Hi Julia Kristina😊
Thank you for your question✨
When I look, I find that according to Depend, you should not mix products between the Gel iQ and Gel Builder systems. Gel Builder requires special solutions for building materials and base/top coats, as well as its own lamp and removal method. Therefore, it is recommended that you stick to the same system throughout the treatment for the best results and safety.
The difference between Gel Builder and Gel iQ from Depend:
Gel iQ
→ A gel polish system for color and shine
→ Suitable for natural nails
→ Lasts up to 14 days
→ Easy to apply and remove with remover
Gel Builder
→ A building system to strengthen or extend the nails
→ Provides a more durable and resilient surface
→ Lasts up to 3 weeks
→ Requires special products and method for removal
Hope the answer can be helpful for you 💅🏼
Wishing you a super nice day🌞
