L-ascorbic skin treatment formulations are provided in a storage container in the form of a vial construction having separate first and second compartments. Solid L-ascorbic acid is located in the first compartment and a liquid vehicle composition is located in the second compartment. The vial is constructed to allow for the combining of the L-ascorbic acid and the liquid vehicle composition by a user immediately prior to a topical application of the combined formulation to the skin. The first compartment may be in the form of a plug for the vial. A cover may be provided which, when screwed down, punctures a wall of the first compartment to allow the mixing of the contents of the two compartments.
