👁 A dual-formula day-and-night eye treatment from CIRCADIA — built around a clinically recognized peptide and brightening system for clients dealing with dark circles, puffiness, expression lines, and loss of firmness in the periorbital zone.

The Day formula leads with Argireline (Acetyl Hexapeptide-8) to visibly soften crow's feet and expression lines, stabilized Vitamin C (AA2G) for under-eye brightening, and botanical vascular support to reduce the look of morning puffiness. The Night formula shifts to Haloxyl peptides and Retinyl Acetate — targeting hemoglobin pooling and overnight surface renewal in the delicate skin where stronger retinoids are typically avoided. Together, they deliver targeted eye-area support across a full 24-hour cycle.

For practices offering anti-aging or brightening facials, the duo fits naturally as a finish-step service product and a retail conversation anchor — the day/night structure gives clients a clear home-care protocol that reinforces in-treatment results.

Worth adding to the anti-aging facial lineup for clients with persistent dark circles or fine lines around the eyes.

• Visibly Softens Expression Lines and Crow's Feet: Argireline (Acetyl Hexapeptide-8), a neuro-mimic peptide present in the Day formula, helps moderate the repetitive muscle microcontractions that deepen expression lines over time, resulting in a visibly smoother appearance around the eye area with consistent use.
• Reduces the Appearance of Dark Circles: The Haloxyl system targets dark circles through two complementary pathways: Chrysin and N-Hydroxysuccinimide (Day formula) work to break down and clear accumulated blood pigment deposits that cause discoloration, while Hesperidin Methyl Chalcone and Dipeptide-2 (Night formula) support microcirculation and lymphatic drainage to reduce hemoglobin pooling beneath the delicate under-eye skin.
• Brightens and Evens Under-Eye Skin Tone: AA2G (Ascorbyl Glucoside) in the Day formula is a stabilized vitamin C ester that gradually releases active vitamin C upon skin contact, delivering antioxidant protection and contributing to a visibly brighter and more even-toned under-eye appearance with continued use.
• Supports Overnight Visible Renewal: Retinyl Acetate, a vitamin A ester exclusive to the Night formula, converts toward more active retinoid forms at the skin surface during extended overnight contact, helping improve the visible texture and appearance of fine lines in the delicate eye area without the sensitivity risk of stronger retinoid forms.
• Decreases Visible Puffiness and Signs of Fatigue: Ruscus Aculeatus Root Extract (Butcher's Broom) and Aesculus Hippocastanum Extract (Horse Chestnut) in the Day formula provide complementary microvascular support — Butcher's Broom tones and tightens vascular walls while Horse Chestnut's aescin content supports fluid drainage, helping visibly reduce puffiness and the look of under-eye fatigue.
• Firms and Supports Under-Eye Skin Structure: Palmitoyl Oligopeptide and Palmitoyl Tetrapeptide-7 — the peptide components of the Haloxyl system present in both formulas — signal structural support in the fragile under-eye dermis, contributing to a visibly firmer, more lifted appearance over time.

Acetyl Hexapeptide-8 — known as Argireline: A neuro-mimic peptide that works by interfering with the neurotransmitter signals responsible for repetitive facial muscle contractions, helping visibly soften expression lines and crow's feet around the eye area over time.: A neuro-mimic peptide that works by interfering with the neurotransmitter signals responsible for repetitive facial muscle contractions, helping visibly soften expression lines and crow's feet around the eye area over time.

Hesperidin Methyl Chalcone / Dipeptide-2 / N-Hydroxysuccinimide / Chrysin / Palmitoyl Oligopeptide / Palmitoyl Tetrapeptide-7 — Haloxyl Multi-Component Dark Circle System: A coordinated blend targeting the main causes of dark circles — Hesperidin Methyl Chalcone and Dipeptide-2 (night formula) improve microcirculation and drainage to reduce hemoglobin pooling; Chrysin and N-Hydroxysuccinimide (day formula) work together to break down and clear accumulated blood pigment deposits beneath the thin under-eye skin; Palmitoyl Oligopeptide and Palmitoyl Tetrapeptide-7 (present in both formulas) support structural support and firmness of the under-eye dermis.: A coordinated blend targeting the main causes of dark circles — Hesperidin Methyl Chalcone and Dipeptide-2 (night formula) improve microcirculation and drainage to reduce hemoglobin pooling; Chrysin and N-Hydroxysuccinimide (day formula) work together to break down and clear accumulated blood pigment deposits beneath the thin under-eye skin; Palmitoyl Oligopeptide and Palmitoyl Tetrapeptide-7 (present in both formulas) provide structural support and firmness of the under-eye dermis.

Ascorbyl Glucoside — known as AA2G (Stabilized Vitamin C): A stabilized ester form of vitamin C (L-ascorbic acid 2-glucoside) that resists oxidation in formulation; upon skin contact, enzymatic cleavage gradually releases free ascorbic acid at the skin surface, delivering antioxidant protection and contributing to a brighter, more even-toned under-eye appearance.: A stabilized ester form of vitamin C (L-ascorbic acid 2-glucoside) that resists oxidation in formulation; upon skin contact, enzymatic cleavage gradually releases free ascorbic acid at the skin surface, delivering antioxidant protection and contributing to a brighter, more even-toned under-eye appearance.

Ruscus Aculeatus Root Extract — known as Butcher's Broom Extract: A plant-derived extract in the day formula containing steroidal saponins (ruscogenins) known to support vascular tone and microcirculation, complementing the anti-puffiness and dark-circle action of the Haloxyl system.: A plant-derived extract containing steroidal saponins (ruscogenins) known to support vascular tone and microcirculation, helping complement the product's visible puffiness-reduction and dark-circle action around the delicate eye area.

Aesculus Hippocastanum Extract — known as Horse Chestnut Extract: A botanical in the day formula rich in aescin, a triterpene saponin that supports microvascular integrity and fluid drainage, contributing to a visibly less puffy and fatigued under-eye appearance.: A botanical rich in aescin, a triterpene saponin that supports microvascular integrity and helps reduce visible fluid accumulation, contributing to a less puffy and fatigued under-eye appearance when used in the day formula.

1. Ensure the client's face has been cleansed and any treatment serums have been applied before beginning eye cream application.
2. For the Day Eye Cream: dispense a small, pea-sized amount of product onto a fingertip or ring finger.
3. Using gentle, light-pressure tapping motions, apply the Day Eye Cream to the orbital bone of the under-eye area, working from the inner to outer corner. Avoid dragging or pulling the delicate periorbital skin.
4. Allow the Day Eye Cream to absorb fully before applying sunscreen or makeup over the eye area.
5. For the Night Eye Cream: dispense a small, pea-sized amount and apply as the final step in the evening skincare routine.
6. Using the same gentle tapping technique, apply the Night Eye Cream to the under-eye area along the orbital bone. Do not apply too close to the lash line to minimize the risk of product migration into the eye during sleep.
7. Advise the client to use the Day formula each morning and the Night formula each evening for consistent 24-hour active delivery.

Integrating the Duo into a Professional Service

This duo is well-suited as a finishing step in anti-aging or brightening facial treatments — apply the Day Eye Cream as the final product during a daytime facial service, immediately after any eye-area treatment mask or serum. For clients receiving regular resurfacing or corrective services, the Night formula's Retinyl Acetate content makes it a compatible home-care pairing; it is gentle enough for the periorbital area where stronger retinoids are typically contraindicated. The dual-formula structure — day actives (Argireline, AA2G, botanicals) and night actives (Haloxyl peptides, Retinyl Acetate) — provides a natural retail conversation anchor: explain to clients that the two formulas work in rotation so the eye area is receiving targeted support around the clock, increasing perceived product value and supporting home-care compliance.
