Use a good or high end builder gel. Prep like normal, buff, dehydrate, prime. Thin slip layer of builder gel, apply the nail tip, cure, and really focus on blending in the nail tip to your natural nail near the cuticle. And most importantly seal that cuticle with acetone to prevent it from lifting. Also don’t overflow the gel near the cuticle, it’ll lift easier and pop off. Make sure to remind clients to use cuticle oil, keeps the nail bed from drying out and lifting the builder gel.
