Vitamin C Suspension 30% in Silicone is a smooth cream-like formula that uses direct Vitamin C to help visibly reduce signs of aging by brightening and balancing uneven skin tone. This water-free formula provides 30% direct L-Ascorbic Acid which remains completely stable due to the absence of water. What’s more, this water-free formula contains extra-light silicones, which lessen the tingling sensation that can be associated with topical vitamin C treatments.
