I love Ameliorate's products, especially because they blend AHAs (lactic acid) with soothing and deeply hydrating actives (such as urea). However, this is not a daily toner for sensitive skin in my opinion: it's more a twice to three times a week liquid exfoliator. It's potent and a little goes a long way if you don't want to feel the sting. I love the results of Ameliorate's formula so I'm still convinced by the product.
