Hi I have been using the authentic Stalder products: Papaya Kojic Acid Whitening Soaps, the body whitening lotion and the face whitening cream religiously for the last 6-8 months. I am a mixed race by ancestry, mother being English, father being Indian. My skin tone color is caramel to beige but my arms, face and neck are quite tanned due to sun exposure, so there is a distinct uneveness in skin tone. While using the stalder products I have been using a sun screen when eva out in the sun. I would like to know just exactly how long it takes to work as I have seen no difference? Has anybody else experienced the same issue with this product?

Diana Stalder products did not work for me and I also found it to be really irritating to my skin.

You should avoid sun exposure. Sunblocks only protect you for so little time. Your skin is more sensitive while using whitening products, so it will be easier to burn.
