OPI Gelcolor: OPI Gelcolor nail polish, launched in October 2011, offers an application similar to that of a traditional nail polish, but imparts an exceptionally glossy finish that can last up to two weeks. Application is simple: simply apply the gel like a conventional nail polish and catalyze it under a UV or LED lamp for the specified time.

How to use OPI Gelcolor:
The Gelcolor application process is similar to that of other gel polishes. Here are the steps to follow:

Preparation:
1. Push back cuticles with an orange wood stick for a clean application.
2. Shape your nails to your style using a natural nail file (150 grit or more).
3. Gently prepare the natural nail by removing shine with a buffer, creating a slightly rough surface.
4. Remove oils and dust with OPI Gelcolor nail cleaner.

Application:
5. Mix the contents by rolling the Gelcolor bottle between your hands.
6. Apply a thin, even coat of Gelcolor Base to the nail.
7. Catalyze for 10 seconds under LED light or 1 minute under UV light. The layer will remain slightly sticky, which is normal.
8. Apply a thin, even coat of Gelcolor color to the nail, sealing the edges and avoiding the skin. Remove any excess before catalyzing.
9. Catalyze for 20 seconds under LED light or 2 minutes under UV light.
10. Apply a second coat of Gelcolor to the nail.
11. Catalyze for 20 seconds under LED light or 2 minutes under UV light.
12. Apply a thin, even coat of Gelcolor Top Coat to the nail for high shine and protection of the lower layers. Seal edges.
13. Catalyze for 20 seconds under LED light or 2 minutes under UV light.

Finalize:
14. Use a generous amount of 99% alcohol or gel cleanser with a lint-free pad to remove any sticky residue from the nail, revealing a perfect finish.
