After the second coat, if you can still see your nail through the paint or if the paint looks streaky, do a third coat. Remember, you can only use gel polish with a UV lamp. And if you have gel polish, you canât use it unless you cure it under a UV lightâotherwise, itâll stay tacky and wonât dry.
âThermochromic nail polish takes advantage of leuco dyes, which use either temperature, UV light, or pH to change from one color state to another,â says Christy Rose, founder and product developer for KBShimmer. âLeuco dyes are chemicals that are placed into micro-encapsulations to prevent them from reacting with other chemicals.This is probably what youâre getting when you book a gel mani. Itâs basically a hybrid of gel and regular nail polish thatâs cured and hardened with a UV light, so thereâs zero drying time involved. The word Shellac is actually just the trademarked name from CND, the first company to invent and register this type of polish. Itâs Emujj.
