💡 A professional overnight retinoid cream from CIRCADIA built for mature, dull, or environmentally stressed skin — where a single leave-on step delivers multi-mechanism renewal while the client sleeps.

The core is encapsulated Retinyl Acetate, released gradually through the night via a cyclodextrin delivery system for visible cell turnover with reduced surface irritation. Niacinamide works alongside it to buffer sensitivity and support tone evenness — a pairing that makes the retinoid experience more tolerable for clients new to vitamin A. The SK-Influx ceramide-lipid complex mirrors the skin's own barrier matrix to lock in overnight moisture, while the Synchrolife® peptide-botanical blend targets the visible signs of fatigue, puffiness, and blue-light exposure. The result: clients wake to skin that reads as more rested, firmer, and refined.

For estheticians running anti-aging or corrective facial programs, this fits cleanly as a retail home-care anchor — pairing naturally with a morning SPF recommendation and supporting continued results between appointments.

Add it to your corrective skincare protocols when clients are ready to commit to a nightly vitamin A routine.

• Visible Cell Turnover Support: Retinyl Acetate — encapsulated for stability and gradual release — converts to active vitamin A in the skin over the overnight wear window, helping accelerate the appearance of skin renewal. With consistent use, skin appears smoother, more refined in texture, and visibly younger-looking.
• Barrier Restoration and Moisture Retention: The SK-Influx ceramide-lipid complex (Ceramide NP, AP, EOP, Phytosphingosine, and Cholesterol) mirrors the skin's own lipid matrix, helping reinforce the protective barrier. A stronger visible barrier supports overnight moisture retention, leaving skin looking plumper and feeling more comfortable by morning.
• Improved Skin Tone Evenness and Pore Appearance: Niacinamide at a functional concentration works alongside the retinoid active to help visibly even skin tone and reduce the appearance of enlarged pores, supporting a more uniform, refined complexion over time.
• Firmer, More Resilient-Looking Skin: The TECA triterpenoid complex (Asiaticoside, Madecassic Acid, and Asiatic Acid) — the purified active fraction of Centella Asiatica — supports the visible appearance of firmer, more resilient skin texture, contributing to a more toned and rested complexion.
• Visible Fatigue and Puffiness Reduction: The Synchrolife® complex (Rosemary Leaf Extract, Palmitoyl Tetrapeptide-7, and Chrysin) addresses the visible signs of fatigue and blue-light exposure — including the appearance of puffiness, dark circles, and fine lines — helping skin look more rested and refreshed in the morning.
• Antioxidant Defense and Brightening: Tetrahexyldecyl Ascorbate, a lipid-soluble vitamin C ester, provides antioxidant protection and supports a visibly brighter, more even-toned skin surface throughout the overnight wear period.

Retinyl Acetate - known as Vitamin A (Retinyl Acetate): A vitamin A ester that is converted step-by-step into active vitamin A (retinol, then retinoic acid) within the skin over the overnight absorption window. This conversion process supports visible cell turnover, helping skin appear smoother, more even in texture, and more refined over time. Hydroxypropyl Cyclodextrin in the formula encapsulates the Retinyl Acetate molecule, improving its stability and promoting controlled, gradual release into the skin during wear.

Ceramide NP / Ceramide AP / Ceramide EOP / Phytosphingosine / Cholesterol — Ceramide-Lipid Barrier Complex (SK-Influx): A five-component lipid complex that mirrors the composition of the skin's own protective barrier, combining three ceramide subtypes (NP, AP, EOP), phytosphingosine, and cholesterol. Together, these lipids intercalate into the outermost layers of the skin, helping to reinforce the barrier, reduce transepidermal water loss, and support a visibly plumper, more hydrated complexion. This complex is identified by the brand as SK-Influx.

Niacinamide - known as Niacinamide (Vitamin B3): A well-researched form of vitamin B3 that, at functional concentrations, helps visibly even skin tone, reduce the appearance of pores, and support the skin's surface barrier. In the context of this retinoid-containing formula, niacinamide also helps offset potential visible redness or sensitivity at the skin surface that may accompany vitamin A use, making the overall overnight experience more comfortable and the visible results more balanced.

Asiaticoside / Madecassic Acid / Asiatic Acid — Centella Asiatica Triterpenoid Complex (TECA): Three purified triterpenoid actives derived from Centella Asiatica — Asiaticoside, Madecassic Acid, and Asiatic Acid — working together as the standardized TECA complex. This combination is associated with supporting the visible appearance of firmer, more resilient skin texture and a more even, rested-looking complexion. The brand identifies this complex as TECA (Titrated Extract of Centella Asiatica), a standardized professional-grade ingredient.

Rosmarinus Officinalis Leaf Extract / Palmitoyl Tetrapeptide-7 / Chrysin — Synchrolife® Complex: A three-component patented complex combining Rosemary Leaf Extract, a skin-conditioning peptide (Palmitoyl Tetrapeptide-7), and Chrysin (a naturally derived flavonoid). Together, these actives are positioned to address the visible appearance of fatigue, puffiness, and fine lines associated with exposure to blue light (digital screens) and disrupted sleep. Rosemary provides antioxidant defense, Palmitoyl Tetrapeptide-7 supports visible skin firmness, and Chrysin helps address the appearance of dark circles and puffiness.

Tetrahexyldecyl Ascorbate - known as Tetrahexyldecyl Ascorbate (Lipophilic Vitamin C): A lipid-soluble, highly stable ester form of vitamin C that is capable of penetrating the lipid-rich skin barrier more readily than water-soluble vitamin C forms. In this leave-on overnight cream, it delivers antioxidant defense and helps support a brighter, more even-toned appearance of the skin surface. Its oil-soluble nature makes it particularly well-suited to integration in a rich cream emulsion.

1. Complete the client's evening cleansing routine and apply any prescribed serum before proceeding to this cream.
2. Dispense 1–2 pumps of the cream onto clean fingertips.
3. Apply evenly over the face and neck using gentle upward strokes, avoiding the eye area.
4. Allow the cream to absorb fully; the client wears it overnight as the final step in their evening routine.
5. Advise the client that this product is for nighttime use only and to apply a broad-spectrum SPF moisturizer each morning, as vitamin A actives increase photosensitivity.

Retinol protocol integration for professional home-care programs

When recommending this cream as post-treatment home care — for example, following a chemical peel, microneedling, or resurfacing facial — confirm the skin has fully re-epithelialized before introducing it into the client's routine, as the retinoid component is not suitable for use on actively sensitized or compromised skin. For clients new to vitamin A, instruct them to begin with 2–3 applications per week, increasing frequency gradually as tolerance builds, to minimize visible adjustment responses (flaking, temporary sensitivity). At the retail moment, emphasize the pairing with a morning SPF: clients using vitamin A at night must not skip daytime UV protection — this is both a safety and efficacy point that drives consistent SPF retail conversion.
