Eye Contour Serum

Serenvit Eye Contour Serum is BIOSAR's targeted serum for the eye area. Caffeine supports a fresher, less puffy look in the morning; Peptides support firmness and contour around the orbital bone; Hyaluronic Acid plumps the thin under-eye skin without weight. Use it morning and night with the ring finger, tapping rather than rubbing. The fluid texture absorbs quickly and pairs cleanly under sunscreen or makeup. Suitable for adults; tolerance-tested under dermatological supervision and safe near the waterline.

Why it works

One drop, one mission — and it delivers. Caffeine floods the eye area to melt away puffiness and shadow while a Peptide Solution and Niacinamide firm and smooth the delicate contour, with Rice Protein and Hyaluronic Acid cushioning and hydrating on an Aloe Vera base. Dark circles fade, the contour looks lifted — eyes look wide-awake and rested, fast.

Proven Benefits

What this product does for your skin

  • Fresher eyes

    Caffeine supports a fresher, less puffy morning eye area.

  • Plumped under-eye

    Hyaluronic Acid plumps thin under-eye skin without weight.

  • Gentle near eyes

    Tolerance-tested for comfortable use near the waterline.

How this formula works

Fatigue lifts from the eye area until you look awake, not just treated

Caffeine gets to work on the look of puffiness and shadow around the eye, while a Peptide Solution and Niacinamide refine the appearance of the fine contour. Because Caffeine can feel demanding on such thin skin, Hyaluronic Acid and the Aloe Vera base cushion it with a wash of hydration and calm. Rice Protein rounds it out, so one drop reads as a full brightening, de-puffing step for the eye.

Ingredient Research

Active ingredients backed by published studies

  • 12 weeks

    Fewer fine lines than the same moisturiser without it

    A double-blind split-face trial in 93 women aged 35 to 55: a moisturiser with palmitoyl pentapeptide, used for 12 weeks, reduced wrinkles and fine lines versus the same moisturiser without it, by image analysis and expert grading.

    Fine lines, spots and sallowness improved vs vehicle

    A double-blind split-face trial by the moisturiser's maker, in 50 women with photoaged facial skin: a niacinamide moisturiser used twice daily for 12 weeks reduced fine lines, spots, red blotchiness and sallowness versus its vehicle.

    Caffeine and vitamin K eye pad: dark circles at 4 weeks

    In 11 women, an eye pad with caffeine, vitamin K and emu oil, worn one hour nightly for 4 weeks, reduced dark circles and wrinkle depth versus a water-only pad. The authors attribute the dark-circle result to vitamin K.

What's inside — and what's not

  • 01

    Peptides

    Palmitoyl Tripeptide-1

    Short chains of amino acids that act as messengers in the skin. In anti-aging formulas they support the signals behind firmness and elasticity, softening the look of fine lines for smoother, more resilient skin.

    View research
  • 02

    Niacinamide

    Vitamin B3. Strengthens the skin barrier, helps calm visible redness, and supports balanced sebum. Multi-benefit active suitable for most skin types including sensitive.

    View research
  • 03

    Caffeine

    Stimulant that supports local microcirculation where it is applied. In body and eye-area formulas it helps de-puff and firm the look of skin, for a smoother, more toned and visibly refreshed appearance.

  • 04

    Hyaluronic Acid

    Sodium Hyaluronate

    Humectant that binds many times its weight in water — one of the most effective hydrators available for topical use. BIOSAR formulates it as 8D Hyaluronic Acid: eight molecular weights working together, from higher weights that hold water and plump the surface to lower weights that carry hydration into the deeper stratum corneum, so one layer hydrates at several depths at once.

  • 05

    Aloe Vera

    Aloe Barbadensis Leaf Juice

    Botanical humectant used as a comforting base across serums, baby care, and cleansers. High concentrations deliver noticeable cooling and hydration.

  • 06

    Rice Protein

    Hydrolyzed Rice Protein

    Its small protein fragments form a light conditioning film along the strand, smoothing the surface and supporting a stronger look.
