My lashes look so full they almost look like I have fake lashes on. And my brows have visibly filled in everywhere that I don't need to fill them in on my own anymore...these products work.

A focused approach to lash and brow renewal, the DUAL System targets a key factor in visible thinning: declining elastin at the root. Powered by proprietary Elastaplex® Technology—a precision combination of patented peptides, biomimetic proteins, growth factors, amino acids and potent antioxidants—these performance driven serums deliver concentrated elastin support and protection to the Elastin Root® System, where lash and brow follicles naturally anchor. The result: visibly thicker, fuller looking lashes and brows with noticeably reduced shedding and fallout. See visible results in as soon as 6 weeks and even greater impact at 12 weeks and beyond.

Apply both serums twice daily 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. This cosmetic contains a small amount of Bimatoprost Isopropyl Ester, an analog of prostaglandin. Avoid getting serum in eyes; in the event of direct contact, rinse with cool water. 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.
