You will absolutely LOVE your nails while you are wearing Gel Polish and I expect your manicure to last for at least 14 days as long as you give them good care and attention during that time.
You should protect your nails by wearing gloves when doing jobs like household cleaning and gardening, hobbies that are rough on your hands or using harsh chemical products. Smoking may yellow some of the paler colours e.g. Cityscape
Be careful when using sun tan oils, suncream or insect repellent solutions as many of these products contain solvent oils which will cause major damage to the Gel Polish Colour Coat- e.g. DEET will be listed as an ingredient in some suncreams- avoid where possible and rinse off nails immediately to prevent as much damage as possible.
Some of the more delicate colours can fade somewhat if one is in chlorinated water followed by excessive sun (remember that chlorine is a bleach and sun intensifies the bleaching action). Dry your hands and nails after swimming (rinse with fresh water if possible) and before sunbathing to minimise any colour fading.
It is recommended you use a Cuticle Oil twice a day (especially at night before going to bed) to replace lost moisture to your skin and nails. Also beneficial is the use of any hand and body lotion daily. Gel Polish is porous so the nail bed will continue to be hydrated while manicured.
Maintaining this aftercare will substantially prolong the life of your manicure and keep your natural nails and the skin surrounding them healthy, moisturised and flexible.
