What I can tell you is that the word "Yunnan Baiyao" is a registered trademark and the font is specially designed; "Aerosol" is directly in italics, and there is no special design. This is the font of Yunnan Baiyao aerosol.
In other words, this change in font does not mean that this medicine is fake. But I can't guarantee whether this medicine is true or not. I can only say that it is generally no problem to buy from formal channels.
