Rodan + Fields Lash Boost Serum — 5 ml Peptide Lash & Brow Conditioner

Rodan + Fields Lash Boost is a peptide-based conditioning serum designed to support fuller, longer-looking eyelashes and eyebrows through nightly application. The formula uses hydrating and conditioning ingredients (including almond extract) to strengthen lashes and help prevent breakage, positioning itself as a gentler alternative to prescription prostaglandin analogs. Applied along the lash line and to clean brows, it aims to enhance definition and durability over consistent daily use. At $155 for 5 ml, the cost per month is premium (approximately $1.55 per application), and it sits in the boutique-price category. Rodan + Fields has established credibility in direct-sales beauty, though this product lacks the viral momentum or independent community consensus of market leaders like GrandeLASH-MD or The Ordinary Multi-Peptide Serum. Most suitable for consumers seeking a brand-name, conditioning-focused lash serum who prioritize the Rodan + Fields reputation and gentle formulation over rapid visible growth.
