Institut Esthederm Vitamin C² Intense Serum Double Concentrate

This dual-phase brightening serum uses a powerful combination of stabilized vitamin C to target dullness, uneven tone, and early signs of aging with maximum efficiency. The double concentrate format delivers both an immediate radiance boost and long-term antioxidant protection, helping to fade dark spots, revive tired skin, and improve overall luminosity. Its lightweight texture absorbs quickly, enhancing collagen synthesis and strengthening the skin’s natural defenses, leaving the complexion noticeably brighter, smoother, and more energized with consistent use.
