Sesderma Hidraderm TRX Roll-On Focal is a spot-on treatment for dark spots that is suitable for all skin types, including the most sensitive. This practical roll-on is the perfect solution if you have just one small area that is hyperpigmented and don\'t want to buy a whole range of products just for that one dark spot, but also to use as a complement for the most stubborn dark spots that you have and that you wish to fade away by using a treatment a few times a day.
