medicube Peptide Eye Serum — Deep Reviving Peptide 1.01 fl.oz, Niacinamide & Squalane for Puffiness and Fine Lines

medicube Deep Reviving Peptide Eye Serum is a concentrated peptide treatment designed to hydrate the eye area and visibly reduce the look of puffiness, dark circles, and fine lines.

This Korean-formulated eye serum combines a high-strength peptide complex with niacinamide and squalane to target common under-eye concerns without heavy texture. Developed in collaboration with dermatologists and validated through clinical testing, the formula aims to deliver lasting moisture and smoother-looking skin. Lightweight enough for daily morning and evening use, it can be applied to the orbital area or across the face for an extra hydrating boost.

How does this serum help reduce puffiness and dark circles?

The product centers on a proprietary peptide complex at 20,000 ppm that helps support the skin’s moisture balance and surface resilience. Niacinamide adds brightening support while squalane locks in moisture, creating a plumper appearance that can make shadows and swelling look less pronounced. Results depend on consistent use and individual skin conditions.

• 20,000 ppm medicube-developed peptide complex to improve moisture retention.
• Niacinamide to help even skin tone and enhance radiance.
• Squalane for lightweight, non-greasy hydration.
• Formulated to be gentle for frequent use morning and night.

Is this suitable for sensitive or dry skin?

The serum has undergone six clinical trials and was formulated to minimize irritation while delivering hydration—making it suitable for dry skin showing early signs of aging. Although the formula is designed for tolerance, patch testing is recommended if you have reactive skin. The composition emphasizes moisture and skin comfort rather than strong exfoliation.

• Clinically tested to assess irritation risk.
• Hydrating squalane supports dry skin without heaviness.
• Peptide complex focuses on moisture and resilience rather than harsh activeifiers.
• Recommended patch test on sensitive or reactive skin types.

How do I use the eye serum for best results?

Dispense a small amount and gently pat it into the orbital bone and eyelid area until absorbed; avoid rubbing or pulling the delicate skin. Use twice daily—morning and night—for consistent improvement in texture and hydration. The serum’s light texture layers well under sunscreen and makeup.

• Apply a pea-sized amount per eye; pat, don’t rub.
• Use after cleansing and before heavier creams or sunscreen.
• Suitable for use across the face when extra hydration is needed.
• Consistent morning and evening application recommended.

What makes medicube’s peptide complex different?

medicube developed the peptide blend in-house through targeted research, resulting in a high-concentration formula intended to deliver moisture and surface support where the skin needs it most. The focus is on improving the appearance of tired-looking eyes by addressing hydration and skin texture rather than relying on a single active. The product is positioned to fit into a routine with other dermatologist-recommended ingredients.

• Proprietary peptide technology developed by medicube.
• High concentration (20,000 ppm) for targeted hydration benefits.
• Formulated to pair well with niacinamide and squalane.
• Designed for routine use with complementary skincare steps.

Who is this for: medicube Deep Reviving Peptide Eye Serum is aimed at people noticing early-to-moderate signs of under-eye aging—such as puffiness, dullness, and fine lines—who want a gentle, hydrating treatment. It suits those who prefer lightweight textures that layer under other products, anyone looking for dermatologist-backed Korean skincare, and users who want a peptide-forward approach without aggressive exfoliation. If you have highly reactive skin or specific medical concerns, consult a dermatologist before use.
