The Science of Brow Conditioning
Eyebrows go through a natural growth and shedding cycle, similar to lashes. Over-tweezing, age, and stress can disrupt this cycle, leaving brows thin and sparse. MD® Brow Conditioning Serum is designed to support this cycle at the brow follicle through a gentle, daily-use formula.
How to use: Apply once daily to clean, dry brows with the precision applicator. Allow to absorb fully before applying makeup or other brow products. For best results, use consistently for at least 8 weeks.
What to expect: User-reported improvements typically begin around the 8-week mark in the 56-day study. Brows appeared thicker, more conditioned, and healthier-looking. Individual results vary.
Discontinuation: Brow condition is supported through continued use. Discontinuing application may result in a gradual return to your natural baseline brow appearance.

Can I use MD® Brow after microblading?
