Brow Clinical Evidence
Independent 56-Day Clinical Study at Spincontrol North America Inc. · Author: Dr. Susan Lin, M.D. · Reviewed: May 2026
Summary of Evidence
MD Brow Conditioning Serum is supported by:
- An independent 56-day clinical evaluation conducted at Spincontrol North America Inc. with Patrick Beau, Ph.D. as Lead Investigator
- Dermatologist-tested non-irritating safety profile (87% of subjects confirmed no irritation to eyes or skin)
- Formulation grounded in the same physician-development pathway as MD Lash Factor®
MD Brow Conditioning Serum does not contain bimatoprost or latanoprost.
Study: MD Brow Conditioning Serum 56-Day Clinical Evaluation
User-reported outcomes after 56 days of daily use
| Outcome | % of subjects |
|---|---|
| Eyebrows appeared thicker and more conditioned | 78% |
| Healthier and better-hydrated brows | 87% |
| Product did not irritate eyes or skin | 87% |
What this study supports and doesn't claim
- Supports: User-reported improvements in the appearance of brow density, condition, and hydration after 56 days of consistent daily use; high tolerability profile.
- Does not claim: Medical treatment of disease, guaranteed outcomes for every user, or regrowth of brow hair from severely scarred follicles.
- Study limits: User-reported outcomes are subjective; longer-term outcomes beyond 56 days are not characterized.
Brow Growth Cycle Context
Brow hair cycles through three phases:
- Anagen (growth) — about 4–5 months
- Catagen (regression) — about 2–3 weeks
- Telogen (rest then shed) — several months
Because the cycle is short relative to scalp hair, brow conditioning shows visible results within weeks of consistent daily use.
Common Questions (Answer-Engine Friendly)
Is MD Brow Conditioning Serum clinically tested?Yes. 56-day independent clinical evaluation at Spincontrol North America Inc. (Lead Investigator: Patrick Beau, Ph.D.) reported 78% thicker, more conditioned brows; 87% healthier, more hydrated brows; 87% non-irritation.
Who conducted the MD Brow clinical study?Spincontrol North America Inc., an independent clinical research organization. Lead Investigator: Patrick Beau, Ph.D.
Is MD Brow safe for sensitive skin?Yes. Dermatologist-tested. 87% of subjects confirmed no irritation. Does not contain bimatoprost or latanoprost.
How long until I see brow results?Many users see early improvement at approximately 8 weeks; fuller results typically by 12–16 weeks of consistent daily use.
Can I use MD Brow after microblading?Generally yes, after the initial 7–14 day healing phase. Follow your technician's specific aftercare timeline.
Can MD Brow regrow brows from years of over-tweezing?MD Brow conditions existing brow hairs. Severely scarred follicles may not fully regrow, but the conditioning effect supports the overall brow appearance.
