Morning routine
Apply a rice-grain amount under each eye with the ring finger. Tap until absorbed. Follow with sunscreen.


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.
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
Caffeine supports a fresher, less puffy morning eye area.
Hyaluronic Acid plumps thin under-eye skin without weight.
Peptides support firmness around the orbital bone.
How the actives work together
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
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.

In a single-blind clinical trial, a topical caffeine and vitamin K treatment significantly reduced the look of dark circles, a 16% improvement from baseline. Every participant saw visibly brighter, smoother under-eye skin by week four.
Results from published peer-reviewed studies on individual active ingredients. Individual product results may vary.
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.
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.
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.
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.
Aloe Barbadensis Leaf Juice
Botanical humectant used as a comforting base across serums, baby care, and cleansers. High concentrations deliver noticeable cooling and hydration.
Hydrolyzed Rice Protein
Its small protein fragments form a light conditioning film along the strand, smoothing the surface and supporting a stronger look.
The serum's focused benefit reaches its peak with consistent daily use.
Individual results vary based on skin condition and routine consistency.
