Easy Application Guide:
Achieve salon-quality nails at home with these simple steps:
1. Prepare: Trim, file, and buff your natural nails. Cleanse thoroughly to remove any oils or dust. (IMPORTANT)
2. Base Coat: Apply a thin layer of base coat and cure under an LED/UV lamp for 60 seconds.
3. Apply Gel: Apply the builder gel to the nail, edging closer to the sidewalls.
4. Build Apex: For extensions, place your finger upside down to help the gel form a natural apex. Cure for 60-90 seconds.
5. Shape: File and shape the nail to your desired style. Cleanse the nail.
7. Top Coat: Apply a layer of top coat for a sealed, glossy finish and cure for 60 seconds.
Package Included:
• 1 x Bottle of GELLEN 7-in-1 Builder Nail Gel (15ml / 0.5 fl.oz)
Important Notes:
• This product requires curing under a UV/LED Lamp for 60-120 seconds to harden completely.
• A slightly sticky layer after curing is normal and helps the top coat adhere better.
• For best results, always start with clean, dry nails free of oils and moisture.
