The innovative hydrogel formula transitions to transparency as active ingredients penetrate the skin barrier through thermal activation. Formulated with Vitamins B3 and B8, this dermatologically-tested mask effectively addresses dullness while delivering intense hydration for a luminous, glass-like complexion. Each pack contains 5 professional-grade treatments.
