How To Use

Application:

• Step 1: Cleanse your face thoroughly and ensure skin is completely dry before application
• Step 2: Using the applicator, apply the serum from the root of your eyebrow, following the natural shape of your brow from inner to outer edge
• Step 3: Apply evenly without excess product; blot any overflow outside the eyebrow margin to prevent unwanted hair growth in other areas
• Step 4: Wait 90 seconds for the product to dry completely before continuing your skincare routine

Frequency: Apply once daily, every evening

Timing: Nightly application (PM routine) for optimal absorption and effectiveness

Layering: Can be used with other products including ELASTIderm® Eye Cream and Eye Serum; wait 90 seconds after applying Nu-Cil before applying other eye area products

Expert Tips: For best results, maintain consistent nightly application. Results build progressively, with visible improvements at 8 weeks and more pronounced effects at 12 weeks. Discontinuing use will cause eyebrows to revert to their normal growth cycle. Do not apply to any other facial areas.

FAQ

Q: How quickly will I see results from Obagi Nu-Cil Eyebrow Boosting Serum?

A: Clinical study participants reported visible improvements in eyebrow appearance in as little as 8 weeks, with 100% showing improvement in brow fill and 96% experiencing enhanced density and volume. More pronounced results become evident at 12 weeks with continued nightly use. Individual results may vary depending on your natural eyebrow growth cycle and consistency of application.

Q: How does NouriPlex® Technology work in this serum?

A: NouriPlex® Technology is Obagi's proprietary blend of four key ingredients - biotin, panthenol, sodium hyaluronate, and a unique lipid compound - that work synergistically to target the anagen (growth) phase of the eyebrow hair cycle. This advanced formulation supports keratin production, provides essential hydration, conditions the hair shaft, and helps address the appearance of patchy or thinning brows for fuller, denser, darker-looking results.

Q: Can I use this product if I'm pregnant or nursing?

A: We recommend consulting your physician before using Obagi Nu-Cil Eyebrow Boosting Serum if you are pregnant, nursing, or planning to become pregnant. Whilst the product is designed for external use only, it's always best to seek professional medical advice when introducing new products during pregnancy or whilst breastfeeding.

Q: What happens if I stop using the serum?

A: If you discontinue use of Obagi Nu-Cil Eyebrow Boosting Serum, your eyebrows will gradually revert to their normal growth cycle and appearance. The serum is designed for ongoing nightly use to maintain the improved appearance of fuller, denser, darker-looking brows. Results are not permanent without continued application.

Q: Can I use this serum with other eye area products?

A: Yes, Obagi Nu-Cil Eyebrow Boosting Serum can be used alongside other eye care products, including Obagi ELASTIderm® Eye Cream and Eye Serum. However, you must wait 90 seconds after applying the eyebrow serum for it to dry completely before applying any other products around the eye area. This ensures optimal absorption and effectiveness of all products.

Q: Will the serum darken my natural eyebrow colour?

A: Yes, clinical study participants did experience increased pigment intensity in their natural eyebrow hair colour, resulting in darker-looking brows. This is one of the intended benefits of the serum, contributing to the overall appearance of fuller, more defined eyebrows. The darkening effect enhances your natural colour rather than changing it artificially.

Q: Is this serum suitable if I have sensitive skin or wear contact lenses?

A: The serum is suitable for all skin types, including sensitive skin, and can be used by contact lens wearers. However, if you have a history of eye-related disorders, conjunctivitis, dry eyes, or frequent styes, consult your physician before use. Some individuals may experience mild, temporary irritation when first using the product; if this occurs, reduce application to every other day until your skin adjusts.
