GELLEN Builder Gel Kit Nail Extension 4-Color Set 15ml — Hard Gel, Glossy Finish

GELLEN Builder Gel Kit is a four-color professional nail extension set with 15ml hard builder gels designed to sculpt strong, glossy extensions at home.

If you want durable, salon-style nail extensions without acrylic dust or tips, this kit gives you four coordinating shades—nude, baby pink, naked purple, and rose brown—formulated as hard builder gel. Each 15ml jar cures under a UV/LED lamp to form a robust, slightly flexible overlay that supports length and resists chipping. The kit contains only builder gel (no base/top coats or lamps), so you’ll pair it with your preferred prep and finish products and a slip solution for easy shaping.

How quickly can I build and cure a nail extension with this kit?

Builder gel layers cure rapidly under a suitable lamp, making multi-layer sculpting efficient. Expect 1–2 minutes of curing per thin layer depending on lamp power and gel thickness. Thin, controlled layers build structure faster and reduce heat spikes during cure.

• Cure each thin layer 1–2 minutes under a recommended UV/LED lamp.
• Use slip solution to shape before final curing.
• Apply multiple thin layers rather than one thick coat.
• Finish with your preferred top coat for extra shine and protection.

What prep and tools do I need to get reliable results?

Good prep ensures adhesion and a long-lasting finish. Clean, dehydrate, and lightly buff the natural nail; use a primer if you typically have weak adhesion. Because this kit contains only builder gels, you’ll need a lamp, slip solution, and optional base/top coat to complete the system.

• UV/LED lamp rated for gel curing.
• Slip solution for sculpting and smoothing the gel.
• Basic prep kit: file, buffer, cuticle pusher, alcohol wipes.
• Optional: base coat, top coat, and primer for enhanced longevity.

How durable and flexible are the finished extensions?

After proper curing, the GELLEN builder gels harden into a tough yet slightly flexible shell that protects natural nails and supports added length. With correct application and maintenance, the overlay can last three weeks or longer before visible wear, resisting chips and lifting under normal daily use.

• Becomes hard gel after curing for strength and impact resistance.
• Formulated with flexibility to reduce cracking on longer extensions.
• Recommended thin layering prevents brittleness and heat during curing.
• Eco-friendlier, low-odor formula—non-toxic ingredients listed by the brand.

Are there safety notes or common application tips I should follow?

Follow the included directions and perform a skin patch test before full use to check for sensitivity. Avoid direct skin contact during application, and stop use if irritation occurs. The kit assumes familiarity with gel systems; beginners should practice shaping on tips or practice nails first.

• Always perform a skin test for allergic reactions before regular use.
• Thin coats cure more evenly and reduce the chance of lifting.
• Keep a slip solution handy to manage stickiness while shaping.
• Contact GELLEN customer service for product questions or issues.
