Is there really a monomer that can be used with any acrylic system?

February 21, 2012 | Bookmark +

I have noticed lately that there are monomers on the market that claim to be universal. Is there really a monomer that can be used with any acrylic system and have the product cure to the durability it should?


Liquid-and-powder systems are based on two different components that must be properly matched and mixed at the correct ratio in order to achieve the desired results. Since there are so many different types of powders available, and these powders contain different levels of initiators and other additives, it is impossible to develop a monomer liquid that works with any polymer powder. Claims of a “universal” acrylic liquid are marketing claims and not substantiated by the scientific facts. Using the incorrect combination of liquid and powder and/or using these at incorrect ratios are leading causes for service breakdown and adverse skin reactions. All products should be used properly and in accordance with the manufacturer’s instructions. Using the incorrect polymer powder with a monomer liquid would not be considered proper use.

What’s the cause of the pinkish-red oval area on the pad of my client’s toes?

I have a client who has a recurring problem with her fourth toes during the winter months. Both of her “ring finger” toes develop a pinkish-red oval area on the pad. Then a month later, when I see her again, the skin has become dry and hard like a callus, with the layers of skin peeling away to reveal a deeper, dark epicenter.  It’s extremely painful for her and, needless to say, we do not touch it. But it clears up in the summer when she’s wearing open-toed sandals, so I suspect it has to be due to the boots she wears in the winter. Plus she never puts lotion on her feet or uses a foot file in between visits. What do you think causes this?

What are the big white spots on my natural-nail client’s nails?

I have a client who has been with me for about two years. She used to wear acrylic nails but has been a natural nail client for eight months or so. She has these white spots on her nails — big spots that are dry, but not flaky, right in the middle of the nail. I did try to buff them lightly but they do not come off or grow off. I had a new client come in last week who had the same on her toenails. She said it started after she had a pedicure done at another salon. Can you help?
