A common complaint from users of skin whitening products is that there can be a so-called “rebound effect” that actually causes the skin to darken after some period of time. Some brands of whitening products are notoriously bad in this respect, so we are often asked what can be done to prevent rebound.
As it turns out, the best thing you can do to avoid the rebound effect is to use the right products! Rebound effect is very much dependent on the specific formulation of a given product. For example, hydroquinone and mercury—in addition to having serious health concerns—are known for the rebound effect. And when arbutin (a.k.a. bearberry extract) is formulated together with certain other ingredients, it can indeed have a significant rebound effect. Apparently this is a serious problem with some skin care brands.
But in genuine Diana Stalder products, the formulations are specifically engineered to inhibit the rebound effect. The product development team at Stalder Laboratories carefully tests and refines each product for maximum safety and effectiveness, and preventing rebound effect is only one part of this dedication to top quality.
