How to avoid peeling off easily? 1.Before applying, please ensure your nails are completely dry, clean and oil-free, which will keep the gel longer. 2.Recommend to use the same brand base and top coat. 3.Don't apply too thick gel polish. It is necessary that every layer is thin and smooth. Thinner means stronger. 4.Don't apply gel on the skin or cuticle. Cap the nail free edge for each layer. 5.The curing time depends not only on the type of nail polish, but also on the type of nail lamp.
