I bought mine on 01/12/2025 is it still good I have a lot left ?

I have not researched this so this is only my personal opinion as an almost-40-year-old but I certainly use my products for a long time, especially if they are expensive! I have looked at the ingredients and I don’t *think* there is anything in this that is prone to going bad quickly, so I think you’re fine to still be using it!
