This product gets HOT when curing. It’s marketed as a nonheating gel and it couldn’t be further from the truth. My clients get uncomfortable and fan their hands to try to cope with the heat spike. Otherwise, I love it. I love the purple hue for yellow canceling, I love the consistency, it is so easy to apply. It’s cost effective at less than $1 per gram of product. I wish it didn’t get so hot. I can’t use this on my clients because it shakes their confidence in me and makes them think I am doing something wrong. I educate them on what’s happening and explain that it’s just polymerization but that doesn’t matter to them when their nailbeds are so close to that lava level heat. I can only use this on myself so I’m pretty disappointed. The JinB Coolear is a safer choice. I wanted to love this product but it’s just too hot.
