    Please give us a little more information about your Ingredients and % of it. For example, it can be caused by Potassium sorbate in a higher concentration or ……. there are so many reasons like too much or the wrong Surfactaned for a wash of.

    Course AHA itself is able to promote stinging on the skin as well as lactic acid. depending on the ph of the product 3 % seems very sour to me.

        i would suspect your ph is very acidic with this formulation. for how long do you let it stay on the skin before rinsing it off?

        I guess if you feel stinging it already exfoliates all the dead skin and you are starting to exfoliate the skin that is intact.

        For the ingredients, some people react to Phenoxyethanol and Propandiol but I would bet more on the time and acidic train than on that being the reason.

    I think that the area around the nose is usuallly thiner or if you have a cold or something and blow your nose often it can get easily irritated. (?)Or you just have more sensitive area around the nose. Has anyone else tried the product? If so, did they experience the same?

    What is the final pH of the product?

    You should have an anti inflammatory ingredient in this formula, like Bisabolol at 1% or so. Add a superfatting material like Polysorbate 20. Increase pH with its conjugate base to about pH 4. It should stop the stinging and help.
