Eight Saints Eyebrow Growth Serum 0.14 fl oz — Biotin & Castor Oil for Thicker, Fuller Brows

Eight Saints Frame Game Eyebrow Growth Serum is a lightweight brow treatment formulated with biotin, amino acids and castor oil to visibly strengthen and support the appearance of fuller, more resilient brows.

This concentrated 0.14 fl oz serum targets sparse or fragile eyebrow hairs with a short ingredient list chosen for performance and tolerability. The formula focuses on nutrient support and moisture balance rather than heavy oils or fragrances, so it layers easily under makeup and won’t feel sticky. Made in the USA, cruelty-free and fragrance-free, this product follows Eight Saints’ philosophy of using a small set of high-impact actives—their "Eight Saints"—to deliver predictable results you can evaluate over daily use.

How does this serum help my brows look fuller without heavy makeup?

The serum works by conditionally strengthening each hair shaft and improving the environment around the follicle so hairs appear thicker and less prone to breakage. Combined humectants and oils help maintain strand flexibility, so existing hairs reach and keep their visible length.

• Biotin and amino acids help reinforce hair structure at the shaft level.
• Hyaluronic acid provides lightweight hydration without greasiness.
• Castor oil adds nutrient-rich emollience to smooth and visually plump strands.
• Non-sticky texture layers under eyebrow makeup and gels easily.

When will I notice a difference if I start using the serum daily?

Visible improvement timing varies by individual, depending on hair cycle and baseline condition; many users report perceivable changes in texture and durability within several weeks. For consistent evaluation, apply daily and observe over a 6–12 week window to allow multiple hair cycles to respond.

• Apply nightly or twice daily to clean brow area for best absorption.
• Expect initial improvements in flexibility and shine within weeks.
• Fuller visual density often becomes noticeable with continued use over months.
• Track progress with photos every 4–6 weeks for the clearest comparison.

Is the formula safe for sensitive skin or those prone to irritation?

Eight Saints designed this eyebrow serum to be fragrance-free and lightweight to reduce irritation risk; the ingredient profile emphasizes gentle actives over aggressive botanicals. Still, patch testing is recommended for anyone with reactive skin or known sensitivities.

• Fragrance-free formula minimizes common irritants.
• Cruelty-free and made in the USA with globally sourced ingredients.
• Small product size (0.14 fl oz) allows low-commitment testing.
• Return policy offers a 30-day window if the product doesn’t meet expectations.

How do I include this serum in my daily grooming routine?

Use the serum as a simple step after cleansing and before heavier creams or makeup. Apply a small amount directly to brows using the applicator, gently brushing through to distribute the serum across the hairs and skin beneath.

• Cleanse the brow area to remove oils and makeup for better absorption.
• Apply a thin layer nightly; morning application is optional under makeup.
• Comb brows with the applicator or a spoolie to shape while product sets.
• Maintain consistent application for several weeks to see results.

Who this is for: This eyebrow serum is suited to people seeking a straightforward, scientifically minded approach to brow care—those with naturally thin, over-plucked, or fragile eyebrows who want a non-greasy, fragrance-free treatment. It’s also a good match for anyone preferring minimalist formulations and cruelty-free manufacturing. If you want a short ingredient list focused on biotin, amino acids, and nourishing oils to improve strand strength and appearance, Eight Saints Frame Game offers a compact, easy-to-use option.
