Nighttime Repair Retinol Cream | Circadia

Circadia was founded on the science of circadian rhythms, the understanding that the skin operates on a biological clock that governs when it repairs, renews, and defends itself. The peak repair window happens at night, when the skin's natural cell turnover rate is highest, blood flow to the skin increases, and the absence of UV exposure means that regenerative processes can run without interruption. Nighttime Repair Retinol Cream was formulated specifically to capitalize on that window, delivering actives that align with and amplify what the skin is already trying to do while you sleep.
Retinyl Acetate, the formula's Vitamin A source, is an ester form of retinol that converts to retinoic acid progressively within the skin. This conversion pathway makes it significantly more tolerable than pure retinol while still delivering the same core benefits: accelerated cell turnover, free radical scavenging, UV damage repair, and support for keratinocyte differentiation and proliferation. It is appropriate for those new to Vitamin A as well as those who want a reliable nightly maintenance dose without the intensity of higher-percentage formulas.
SK-Influx, a ceramide complex containing Ceramide NP, Ceramide AP, Ceramide EOP, Cholesterol, and Phytosphingosine, addresses the barrier dimension of aging skin directly. As the skin ages, its ceramide content declines, weakening the barrier and allowing transepidermal water loss to accelerate. SK-Influx replenishes these critical lipids, restoring the barrier's structural integrity and locking in the hydration that supports effective overnight repair.
Synchrolife is Circadia's proprietary chronobiology active, formulated to rebalance the skin's circadian clock when it has been disrupted by stress, poor sleep, blue light exposure, or environmental factors. Skin that is out of sync with its circadian rhythm shows it visibly through fatigue, dullness, and reduced resilience. Synchrolife helps restore that rhythm, making the skin more responsive to the repair signals that drive genuine overnight renewal.
Timecode targets the chronic low-grade inflammation that silently accelerates visible aging by degrading collagen, reducing elasticity, and deepening fine lines over time. By calming that inflammatory baseline, Timecode allows the skin to redirect resources toward regeneration rather than constant inflammatory response.
Palmitoyl Tripeptide-38 and Palmitoyl Tetrapeptide-7 bring collagen-stimulating and anti-inflammatory peptide activity. Niacinamide supports barrier function and reduces redness. Tetrahexyldecyl Ascorbate, a stable oil-soluble Vitamin C, provides antioxidant support and brightening. Ergothioneine, one of the most potent naturally occurring antioxidants, protects against oxidative stress at the cellular level. Centella Asiatica (Asiaticoside, Madecassic Acid, Asiatic Acid) contributes wound-healing, collagen-supporting, and calming botanical action. Chrysin, a natural bioflavonoid, provides additional antioxidant and anti-inflammatory support. Rosemary Leaf Extract and Tocopherol complete the antioxidant complex.

For maximum results, pair Nighttime Repair with a vitamin C serum applied before it in the evening routine. Vitamin C and Vitamin A work synergistically: C handles daytime antioxidant defense and brightening, A handles nighttime cell turnover and repair. Applied together in the PM, after serum then cream, they address aging from two complementary pathways simultaneously rather than competing or canceling each other out. Both are stable in this formula's delivery system, making the combination genuinely effective rather than just theoretically sound.

• In the evening after cleanser and serum, dispense a pea-sized amount onto fingertips and apply all over face and neck.
• Avoid contact with eyes.

Key Ingredients
Vitamin A Ester (Retinyl Acetate): A stable, gentle form of Vitamin A that converts progressively to retinoic acid within the skin, supporting cell turnover, UV damage repair, free radical scavenging, and keratinocyte renewal with a more gradual onset than pure retinol.
SK-Influx Ceramide Complex (Ceramide NP, Ceramide AP, Ceramide EOP, Cholesterol, Phytosphingosine): A multi-ceramide barrier restoration complex that replenishes the lipids depleted by aging and environmental damage, strengthening the skin's structural integrity and locking in moisture overnight.
Synchrolife: Circadia's proprietary chronobiology active that rebalances the skin's circadian clock, restoring the biological rhythm that governs effective overnight repair and renewal when disrupted by stress, poor sleep, or environmental factors.
Timecode: Targets chronic low-grade inflammation that silently accelerates visible aging by degrading collagen and reducing elasticity, calming the inflammatory baseline to allow more resources to be directed toward skin regeneration.
Palmitoyl Tripeptide-38: A collagen-stimulating peptide that supports the skin's structural matrix for firmer, smoother texture with consistent use.
Palmitoyl Tetrapeptide-7: An anti-inflammatory peptide that reduces interleukin-6 production, helping to calm the inflammatory signals that degrade skin quality over time.
Ergothioneine: One of the most potent naturally occurring antioxidants, providing deep cellular protection against oxidative stress that accumulates during the day.
Centella Asiatica Complex (Asiaticoside, Madecassic Acid, Asiatic Acid): A wound-healing and collagen-supporting botanical triad with calming and regenerative properties, particularly beneficial for fragile or sensitized skin.
Niacinamide: Supports barrier ceramide production, reduces redness, and maintains an even, balanced complexion as part of the overnight repair process.
Tetrahexyldecyl Ascorbate: A stable, oil-soluble Vitamin C that provides antioxidant protection and supports brighter, more even skin tone overnight.
Chrysin: A natural bioflavonoid with antioxidant and anti-inflammatory properties that complements the formula's broader regenerative action.
