Thank you for these videos. For me, there is a portion missing from this video and that is showing what a fully cured sample looks like in the isopropyl example. Also showing how to do the thermal test (and what the results look like for under cured and cured).

Rewatching to revise the golden nuggets of information here. ♥️ Thank you LE and Liz for all you've done for techs all over the world.

So, what are the parameters of the difference considered to be okay or cured enough.

Grateful for this. So many people are buying home kits, and I worry about the potential dangers. The problem is magnified by the number of "professionals" that fail to use proper techniques, and all the DIY'ers on social media who have no clue. I think there should be more transparency from manufacturers: I remember when I first got into gel products, lamps weren't even labeled with wattage.

Looking forward to this

Love this information. Thank you for sharing 🤩😘👏

I love it. Thank you so much for sharing

Love Liz 😘

This is awesome ! Jim you’re dope af man

I was wondering if there's a such as over-curing because I always make sure to go longer in the lamp. I hope you cover that in this episode😊

The problem I had testing for weight was that for a realistic application, even on a form much larger than a fingernail, the weight was less than I could realistically compare with a 0.01 gram precision scale, at about 0.08g, and that was with two coats.

Hi Jim & Liz, thanks so much for these videos. could you please give links for the equipment you have used in these experiments?

I have another question, one I have been thinking about for quite a while.

hello and thank you for useful videos. I have a question about base coat. how can you measure the adhesion to the nail surface and its durability on the nail?

Thank you so much for helping to answer the question as to whether a particular gel is being properly cured by a particular lamp! I personally am already allergic to an ingredient commonly found in regular nail polish (TSFR) so want to avoid any potential allergy to a gel polish ingredient. I really want to try the test whereby you soak it in isopropyl alcohol and weigh it before and after drying. But my question is at what percentage weight loss would you say the product has not been properly cured? For example, is it still considered properly cured if there was a 5% or 10% or 25% weight loss?

Hi Jim, I don’t know if you’ll see this but I wondered if you could help me clear something up. I look at ingredients lists for gel polish and whilst they don’t exclusively say they’re HEMA free, I also don’t see it or 2-Hydroxyethyl Methacrylate in the ingredients list. Does this mean it is HEMA Free even though the company haven’t seemed to declare it? Thank you!

Do you have the chemist corner information for reading? Would be really interested.

Thank you so much for this tutorial! I did it immediately I was so excited 😆

Thank you Jim and Liz! Do you have a video on how much gel monomers can penetrate different materials? I have seen studies where HEMA can go through nitrile gloves, so can people who have allergies protect themselves? I DIY nails at home and can't switch to gel polish until I know if the pads used to wipe the inhibition layer and now contain uncured gel can be disposed of safely. Can gel monomers penetrate through garbage bags? PET plastic? LDPE ziploc bags? And would this be considered hazardous waste as the bottles of polish are hazardous waste?

היי אני עובדת עם לייט אלגנט ומאז שעברתי לעבוד עם לייט, אין לי אלרגיה, סבלתי מאלרגיה שנים ומאז שאני עובדת עם לייט, אני מאוד מאושרת, תודה רבה לכם ולג'ימי בפרט שהוא הכין לנו חומר מעולה :-)
