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.

How the actives work together
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

Fine lines and wrinkles visibly softened twofold
In a double-blind, vehicle-controlled facial study, a moisturizer with palmitoyl pentapeptide (Matrixyl) halved the appearance of fine lines and wrinkles versus vehicle by expert grading. Skin looked smoother, more refined.

Fades stubborn dark patches by up to 62%
In an 8-week split-face trial in melasma, 4% niacinamide cut the MASI pigmentation score by 62% — comparable to hydroquinone but with fewer side effects. Good-to-excellent improvement was seen on 44% of the niacinamide-treated sides.

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.
- 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.
- 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.
