My favourite line reducer

I have tried a few of these serums recently but the Kiehls one is the only one I have tried that seems to work for any length of time, it does not sting or “tingle” like some, or make my skin tight and dry like others, and I know when I apply this serum to my frown lines I know they will be visibly reduced for most of the day which is exactly what I want from a product. I love the Kiehls line and am so pleased they have launched here in South Africa
