Key Ingredients

• Biodesigned Signal Peptide: Biomimetic, five amino acid peptide that supports active melanocytes and keratinocytes to help strengthen lashes/eyebrows, enhance color, and increase visible density
• Biodesigned Elastin: Biomimetic, full-length elastin protein that helps supplement elastin where it’s most needed to anchor the follicle—minimizing fall out and maximizing visible density, length/fullness, and volume/shape
• Biodesigned Keratin: Biomimetic, full-length keratin protein that helps supplement keratin where it’s most needed to strengthen the follicles
• Biodesigned Hepatocyte Growth Factor: Biomimetic, full-length signal protein that collaborates with natural growth factors to support anagen (growth) and catagen (transition) phases to promote visibly thicker, longer lashes/fuller brows
• Biodesigned Isopropyl Cloprostenate: Biomimetic, analog of prostaglandin included at a specific concentration to safely and effectively support natural lash/brow growth for visibly enhanced eyelashes/eyebrows

Clinical Study Results

• +40% improvement in brow volume/density
• +22% improvement in lash volume/density
• +22% longer-looking lashes

*Based on the results of two 12-week independent clinical studies of the 2026 NULASTIN® LASH and BROW formulas among 31 participants per formula (21 evaluable for lash image analysis). Lash thickness improvement was not statistically significant at the group level; this figure reflects an individual best-case result. Other individual “up to” results reflect top-performing subjects across each study. Results may vary

How to Use

• Apply both serums twice daily (AM and PM) after skincare and before makeup application
• Always start with clean, dry eyelids and eyebrows
• LASH: Use the applicator to apply a thin line of serum to the base of the upper lash line, from inner to outer corner. Do not apply to the lower lash line
• BROW: Use the applicator to apply the serum onto the eyebrows in short, upward brush strokes
• Warning: Use only as instructed. For external use only. Do not get in eyes; in the event of direct contact, rinse with cool water. To reduce the risk of irritation or other side effects, do not apply to lower lash line. If redness or irritation occurs, stop using the product. If irritation or redness persists, consult your doctor. If you tend to have sensitivity to products, we recommend a patch test before use. Do not use if you are pregnant or nursing. If you are being treated for any eye or serious medical condition, consult your doctor prior to use. Keep out of reach of children
