To ensure no damage to natural nails while enjoying long-lasting results, opt for a quality gel or dip powder system that is easy to apply. Always prepare nails properly by cleaning and buffing them, and avoid excessive filing. When curing, follow warm tips such as using a UV or LED lamp as per the manufacturer's instructions, ensuring even application to prevent uneven curing, and gradually building up layers for a smooth finish. Additionally, remember to hydrate your nails and cuticles post-application to maintain their health.
