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

medicube Deep Reviving Peptide Eye Serum is a targeted skincare serum that combines a high-concentration peptide complex with niacinamide and squalane to hydrate the delicate eye area and visibly improve puffiness, dark circles, and fine lines.

Layered into a lightweight, fast-absorbing formula, this Korean-developed eye serum focuses on delivering moisture and peptide support where skin thins and shows early signs of aging. The formula features 20,000ppm of a proprietary peptide complex developed by medicube, along with niacinamide to even tone and squalane to replenish lipid balance. Clinical testing and dermatologist collaboration back the product development, and the texture is suitable for year-round use on the eye area or across the face as needed.

How does this serum reduce puffiness and under-eye darkness?

The serum aims to reduce visible puffiness and dark circles primarily through enhanced hydration and peptide-supported skin resilience. Peptides help reinforce the skin’s supportive structure while niacinamide works on tone irregularities; consistent moisture from squalane plumps the area to soften shadowing.

• 20,000ppm proprietary peptide complex to support skin firmness.
• Niacinamide to brighten and improve uneven tone.
• Squalane for lightweight, non-greasy hydration.
• Fast-absorbing texture to layer under creams or makeup.

What results can I expect and how quickly will I see them?

Individual results vary, but clinical testing has shown measurable benefits in reducing the appearance of fine lines, puffiness, and dullness with regular use. Using the serum morning and night improves skin hydration and texture, which over weeks can translate into smoother-looking eye contours and more even tone.

• Daily application recommended—morning and evening—for best outcomes.
• Noticeable smoothing and hydration within days for many users.
• Improved firmness and tone over several weeks with consistent use.
• Suitable for use across the face where delicate hydration is needed.

How should I add this eye serum to my skincare routine?

Apply a small amount after cleansing and any water-based treatments, before heavier creams and sunscreen. Gently pat the product around the orbital bone until absorbed; avoid pulling or rubbing the delicate skin to keep irritation minimal.

• Use after toner/essence and before moisturizer or eye cream.
• Pat gently with ring finger to avoid stretching skin.
• Can be layered under makeup due to quick absorbency.
• Safe for year-round use on the eye area and suitable for dry or prematurely aging skin.

Is this product backed by testing and dermatologist input?

Yes—medicube developed the peptide complex through internal research and collaborated with dermatologists during formulation. The serum has completed six clinical trials indicating effectiveness and a low likelihood of irritation, designed specifically for sensitive eye skin and early signs of aging.

• Proprietary peptide blend developed by medicube researchers.
• Six clinical trials that assess efficacy and irritation potential.
• Formulation support from dermatology experts.
• Suitable for delicate and dry areas showing fine lines or dullness.

Who is this for: medicube Deep Reviving Peptide Eye Serum is intended for anyone noticing early signs of aging around the eyes—fine lines, puffiness, or uneven tone—who wants a lightweight, research-backed treatment. It suits users with dry or dull skin, people who prefer fast-absorbing textures under makeup, and anyone seeking a peptide-forward eye product developed with dermatological guidance.
