    Need to Know

    Frequently Asked Questions

    How long until I see fuller-looking lashes?
    Many people notice improvement around 8 weeks, with more pronounced results by about 16 weeks of consistent nightly use. Lash growth is gradual, so steady application matters more than any single night.
    How do I apply it correctly?
    On clean, dry skin, apply a thin line of serum along the base of your upper lash line only, avoiding the lower lid and other areas. Let it dry for about 90 seconds before applying anything else.
    Does it contain a prostaglandin like Latisse?
    It uses dehydrolatanoprost, a prostaglandin-analogue ingredient, as part of its Nouri-Plex technology. It is positioned as a cosmetic lash serum, so if you have any eye conditions or concerns, it is best to check with your doctor before use.
    Will results last if I stop using it?
    Like most lash serums, the improved appearance is maintained with ongoing use, and lashes tend to gradually return to their baseline if you stop. Continuing a maintenance routine helps preserve the fuller look.
    Can I use it with lash extensions or on my lower lashes?
    Apply it only to the upper lash line as directed, not the lower lashes. With extensions, check with your lash technician first, since serums and adhesives can interact.

    Loved all of the extra samples.

    Timothy V.

    Received this product from a friend that noticed my lashes were very thin and short. After using the product for approximately a month or so, I started seeing results. They are very noticeable when I curl my lashes. A bit pricey but the product does indeed work and I highly recommend.

    Very effective in just 10 days. Does not discolor the pigment under the eye.

    Diana W.

    I’ve tried 5–7 different eyelash serums, including some very expensive ones, and Obagi is by far the most effective. It noticeably made my lashes longer, fuller, and stronger. I started seeing results within a few weeks, and the improvement kept getting better with consistent use. It’s definitely worth the investment and the best lash serum I’ve ever used. Highly recommend!
