The Ordinary Vitamin C Suspension 23% + HA Spheres 2% is a powerful skincare treatment that combines pure L-Ascorbic Acid with Hyaluronic Acid spheres in a water-free, silicone-free formula. This stable suspension helps brighten skin tone, reduce signs of aging, and provide hydration. This product features a unique water-free formulation that helps maintain the stability of the vitamin C. The slightly granular texture is normal due to the vitamin C powder being suspended in an oil-like base. Users may experience a mild tingling sensation upon application. For best results, apply a small amount to face in the AM or PM after cleansing. The formula can be diluted with a cream if needed while building skin tolerance. Not recommended for use with niacinamide, peptides, direct acids or retinoids in the same regimen.
