Obagi Nu-Cil Eyelash Enhancing Serum is a lash serum that is designed to support the appearance of fuller, denser, and more voluminous lashes with results that continue to build day after day. The serum is powered by innovative NouriPlex™ Technology, a proprietary blend of four key ingredients, which supports the growth phase of lashes. The key ingredients of the serum include:

• Dehydrolatanoprost: This is a prostaglandin analog that is used to treat hypotrichosis of the eyelashes by increasing their growth, including length, thickness, and darkness.

• Biotin: This is a B-vitamin that is essential for healthy hair growth. It helps to strengthen hair and prevent breakage, which can lead to fuller and thicker lashes.

• Panthenol: This is a provitamin of B5 that is used to improve the health and appearance of hair. It helps to moisturize and strengthen lashes, making them less prone to breakage.

• Sodium Hyaluronate: This is a form of hyaluronic acid that is used to hydrate and condition lashes. It helps to improve the overall health and appearance of lashes.

The serum is easy to use. First, cleanse the skin and allow it to completely dry. Then, apply a thin layer of Obagi Nu-Cil Eyelash Enhancing Serum to the base of the upper lash line. Do not apply to the lower lash line.

Positive reviews of the serum indicate that it has made lashes significantly longer, thicker, and more voluminous in as little as eight weeks with continued improvement after that. The serum is also reported to be soothing for lashes and has not caused any negative effects.

Negative reviews of the serum are limited, but some users have reported that it takes longer than eight weeks to see results.
