Wonderful recovery Cream
Style: Tolerance Control Soothing Skin Recovery Cream
The cream is very soothing on the skin, it is all that it claims to do. After a couple of uses, my skin cleared up of all the dryness and redness. It is gentle and effective on the skin. Its very good value for money. For anyone with sensitive skin its very beneficial. I will recommend it.

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.
