Excellent hygiene and sanitation
- ✔ Easy to distribute across multiple staff members + very convienient
- ✔ Ideal for training environments
- ✔ Up to 1 week to use the product after opening
- For salon owners, sachets also make inventory/backbar management incredibly straightforward.
You know exactly how many treatments remain and exactly how much product is being used.
Treatment Yield
InLei® Lash Filler Sachets
-
Up to approximately 27 treatments
InLei® Brow Bomber Sachets
-
Up to approximately 18 treatments
If your salon has multiple artists performing lash lifts or brow laminations daily, sachets often provide the simplest and most predictable workflow.
The Case for Bottles
Bottles are designed for artists who perform treatments frequently and want maximum efficiency.
If you're fully booked with lash lifts or brow laminations every week, bottles may offer the best value for your business.
Unlike traditional packaging, InLei® bottles feature an airless pump system.
This helps protect the product from unnecessary air exposure while allowing you to dispense only the amount you need.
The result?
Less waste.
More treatments.
Greater efficiency.
Benefits of Bottles
- ✔ More treatments per package
- ✔ Cost-efficient for high-volume artists
- ✔ Airless pump technology
- ✔ Quick and convenient between appointments
- ✔ Minimal product waste
- ✔ Ideal for experienced artists with consistent booking volume
Treatment Yield
InLei® Lash Filler Bottles
-
Up to approximately 35 treatments
InLei® Brow Bomber Bottles
-
Up to approximately 30 treatments
For artists performing multiple treatments every week, those additional treatments can make a significant difference over time.
How Often Are You Performing Treatments?
This is usually the deciding factor.
If You Perform 1–2 Treatments Per Week
We typically recommend sachets.
Because you're opening a fresh solution every time, you don't need to worry about unused product sitting between appointments.
Sachets provide flexibility while minimizing waste.
They're also a fantastic option if you're:
-
Newly certified
-
Building your clientele
-
Offering lash lifts or brow laminations as a secondary service
If You Perform Treatments Daily
We typically recommend bottles.
If you're regularly reaching for Lash Filler or Brow Bomber throughout the week, bottles offer excellent value and convenience.
The increased treatment yield means lower cost per service while allowing you to move efficiently between appointments.
They're particularly popular among:
- Established lash artists
- Brow specialists
- High-volume technicians
- Busy salons with consistent bookings
A Different Way to Think About It
Rather than asking:
"Which one is better?"
Ask yourself:
"Which one matches the way I work?"
Choose sachets if you value:
✨ Simplicity across multiple staff members
✨ Flexibility in amount of services
✨ Minimal Waste
Choose bottles if you value:
✨ Maximum treatment yield
✨ Cost efficiency
✨ High-volume service schedules
Our Recommendation
If you're just starting out or performing lash lifts and brow laminations occasionally, sachets are often the smartest choice.
If you're fully booked and offering these services regularly, bottles will typically provide greater efficiency and better value over time.
The good news?
Whichever option you choose, you're still getting the same trusted InLei® formulas, developed and manufactured in Italy and designed to create beautiful, consistent results while supporting the health and integrity of the natural hair.
The only question left is:
Which format best suits your business?
