The Vitamin C Suspension 23% + HA Spheres combines direct vitamin C and hyaluronic acid to visibly reduce signs of aging while brightening and balancing uneven skin tone. This water-free formula provides 23% pure L-ascorbic acid, stable in its form. It is supported by hyaluronic acid spheres for optimal hydration. The grainy texture is due to the suspended vitamin C powder in an oil-like base, which requires a few seconds to absorb. This product can be diluted in a cream base to facilitate absorption and build tolerance over time.
