Are Life-Flasks stacking?

[42]

I often get a damage dot from the mobs which drains my complete life in two seconds. I always activate all my life flask (1-4) in this case these should restore up to 500 life points per second but anyway I always die. I have 1200 life and it should be easy to stop the life drain but no - no chance.

What to do in this situation?

Are all life flask only restore 500 points per second? I never found one that restores more per second.

Dispel that ailment, e.g. with a remove bleed flask ("of staunching" suffix).

You know you can use currency to craft a magic flask, right? Because you can get such modifiers or even increased/instant recovery etc.

Otherwise, life flasks don't really stack, they queue.

There are unique flasks which can help as well: https://pathofexile.fandom.com/wiki/Blood_of_the_Karui

A life flask healing effect stops when the character reaches full life. So if you have a dot effect and you pop several flasks, if one of them makes you go full life it stops working (so the next ones in the queue will heal your full hp char and won't actually heal anything because they'll stop working too).
It's not actually efficientto have a lot of life flasks, Usually you want 2 at most, one with a slow but long regen and hat can regen a lot of life (some can go to more than 1200 hp), and one flask with the less healing and instant recovery mod as a panic button.

What you ultimately want are defencive flasks that automatically remove those dot effects instead of trying to heal the thing.

Thank you all a lot.

You can also find jewels with "Corrupted Blood cannot be inflicted on you" which will make your life easier. You'll still want to carry a bleed flask and other flasks to counteract the damage over time effects you will encounter
