Demystifying the Difference Between BIAB Nails and Gel-in-a-Jar Nails

In the realm of nail enhancements, two popular techniques have emerged as frontrunners: BIAB (Builder in a Bottle) nails and Gel-in-a-Jar nails. While both methods offer strength, durability, and aesthetic appeal, they vary significantly in their application processes, composition, and overall performance. In this article, we'll unravel the disparities between BIAB nails and Gel-in-a-Jar nails, shedding light on their unique features, application methods, and pros and cons.


Understanding BIAB Nails: BIAB nails, also known as Builder in a Bottle nails, revolutionized the nail industry by offering a convenient all-in-one solution for creating strong and durable nail enhancements. This technique involves the application of a thick, builder gel directly onto the natural nail to provide structure, strength, and a flawless finish.

Application Process:

  1. Preparation: The natural nails are prepared by cleaning, shaping, and lightly buffing to create a smooth surface.

  2. Base Layer: A base layer of BIAB gel is applied to the natural nail and cured under a UV or LED lamp.

  3. Building Layers: Additional layers of BIAB gel are applied to build thickness and strength as desired. Each layer is cured under the lamp before the next application.

  4. Finishing: Once the desired thickness is achieved, the nails are filed, shaped, and buffed to perfection. A glossy topcoat may be applied for a polished finish.


  • Exceptional strength and durability akin to acrylic nails.

  • Lightweight and flexible.

  • Minimal filing of the natural nail required.

  • Versatile – suitable for overlays or extensions.


  • Requires UV or LED lamp for curing.

  • Initial learning curve for application.

  • Removal process may involve soaking in acetone.


Exploring Gel-in-a-Jar Nails: Gel-in-a-Jar nails offer a convenient and versatile approach to nail enhancements, providing a pre-made gel formula that can be applied directly onto the natural nail or used for extensions. This method eliminates the need for mixing different products and allows for quick and easy application.

Application Process:

  1. Preparation: The natural nails are prepped by cleaning, shaping, and applying a dehydrating agent and primer for better adhesion.

  2. Application: Gel from the jar is scooped out and applied to the natural nail or nail tip, forming the desired shape and length.

  3. Curing: The applied gel is cured under a UV or LED lamp to harden and set.

  4. Finishing: Once cured, the nails are filed, shaped, and buffed to refine the shape and smooth out any imperfections. A topcoat may be applied for added shine and protection.


  • Convenient pre-made gel formula.

  • Quick and easy application process.

  • Can be used for overlays or extensions.

  • Versatile – available in various colors and finishes.


  • May not offer the same level of strength as BIAB nails.

  • Limited control over the gel consistency and formula.

  • Requires UV or LED lamp for curing.


Both BIAB nails and Gel-in-a-Jar nails offer distinct advantages and cater to different preferences and needs. While BIAB nails focus on providing superior strength and durability with a customizable application process, Gel-in-a-Jar nails offer convenience and versatility with pre-made gel formulas. Ultimately, the choice between the two techniques depends on individual preferences, desired outcomes, and lifestyle considerations. Whether you opt for the robustness of BIAB or the convenience of Gel-in-a-Jar, both options can help you achieve stunning and long-lasting nail enhancements.
