We strongly recommend sampling any new products prior to purchasing full-size. Samples are painstakingly made to order, and are offered strictly as a means for you to test a product prior to purchasing. They aren't intended as stocking stuffers or travel sizes. You may purchase one sample of each product once.
For example, if you've already purchased a sample of Ghost Nebula Oilserum, you may not order a sample of Ghost Nebula Oilserum again in a future order. We do our best to make sure one sample is generous enough to determine if the product will work for your skin & sensibilities.
You'll find usage instructions on each individual product page under the tab "Application". If you're sampling more than one new product, try each new product separately over the span of 1-2 weeks. If you have a negative reaction, stop using the product immediately. If you have sensitive skin, we recommend starting with an overnight test patch under your jawline, and giving your skin a full 24 hours before judging the result.
