I have been using this product for almost a month and have definitely seen a lightening in my pigmentation spots and an overall clarity in my skin complexion. The process (de-pigmenting) has also made me more regimental on sunscreen, which I apply after I have applied my D-Pigment Brightening Serum in the morning. I can highly recommend Avene Sunscreen SPF 50 as a choice. I love that all the products have the benefits of the powerful Avene Thermal Springwater from France.
