RODAN + FIELDS Lash Boost Serum 5 ml — Nightly Eyelash & Brow Enhancer for Fuller, Longer-Looking Lashes

RODAN + FIELDS Lash Boost Serum is a nightly eyelash and brow serum formulated to help lashes and brows appear fuller, longer-looking, and conditioned with a simple once-a-day application.

This 5 ml bottle of Lash Boost is designed for nightly use along the lash line and on clean brows to promote a visibly more defined eye area. The lightweight, quick-absorbing formula includes hydrating and conditioning ingredients that aim to protect lashes from breakage while being gentle on the skin and eye area. It comes in a travel-friendly size perfect for testing the product or keeping in your bedside routine.

How do I use Lash Boost each night?

Apply the serum once nightly on clean, makeup-free eyelids and brows. Use the thin applicator to draw a single line along the base of the upper lashes and apply lightly to sparsely populated brow areas; allow it to dry before other products.

• Apply to clean skin only, after removing eye makeup.
• Use a single thin stroke along upper lash base; do not get product in the eye.
• Apply to brows where you want more definition; let dry fully.
• Consistency matters—apply nightly for best observational results.

What benefits can I expect and when might I notice them?

The serum supports the appearance of fuller and longer-looking lashes and brows by conditioning and hydrating the hair and the surrounding skin. Individual results vary, but many users observe changes within several weeks when used regularly as directed.

• Targets lash and brow definition for a more framed eye look.
• Hydrating ingredients help reduce breakage and dryness.
• Conditions hairs to appear healthier and more resilient.
• Non-irritating formula suitable for daily evening use.

Is the formula safe for sensitive eyes and what should I watch for?

The Lash Boost serum is formulated to be gentle around the eye area, but it contains almond extract, so avoid if you have a nut allergy. Discontinue use and consult a healthcare professional if you experience persistent irritation, redness, or an adverse reaction.

• Gentle, skin-friendly formula intended for daily use.
• Contains almond extract; not suitable for those with nut allergies.
• Do not apply to the inner eyelid or get product directly in the eye.
• Stop use if irritation or unusual symptoms occur.

How does Lash Boost fit into my beauty routine?

Integrate this serum as a simple step at night after cleansing and before any night creams—no special tools needed. Because it absorbs quickly, it won’t interfere with other skincare products if applied as directed and allowed to dry.

• Use after removing makeup and cleansing the eye area.
• Apply before heavier creams or overnight treatments once dry.
• Travel-friendly 5 ml size fits easily in toiletry bags.
• Quick application—part of a streamlined nighttime regimen.

Who is this for: RODAN + FIELDS Lash Boost Serum is for anyone seeking a gentle nightly serum to enhance the look of eyelashes and brows—ideal for those wanting more definition, protection against breakage, and a low-effort addition to an evening skincare routine. It is not recommended for people with almond (nut) allergies or anyone advised by a healthcare provider to avoid such topical eye-area products.
