Introduction
For professional eyelash salons, curing lash glue quickly and efficiently is crucial. UV eyelash lamps have revolutionized the beauty industry by providing a faster curing process than traditional air-drying methods. However, not all UV lamps are created equal—especially when it comes to wavelengths.
Two common options are 395nm and 405nm UV lamps, but which one is better for lash adhesive curing? Many beauty professionals struggle to decide between these wavelengths, unsure of their effectiveness, safety, and curing speed.
This article breaks down the key differences between 395nm and 405nm UV light, helping you choose the right lamp for your salon.
395nm vs 405nm UV Eyelash Lamps: The Key Difference
The main difference between 395nm and 405nm UV eyelash lamps lies in curing efficiency and safety. While both wavelengths fall in the UVA spectrum, 405nm provides faster and more even curing for lash adhesives. It is the industry standard for UV lash glue curing and offers better penetration without excessive heat. In contrast, 395nm is less effective for curing and is commonly used for other UV applications, such as fluorescence detection. For professional eyelash salons, 405nm is the superior choice.
Now, let’s take a deeper look at how each wavelength works and why 405nm is the best option for beauty professionals.
What Is the Best Wavelength for UV Curing?
The wavelength of UV light determines how well it interacts with adhesives and how fast the curing process happens.
- 365nm UV light is deep-penetrating but mainly used for industrial resin curing.
- 395nm UV light falls in the UVA range but is less effective for lash glue.
- 405nm UV light is the optimal choice for eyelash glue because it:
- Cures evenly and quickly.
- Produces less heat, reducing irritation for clients.
- Is safe for salon use with the right protective measures.
Most professional lash glue manufacturers recommend 405nm because it provides the best balance of curing speed and safety.

What Is the 395nm UV Light Used For?
Although 395nm UV light falls within the UVA spectrum, it is not ideal for curing lash glue. Instead, it is commonly used for:
✅ Fluorescence detection (antiques, forensic analysis).
✅ Basic UV adhesive curing, but slower than 405nm.
✅ Nail polish curing, though 405nm is also used in nail salons.
Why Should Beauty Professionals Avoid 395nm?
- It is not as effective as 405nm for curing lash glue.
- It may cause uneven curing, leading to weaker lash extensions.
- It takes longer to cure, reducing client efficiency in salons.
For beauty professionals focused on quality and efficiency, 405nm UV lamps are the clear winner.
Is 365nm or 395nm Better for Curing UV Glue?
Some lash artists compare 365nm, 395nm, and 405nm UV lights for curing glue. Here’s how they stack up:
| Wavelength | Best For | Curing Speed | Suitability for Lash Glue |
|---|---|---|---|
| 365nm | Industrial resins | Deep penetration, Fast | Too high intensity, too much heat |
| 395nm | Fluorescence detection, minor curing | Medium speed | Common wavelength, medium heat |
| 405nm | Lash glue, nail curing | Fast & even curing | ✅ Visible light band, low heat |
Since lash glue is different from resin, 405nm provides the best performance in beauty applications.
Is 405nm LED UV Light Safe?
Many salon owners worry about UV exposure and client safety when using UV lash lamps. Here’s why 405nm is safe for professional use:
- Lower UV risk: Unlike UVB or UVC, 405nm UV light does not cause severe skin damage.
- Minimal heat: Unlike 395nm, 405nm produces less heat, reducing eye discomfort for clients.
- Protective measures: Using protective eyewear ensures full safety during lash procedures.
