The issue is that even "gentle" brands can have irritants depending on your specific triggers - fragrance, essential oils, or even certain ceramides can set off rosacea. Since CeraVe and La Roche-Posay sting for you, you might need something even more stripped back: people with severe rosacea often do better with Vanicream's free & clear line or Cetaphil's fragrance-free options, or honestly just a basic ceramide cream like Eucerin Eczema Relief. Before trying anything new though, have you identified what specifically causes the stinging - is it the texture, certain ingredients you've noticed, or pretty much everything? That'd help narrow down whether you need fewer actives, different humectants, or possibly something prescription-strength from a dermatologist if over-the-counter keeps failing.
