Eyebrow & Eyelash Serum
Serenvit Eyebrow & Eyelash Serum is BIOSAR's overnight conditioning serum for thinning brows and short, brittle lashes. Biotin supports the look of fuller hair; Keratin reinforces the strand structure; Panthenol conditions the lash line without irritation. Use it nightly before bed on clean, makeup-free brows and lash lines. The fine-tip applicator suits both brow shape and the upper lash line. Suitable for adults with thinning brows after over-plucking, ageing, or post-medical hair loss. Tolerance-tested under dermatological supervision near the waterline.

How the actives work together
Brush it on at night, wake to brows and lashes that look fuller
A conditioning Peptide Solution works alongside Biotin to nourish the look of each brow and lash from the root outward. Panthenol and an Aloe Vera base keep the delicate skin at the lash line calm and comfortable through nightly use. Together they turn a single drop into one complete grooming step, so sparse edges gradually read as denser and more defined.
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.

96% stayed calm and flare-free through the trial
In a 3-month trial, 96% of young participants using a panthenol-containing emollient stayed flare-free, versus 77% on reference care. Provitamin B5 keeps sensitive, barrier-stressed skin soothed and steady day after day.

Topical aloe visibly boosts skin moisture
In this topical forearm trial, an aloe-extract cream significantly raised stratum-corneum water content versus its vehicle, measured by Corneometer. One to two weeks of daily use hydrated skin without disrupting the barrier.

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
Panthenol
Panthenol (Provitamin B5)
Provitamin B5 that supports the skin's repair and hydration signals. Widely used in sensitive, post-procedure, and daily-care formulas.
- 03
Biotin
Vitamin B7, a building block the hair fiber relies on. Applied in leave-on hair and scalp formulas, it supports stronger, more resilient-looking strands and a healthier, more vital scalp.
- 04
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.
