Been using the same antiperspirant for 7 years. I have bad allergies and sensitive skin so once I find one that works for me I stick with it. My stockpile I bought last year was finally running out so I bought a new can. Identical packaging, absolutely no difference on the outside. I used it for the first time today and discovered that they added some kind of powerful, harsh fragrance to it which immediately irritated my eyes and nose. Then after a few minutes my armpits broke out in a rash. I’m fucking livid.
This shit right here. So infuriating! I too have incredibly sensitive skin and it is so hard to find stuff that is fragrance free and doesn’t cause my skin to just get angry with me. I feel your pain!
I’ve always liked the idea of corporations having to send a sample to “patent” their products before selling as part of checking the product.
If a company wants to change, repeat with the new product that would require new product packaging that’s obviously different.
Like, food from a restaurant is different, but a packaged product should be consistent within a very small margin of change
