They are formulated with reactive skin in mind, because our founder has it herself. Every formula is free of parabens, sulfates and PEGs, contains zero alcohol, and is clinically tested for safety, with a microbiology analysis run on each batch. Eye formulas are additionally tested for use in the eye contour, and lip formulas for the fact that they are, inevitably, ingested in small amounts. We use natural fragrances rather than none at all, so if you react to fragrance of any kind, check the full ingredient list — we publish it in full for every product.
