Can I use MD Brow on over-plucked or sparse brows?

Yes. MD Brow is designed for sparse-looking or over-tweezed eyebrows. It is a cosmetic conditioner for the brow hairs you have and does not create new hairs, but consistent application conditions existing brow hairs and supports the appearance of fuller, healthier brows over time.

Is MD Brow Conditioning Serum drug-free?

Yes. MD Brow is a cosmetic conditioning serum and does not contain bimatoprost, latanoprost, minoxidil, or any other drug. It uses peptide and botanical actives to condition the brow area without pharmaceutical ingredients.

Can I wear makeup over MD Brow Conditioning Serum?

Yes. Apply MD Brow to clean brows and allow it to absorb fully (a few minutes) before applying brow pencils, gels, powders, or any cosmetic product. The serum is non-greasy and will not interfere with makeup application.

Seeing Is Believing

Before MD Brow Conditioning Serum, eyebrows often appear sparse, fragile, and lack the definition needed to frame your face. This sparse look is often the result of age, environmental stressors, or over-tweezing.

The Visible Shift: With consistent nightly use, our physician-formulated serum provides deep nourishment that conditions brow hairs, for brows that look fuller, stronger, and more resilient. Individual results vary.

Experience a refined, youthful look with brows that reflect the science of MD®.
