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.

A Peptide Solution and Biotin condition and fortify every hair while Panthenol nourishes the follicle line, all on a comforting Aloe Vera base. Brows look denser, lashes look fuller and healthier — the confident, defined frame your eyes deserve, with visible improvement in as little as a few weeks.

How this formula works

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.

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.

    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.

    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.
