I have the LED shellac lamp and follow the usual instructions. However yesterday I doubled the time for each application. When I wiped with isopropyl alcohol some of the nails Lost colour on the sides. Can you advise why this happened?
You can overture in two ways 1. too long an exposure and 2. curing too fast which results in excessive heat being released and heat spikes. According to Doug Schoon and Jim McConnell, you can overcure gel, but it takes a lot to do it.
So say for instance your doing a set of gel extensions, the first nail might essentially end up being cured 5 times? And that’s before you’ve added layers of colours and top coat? So how would you know if you’ve under or over cured your product?
This was just posted on Doug Schoon's FB page:
Received an interesting question today, that I’d like to share.
Question: "I’m using the correct lamp for my UV gel, but having a problem with the thumbs properly curing. Can I move the thumb closer to the led bulb and cure a little longer than the 30 seconds recommended? I know this can release too much heat, but can this cause other problems?"
As this NT points out, the risks of “over curing” is excessive heat spikes- which can lead to onycholysis and nail bed infections.
When NT’s are careful to avoid heat spikes, curing longer under the UV nail lamp is NOT likely to cause other negative issues.
Many are concerned about over curing, when really they should be worried about “under curing”, which is one of the most important problems in the nail industry. This problem can lead to serious allergic reactions for techs, killing nail careers and driving many out of the business due to their adverse skin reactions to products.
As I explain in my books and videos series, “under curing” can causes many to become allergic to nail products, so this must be avoided… yet it commonly happens because many are unaware of the potential for serious allergies to occur. What you don’t know CAN harm you. Learn more and protect yourself.
