The answer is, no. It is not harmful, ONLY if the blue liquid contains MMA (Methyl Metacrylate).
----------
The priciest product, if applying acrylic nails, is the blue liquid. In order to keep the price of the services low in a few nail salons they buy really cheap liquid, which contains MMA...
☣️ It is extremely toxic, can be irritating on the skin and can cause severe allergic reactions! Also has a really strong smell that can physically affect you (tightness in your throat and chest, tingling in your fingers, lightheadedness, dizziness, etc.)
It dries much harder than regular liquid+acrylic. (Trust me, I've had to remove a few of these kind of acrylics, and I was sweating at the end.)
✔️I use MMA-free liquid ONLY!
It contains Ethyl Methacrylate, a product which is far less likely to cause an allergic reaction, and it is not banned by FDA (Food and Drug Administration).
"The CIR (Cosmetic Review Board) has tested the more commonly used EMA liquid and found it "safe enough to be used by the consumer" but recommend it to be used by trained professionals."
It is pricier, but much safer!
✔️Don't ditch acrylic, just make sure that your technician uses MMA-free liquid only! Be mindful of the nail salon that you choose. It might be cheap, but it can be dangerous!
Do your research, always.
More info about MMA
"•The FDA, as far back as early 1970's, has stated, and still states, that MMA is a poisonous and deleterious substance and should not be used in liquid acrylic monomer for nail products. •MMA is not recommended for use in acrylic nail products because it is much too hard, and can tear the nail off the finger easily. • It is also solvent resistant, which makes it very difficult to remove. It takes a long time to remove MMA when soaking in acetone. • Many technicians damage the nail plate when prepping for MMA, since that product needs grooves in the nail in order to stick well. ‼️ A technician should always protect and preserve the natural nail under any enhancement product. • And, finally, MMA should not be used in nail products because the FDA has determined that it is not safe for that purpose. •When a nail enhancement of MMA is banged or knocked, it has little to no flexibility and will break severely, often taking the nail plate with it. EMA is formulated to be flexible, the enhancement will break or crack, sometimes the nail will break off, but will not usually damage the nail plate."
MMA VS EMA application
----------------------------------- *Although EMA is safe to use, some people can have a reaction to it. But it can be also true to any gels, gel polishes, prepping liquids, soaps etc. If you experience any unusual signs, contact your technician immediately.
