What is MD Brow Conditioning Serum?

MD Brow Conditioning Serum is a physician-formulated daily serum by Dr. Susan Lin, M.D., designed to transform thin, sparse, or over-tweezed eyebrows. The peptide-based formula is dermatologist-tested, non-irritating, and engineered for visible results in as little as 8 weeks.

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

Yes. MD Brow is designed for thin, sparse, or over-tweezed eyebrows. While severely scarred follicles may not fully regrow, 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 thinning is often the result of age, environmental stressors, or over-tweezing.

The Clinical Shift: After consistent nightly use, expect a visible transformation. Our physician-formulated serum provides deep nourishment that supports the natural brow cycle, resulting in brows that are not only fuller-looking but significantly stronger and more resilient.

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