A chemical burn?

Question: In Doug Schoon’s books, he talks about ph levels in sơn gel. He says that, because there is no water in gel polishes, there is no ph. I saw an article in the blog, there was a picture of a chemical burn from a rubber căn cứ. I wanted to ask, if there is no ph in gel đánh bóng, from what can a chemical burn be caused?

Answer: Doug Schoon is correct with regard to pH.
Firstly, I must explain that a ‘rubber base’ is not a product that is a problem. What is the problem is any base that has a high % of chất gây dị ứng OR it is applied in a lớp phủ that is too thick to properly sự chữa bệnh (of course the correct Đèn UV is crucial).
‘Chemical burn’ can be used as a general description used for a chemical that, when ‘over-exposed’ can cause redness, irritation, skin damage, etc. 
Obviously, axit or alkalis can cause a ‘burn’ that is often associated with heat as the results are similar.
It is a descriptive term that, while not necessarily totally accurate, does help many to understand that phơi sáng quá mức can create a similar effect on the skin.
