FACTORFIVE Lash/Brow Growth Serum

FACTORFIVE Lash & Brow Growth Serum is a growth factor serum designed for thinning, sparse, or over-tweezed lashes and brows. Powered by human stem cell conditioned media alongside copper peptides, biotin, niacinamide, and sodium hyaluronate, it supports the appearance of fuller, denser lash and brow growth with consistent daily use. This lightweight formula is suitable for all skin types and precise enough to apply along the lash line without irritation.

Key Benefits

Growth Factor Technology - Human stem cell conditioned media delivers a concentrated blend of signaling proteins and peptides that encourage follicles to support fuller, healthier-looking lash and brow growth.

Peptide-Driven Follicle Support - Bis(Tripeptide-1) Copper Acetate and Myristoyl Pentapeptide strengthen the follicle environment and help reduce lash and brow shedding over time.

Deep Hydration and Conditioning - Sodium hyaluronate and panthenol condition each strand while keeping the delicate lash and brow area moisturized and resilient.

Brightens the Eye Area - Niacinamide and sodium ascorbyl phosphate gently even the skin tone along the brow and lash line, supporting a more awake and refreshed appearance.

Antioxidant Defense - Tocopherol and troxerutin protect follicles from oxidative stress that can accelerate lash and brow thinning over time.

Caffeine-Activated Stimulation - Caffeine stimulates circulation in the follicle area, promoting a more active growth environment for both lashes and brows.

This serum is ideal for anyone experiencing thinning lashes or sparse brows, whether from genetics, age, hormonal shifts, or years of waxing and threading. It suits all skin types, including dry, oily, combination, sensitive, and mature, so nearly anyone can incorporate it without concern about reactivity.

If you have over-tweezed your brows or want to rebuild fullness in areas that have grown patchy over time, FACTORFIVE Lash & Brow Growth Serum is one of the most targeted options available outside a clinical setting. The lightweight, water-based formula applies cleanly and precisely without migrating into the eyes.

It also works well for those navigating lash changes from extensions, medication-related thinning, or postpartum hair shifts. Because it is formulated specifically for the sensitive eye area, it can be used on bare, extension-free lashes as part of a dedicated rebuilding routine.

Apply to clean, completely dry skin twice daily, both morning and night. Consistency is everything with growth factor formulas, and skipping even a few days can slow visible progress. Most clients see the biggest transformation in brow density, so do not neglect the brows in favor of the lashes.

Prepare: Shake gently before each use. Start with clean, dry lashes and brows. Remove all makeup and allow the skin to dry completely before applying.

Apply: Using the precision brush applicator, draw a few short strokes along the upper lash line, starting from the inner corner and working outward. Apply directly onto each brow, focusing on sparse areas and the outer thirds.

Technique: Use a light feathering motion rather than heavy strokes. Avoid tugging on the lash line, and do not apply to the waterline or lower lash line unless directed by your esthetician.

Frequency: Apply morning and night for best results. Most users see noticeable changes within 6 to 8 weeks of twice-daily use. Follow with a broad-spectrum SPF in the morning to protect the surrounding skin.
