How long does shipping take for domestic orders?
Standard domestic orders are typically processed within 1-3 business days. Once shipped, delivery usually takes between 3-7 business days depending on your location and the shipping method selected at checkout.
What is your return policy for opened products?
Due to the cosmetic nature of our products and hygiene standards, we cannot accept returns on opened or used items. If you receive a defective or damaged product, please contact our support team within 14 days of delivery for a replacement.
Are KOKOIST products cruelty-free and vegan?
Yes, KOKOIST is proud to be a cruelty-free brand. We do not test our products on animals. Most of our gel colors and systems are also vegan-friendly; please refer to specific product pages for full ingredient lists.
Which LED/UV lamp should I use to cure KOKOIST gels?
For optimal results and a complete cure, we highly recommend using the KOKOIST Infinity Light or Le Blanc Lamp. Our gels are formulated to cure at specific nanometers (365nm and 405nm) to ensure maximum adhesion and shine.
