Pigmentation is one of the most common skin concerns my clients have. And I find that the most common mistake in people suffering with pigmentation, is attempting to self-diagnose and then using a little bit of this and a little bit of that from multiple brands.
While this can be ok for some skin concerns, the best way to treat pigmentation is to use prescribed products within the same range. The reason is, these products have been specifically formulated to work together in order to achieve the best possible results.
