💡 A periorbital serum built around a vascular dark circle complex — four coordinated actives (Dipeptide-2, Hesperidin Methyl Chalcone, N-Hydroxysuccinimide, and Chrysin) that target the blood-derived pigmentation responsible for blue-toned under-eye discoloration, where most single-ingredient brighteners fall short.

The peptide load goes further: Acetyl Tetrapeptide-5 (Eyeseryl) addresses the visible appearance of puffiness and eyelid swelling, while the Matrixyl 3000 pairing (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7) works on surface texture and fine lines with extended leave-on contact. Five molecular-weight forms of hyaluronic acid stack hydration across the periorbital surface, and Poria Cocos mushroom extract delivers beta-glucan and triterpene bioactives to visibly calm redness and irritation. The fragrance-free, all-skin-type formula integrates cleanly into eye treatment services and pairs directly with the brand's Sun & Moon Eye Synergy Cream as a retail take-home system.

A strong fit for estheticians whose clients present with vascular dark circles, puffiness, or dehydration-driven fine lines around the eye contour.

• Visibly reduces dark circles: The dark-circle complex — Hesperidin Methyl Chalcone, N-Hydroxysuccinimide, and Chrysin — targets the vascular and pigment-related causes of under-eye discoloration, helping brighten and even the appearance of the periorbital area over time.
• Reduces the appearance of under-eye puffiness and bags: Dipeptide-2 and Acetyl Tetrapeptide-5 work together to visibly reduce the look of fluid accumulation and swelling around the eye area, supporting a smoother, more rested appearance.
• Smooths and firms the appearance of the eye area: Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 condition the periorbital skin to visibly improve the appearance of fine lines and help the skin look firmer and more toned.
• Soothes and calms the appearance of redness and irritation: Palmitoyl Tetrapeptide-7 and Poria Cocos Sclerotium Extract help reduce visible signs of redness and irritation in the sensitive eye area, supporting a calmer, more uniform skin tone.
• Deep, multi-level hydration: A stack of four hyaluronic acid forms — each with a different molecular weight — delivers surface and subsurface moisture retention, keeping the delicate eye-area skin visibly plump, smooth, and hydrated throughout the day.
• Compatible with all skin types: Fragrance-free formulation with a mild, well-tolerated ingredient profile makes this serum appropriate for sensitive, dry, oily, combination, and breakout-prone skin around the eye area.

Dipeptide-2, Hesperidin Methyl Chalcone, N-Hydroxysuccinimide & Chrysin - the Vascular Dark Circle Complex: A group of four coordinated actives designed to address the appearance of dark circles with a vascular origin. Dipeptide-2 is a Val-Trp dipeptide associated with supporting lymphatic drainage, helping reduce the look of fluid accumulation and discoloration beneath the eye. Hesperidin Methyl Chalcone (a bioflavonoid derivative), N-Hydroxysuccinimide, and Chrysin work together to address the visible pigmentation from hemoglobin breakdown products — the blue-brown discoloration that develops when blood pools under the thin periorbital skin. Together, these actives target the cosmetic appearance of dark circles from multiple angles.

Acetyl Tetrapeptide-5 & Palmitoyl Tetrapeptide-7 - Eye-Area Peptide Actives: Two palmitoyl- and acetyl-modified peptides with complementary roles in the periorbital area. Acetyl Tetrapeptide-5 (also known in industry as Eyeseryl) is specifically associated with reducing the visible appearance of under-eye puffiness and eyelid edema by supporting drainage and vascular permeability at the skin surface. Palmitoyl Tetrapeptide-7 (a component of the Matrixyl 3000 complex) is a skin-conditioning peptide that helps improve the visible appearance of skin texture, firmness, and tone with extended leave-on contact.

Palmitoyl Tripeptide-1 - known as Matrixyl (component): A lipophilic tripeptide delivered via a palmitoyl chain for enhanced skin surface affinity. As a leave-on active with extended contact time, Palmitoyl Tripeptide-1 is a well-recognized skin-conditioning peptide associated with improving the visible appearance of fine lines and skin smoothness in the periorbital area. It works in concert with Palmitoyl Tetrapeptide-7 — together forming the Matrixyl 3000 pairing — providing a dual-peptide approach to visible surface texture improvement.

Poria Cocos Sclerotium Extract - known as Poria Mushroom Extract: A bioactive fungal extract derived from the sclerotium (the dense, nutrient-storing body) of Poria cocos mushroom. Delivers both polysaccharides (specifically beta-glucans) and triterpene compounds, the two active fractions cited in the product's key technology description. Beta-glucan polysaccharides function as skin-surface conditioning agents with hygroscopic properties, while the triterpene fraction contributes to the visible soothing and calming appearance associated with this extract in cosmetic literature. Consistent with the brand's 'mushroom' positioning.

Multi-Weight Hyaluronic Acid Complex: Five distinct forms of hyaluronic acid — Sodium Acetylated Hyaluronate, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, and Sodium Hyaluronate — provide layered hydration across different depths of the stratum corneum. The crosspolymer form creates a long-lasting moisture reservoir on the skin surface; standard sodium hyaluronate provides immediate surface humectancy; hydrolyzed (lower-molecular-weight) forms penetrate into upper epidermal layers; and the acetylated form offers enhanced lipophilicity for improved skin affinity. The combined system supports a sustained improvement in the appearance of skin hydration, plumpness, and fine line visibility in the delicate eye area.

1. Cleanse the client's face thoroughly and pat the skin dry before beginning the eye treatment.
2. Shake the bottle gently before each use to ensure even distribution of the formula.
3. Dispense a small amount of serum — typically a pea-sized drop per eye — onto a clean fingertip or a cosmetic spatula.
4. Apply the serum to the periorbital area, beginning at the inner corner of the under-eye and working outward along the orbital bone, then continuing along the upper lid if appropriate.
5. Use light tapping motions with the ring finger to press the serum into the skin — avoid pulling or rubbing the delicate periorbital tissue.
6. Allow the serum to absorb fully before applying any subsequent eye products.
7. For enhanced results, follow with the Sun & Moon Eye Synergy Cream layered on top of the serum after absorption.

Layering and service integration

This serum is explicitly designed to be used under the brand's Sun & Moon Eye Synergy Cream — the serum delivers the active peptide, brightening, and hydration load, while the cream provides occlusion and seals in the treatment. When performing an eye treatment service, apply the serum as the active treatment step and the cream as the finishing/sealing step. This two-step pairing is also a natural retail conversation: after demonstrating the layered protocol on the client, recommend both products as a home-care system for between-appointment maintenance. Clients with pronounced dark circles of vascular origin (blue-toned, visible through thin skin) are the strongest candidates for visible results from this formula — set appropriate expectations for clients whose dark circles are primarily structural (hollow tear trough) or hyperpigmentary in origin, as results for those presentations will be more limited.
