Most experts agree: when it comes to skincare, the purer the better.

Advocates of organic products in particular argue that, since they contain a higher concentration of natural actives, and hence a closer affinity to the skin's own make-up, they are better able to support the skin's natural processes of cell renewal, hydration, oxygenation and protection.

Pure, natural and organic formulas are an especially important choice for those with sensitive skin conditions, such as acne or eczema, as they are less likely to irritate or cause reactions.
