In Part 2, we go deeper into what those “formaldehyde fumes” actually mean for your body — and why this conversation is occupational health literacy, not fear marketing.
We cover:
the full list of common symptoms artists and clients experience
how repeated exposure can sensitize the body, leading to stronger reactions over time
does exposure cause allergic contact dermatitis, respiratory sensitization, and irritant responses
and we fact-check a popular Instagram carousel that downplays the risks — line by line
This one is bold, honest, and very spicy!!🌶️🔥
