twenty/twenty beauty Lash & Brow Serum — 3‑Ingredient Vegan Formula, Ophthalmologist‑Developed for Sensitive Eyes

Get Growing Lash & Brow Serum is a simple, three-ingredient, ophthalmologist-developed oil formula designed to help lashes and brows appear thicker and healthier with nightly use.

This serum combines castor, coconut, and argan oils in a clean, vegan formula created by a board-certified eye doctor to support lash and brow appearance while remaining safe for sensitive eyes and contact lens wearers. The product focuses on nourishing existing hairs, supporting the look of new follicle formation, and protecting delicate skin around the eyes without prostaglandins, parabens, or animal testing. Packaging uses a pump to prevent double-dipping and keep application sanitary.

How quickly will I notice fuller lashes and brows?

Individual results vary, but most users report visible improvement with consistent nightly application between 4 and 12 weeks. Early benefits typically include improved hair sheen and reduced breakage, while thicker-looking growth may take longer depending on your natural cycle.

• Apply nightly for best results; many see changes by 4–12 weeks.
• Consistent, gentle application maximizes nourishment and reduces breakage.
• Castor oil’s long history of use on eyelashes supports gradual improvement.

What exactly is in this serum and is it safe for sensitive eyes?

The formula contains only three plant-derived oils: castor, coconut, and argan. It’s vegan, cruelty-free, prostaglandin-free, and paraben-free, and the ingredients were selected to minimize irritation for sensitive skin and eyes.

• Castor oil: hydrates and supports stronger-looking hair strands.
• Coconut oil: conditions and reduces protein loss in hair fibers.
• Argan oil: adds antioxidants and shine while softening hairs.

How do I apply the serum for safe, effective use?

Use one small pump on clean, dry lashes and gently apply to the upper and lower lash lines at the root with a finger, brush, or Q-tip. Add another small pump to smooth across eyebrows; leave the oils on overnight and rinse in the morning as usual.

• Pump once for lashes, once more for brows to avoid waste.
• Use a clean applicator each time to keep the product sanitary.
• Safe if it contacts the eye — the formula is used similarly to long-standing castor oil eye treatments.

Will this interfere with my contacts or eye makeup routine?

The serum is formulated to be contact-lens friendly and safe for sensitive eyes when used as directed. Apply at night after removing contacts and eye makeup to allow the oils to absorb while you sleep; continue your normal daytime routine after rinsing if desired.

• Designed to be safe for contact lens wearers when used overnight.
• Apply after removing makeup and contacts to reduce transfer or irritation.
• Pump packaging reduces contamination risk compared to double-dip wands.
