Phototherapy gels, also known as UV/LED-curable gels, are advanced formulations that polymerize rapidly upon exposure to UV or LED light. They are widely used in the nail industry for creating durable, high-gloss, and artistic nail enhancements.
High Gloss & Clarity: Delivers a brilliant, salon-quality finish.
Rapid Curing: Significantly reduces service time.
Solvent-Free & Low Irritation: Enhanced user comfort and safety.
Excellent Durability: Provides superior scratch resistance and long-lasting wear.
LED Lamps: Efficient and longer-lasting. Common power ratings: 2W, 4W, 9W, 12W.
Traditional UV Lamps: Broad-spectrum. Common power ratings: 9W, 18W, 36W.
Nail Preparation: Clean and degrease the natural or ABS artificial nail.
Base Coat: Apply primer and cure under a lamp.
Color Gel: Apply two thin layers of color gel, curing each separately.
Top Coat: Apply a sealing layer and cure.
Finishing: Wipe the sticky inhibition layer with alcohol.
Gently buff the surface gloss.
Soak a cotton pad in remover, place on the nail, and wrap with aluminum foil for 15-20 minutes.
Gently scrape off the softened gel.
Apply cuticle oil for nail and skin maintenance.
