medicube Deep Reviving Peptide Eye Serum — 1.01 fl. oz, 20,000 ppm peptides, niacinamide & squalane for fine lines and puffiness

This lightweight Korean eye serum combines a high-density peptide complex with niacinamide and squalane to deliver moisture, support skin texture, and brighten the eye contour. Developed in collaboration with dermatologists and validated through six clinical trials, the formula is gentle enough for sensitive areas while strong enough to be used across the face when extra hydration is needed. Packaged in a 1.01 fl. oz bottle, it works within a simple morning and evening routine: apply, pat, and let absorb.

How does this serum help reduce puffiness and dark circles?

The serum uses a proprietary peptide complex at 20,000 ppm to boost moisture retention and support the appearance of firmer skin around the eyes. Niacinamide works alongside peptides to even skin tone and brighten shadowed areas, while squalane locks in hydration without a heavy residue. Regular use improves the eye area’s overall look by addressing multiple contributing factors simultaneously.

• 20,000 ppm medicube-developed peptide complex targets moisture and texture.
• Niacinamide for brighter, more uniform skin tone.
• Squalane provides lightweight, lasting hydration.
• Clinically tested in six trials for efficacy and mildness.

Will this work for my skin type and can I use it year-round?

The formula is designed for all four seasons and suits a range of skin types, particularly dry or prematurely aging complexions and those noticing dullness or fine lines. Because the texture is hydrating but non-greasy, it layers well under makeup or sunscreen and won’t feel heavy in humid weather. Dermatological testing suggests low irritation potential, making it suitable for sensitive eye areas.

• Suitable for dry, dull, and fine-line-prone skin.
• Lightweight texture that layers under cosmetics and SPF.
• Formulated for year-round use in varying climates.
• Clinically assessed for safety on delicate skin.

How should I apply the eye serum for best results?

Use a small amount morning and night, gently patting the serum into the orbital bone until fully absorbed. For targeted under-eye care, apply sparingly to avoid tugging; it’s also safe to use across the face where extra hydration or peptide support is desired. Consistent application yields the most noticeable improvements in texture and radiance over time.

• Apply a pea-sized amount to each eye area morning and evening.
• Pat gently with ring finger until absorbed; avoid rubbing.
• Can be applied to other dry or fine-line-prone areas of the face.
• Layer under moisturizer and sunscreen for daytime protection.

What ingredients are key and why were they chosen?

The formula centers on an intensive peptide complex developed by medicube to support moisture and texture, backed by niacinamide to brighten and squalane to replenish lipids. These actives are combined to deliver multi-targeted care—hydration, texture support, and tone improvement—without introducing heavy emollients that could weigh down the eye area. Each component was selected for compatibility with sensitive skin and for proven topical benefits in cosmetic use.

• Medicube peptide complex (20,000 ppm) for moisture and resilience.
• Niacinamide to even skin tone and improve brightness.
• Squalane for non-greasy lipid replenishment and barrier support.
• Dermatologist-developed blend tested in six clinical trials.

Who is this for? Medicube Deep Reviving Peptide Eye Serum is aimed at anyone noticing early signs of aging, puffiness, or dark circles who wants a targeted, lightweight treatment. It’s especially useful for people with dry or dull skin seeking improved hydration and texture around the eyes, those who prefer dermatologically-informed formulations, and users who want a product that layers cleanly under makeup and sunscreen. If you want concentrated peptide support in a gentle, everyday serum, this product fits into both minimalist and multi-step skincare routines.
