A direct vitamin C powder with a customizable concentration. This refined powder visibly reduces signs of aging by brightening and balancing uneven skin tone and protecting your skin from the effects of damage caused by environmental stressors. But because it’s made of 100% vitamin C, it’s designed to be mixed with other serums, creams, or moisturizers in your skincare routine—allowing you to create a custom vitamin C treatment. Mix a small amount with other products in the palm of your hand and apply to the face once daily, ideally in the evening. Avoid the eye contour and contact with eyes. Use sun protection during the day. A tingling sensation can be expected; if the sensation is too strong, reduce the amount of ascorbic acid (Vitamin C) to reduce the strength. If irritation occurs, rinse off, cease use, and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our website for a patch test guide, regimen guide, and product compatibility. Keep out of reach of children. Regimen Step: Mix with other products.
