When your fave skincare discontinued

So I experience a lot of time And mostly it’s L’Oréal 🙃 My first time is the Hydrafresh from L’Oréal.. that time around 2013/2014 the product became rare and hard to find while i wash really depending on it for my dry skin.. it tooks me try and error for around the next 3 years to finally find the replacement for it (as in my country dry skin products is super rare) And recently it’s happene again.. this time L’Oréal revitalift 3x laser series, I already buy it for mom since 2016 and now It’s rare super rare, even at their official store it’s been gone since months.. I really hate when it happens because we need to do try and error again 🥲 and it’s took time.. no mention with the error that sometimes cause skin damage Like why the brand would discontinue a good product? And dont made a replacement for it? I meant they could launch an improvement product or launch a new product with the same concern, but they dont.. the discontinued it and launch a completely different product concern 🥹 How do you think about it when a brand discontinued ur fave product? And how did you moving on from it? Because it’s always took me years to finally find the replacement 🙃
