Love this cream
Style: Tolerance Control Soothing Skin Recovery Cream
I absolutely love the Avène Tolerance Control Soothing Skin Recovery Cream — it’s become a sanctuary for my sensitive skin. From the very first application, I noticed how calming and gentle it feels. The texture is rich yet lightweight, absorbing beautifully without any greasiness.
This cream has been a game‑changer for days when my skin feels irritated, reactive, or overwhelmed. It instantly soothes redness and discomfort, and over time my skin feels stronger, more balanced, and resilient. What really stands out is how comfortable and nourished my skin feels all day long — no tightness, no irritation, just pure relief.

Great for Sensitive Skin
Style: Tolerance Control Soothing Skin Recovery Cream
I have very sensitive skin and have tried everything to try and prevent rosacea flairs. I recently came across this brand and I absolutely love this recover cream. I consider this now the holy Grail for Rosacea and sensitive skin. It makes my skin feel hydrated and non-reactive. It is soothing and I just cannot get enough of it. It is pricy but it is worth it to not have my face constantly feeling like its burning or irritated.

Great product for sensitive skin
Style: Tolerance Control Soothing Skin Recovery Cream
I have sensitive skin that is constantly getting irritated by moisturizers/seemingly simple skin care products. I read a few blogs/articles/reviews on different products others have tried for similar issues and this one came up, so I decided to give it a try. It’s nice and light and goes on smoothly. Skin feels moisturized and does not get irritated, so that’s a win! The only reason I took off 1 star is it leaves my skin a bit oily for my liking, but that could just be my skin.
