Key ingredients
| Trifolium Pratense (Clover) Flower Extract | Supplies a red-clover botanical in the brand's brow-support complex; regrowth from this serum is unproven. |
|---|---|
| Myristoyl Pentapeptide-17 | Adds a second peptide-based hair-support pathway through the SymPeptide complex. |
| Keratin | Adds protein-based conditioning for existing brow hairs. |
| Panthenol | Adds conditioning and flexibility support. |
| Sodium Hyaluronate | Adds water-binding support to the brow-line skin. |

Value check
At the Premium tier, you get several conditioning peptides and botanical extracts, without proven superiority over simpler brow serums.
Bottom line
If your brows are fragile, Thick + Full offers a peptide-rich way to condition existing hairs. Its Premium price is harder to justify for regrowth, which this finished serum has not clinically demonstrated.
If your eyebrows look sparse or fragile, Beverly Hills MD Thick + Full Brow Enhancing Serum combines peptide ingredients, glycerin, panthenol, keratin and botanical extracts to condition existing brow hairs. The brand describes it as prostaglandin-free, which distinguishes its approach from prescription bimatoprost and some prostaglandin-analogue cosmetics.[1]
Its ingredient system has a credible conditioning rationale, but the public product evidence does not show that it increases eyebrow hair counts or reliably regrows missing brows.
What it claims
Beverly Hills MD says twice-daily use helps sparse brows look fuller, thicker, more uniform, and better defined. The brand highlights Redensyl®, Capixyl™, and SymPeptide™ and says the serum supports healthy hair while nourishing the skin underneath. The current formula is also positioned as free of hormones and prostaglandins.[1]
Claims vs. formula
The conditioning story is well aligned with the formula. Glycerin and sodium hyaluronate add humectant support, panthenol supports flexibility and conditioning, and keratin plus keratin amino acids provide protein-based support for existing brow hairs.[1]
The growth-support story is more nuanced. Capixyl™ is represented by acetyl tetrapeptide-3 plus red clover extract, while Redensyl® contributes larch extract, green tea, glycine, and zinc chloride, and SymPeptide™ contributes myristoyl pentapeptide-17. A randomized scalp-hair study of an herbal complex containing acetyl tetrapeptide-3 and biochanin A reported hair-growth benefits, but that study was conducted in androgenetic alopecia and did not test this Beverly Hills MD eyebrow serum.[2]
That makes ingredient-level plausibility different from finished-product proof. The current public page provides customer testimonials and third-party quality-testing language, but no controlled human eyebrow trial with standardized hair counts or measured density change.
The formula contains PEG-12 dimethicone, so BB applies the Silicone Formula Flag for transparency. It does not contain prostaglandins, fragrance, essential oils, retinoids, or exfoliating acids that require additional controlled Formula Flags.
Ingredients that matter
Myristoyl Pentapeptide-17 and the red-clover extract Trifolium Pratense (Clover) Flower Extract form part of the brand’s brow-support story. The official list spells another peptide as “Acetyl Tretrapeptide-3”; that spelling should be checked against your packaging rather than assumed to identify a different compound.
Keratin, panthenol, glycerin and sodium hyaluronate make a plausible conditioning base for existing brow hairs. Evidence from scalp-hair studies of different formulations does not demonstrate new eyebrow growth from this particular serum.
Panthenol
Panthenol is a well-supported humectant and conditioning ingredient that improves hydration and helps reduce water loss. The complete moisturizer matters more than a high percentage or broad barrier-repair marketing.

Hyaluronic Acid
If your skin feels dry or tight, hyaluronic acid helps your skin hold moisture. You don't need several HA forms or a separate serum when your moisturizer already hydrates well.
Read the IngredientBriefWhat to expect in the short term
Expect a lightweight, non-oily conditioning layer rather than an immediate growth effect. Beverly Hills MD directs users to apply the serum to clean brows morning and night, concentrating on sparse areas while coating both the brow hairs and the skin underneath, then allowing it to dry before makeup.[1]
In the short term, the most realistic benefit is better-conditioned brow hair with improved grooming, softness, and reduced brittle feel.
What to expect over time
Consistent use can reasonably help existing brow hairs look healthier, fuller, and more uniform if conditioning reduces breakage and improves the appearance of individual strands. The peptide and botanical complexes add a plausible hair-support rationale, but the current public evidence does not establish clinically meaningful follicular regrowth or a predictable increase in eyebrow hair count.
For context, controlled eyebrow-hypotrichosis studies exist for agents such as bimatoprost and topical minoxidil, including randomized trials with measured changes in eyebrow fullness, diameter, and hair number.[3] Those data do not transfer to this cosmetic serum; they simply show what stronger eyebrow-growth evidence looks like.
Who it fits
If you want your existing eyebrows to feel conditioned and look less brittle, a prostaglandin-free serum may fit your preferences. If your brows are becoming patchy or thinning unexpectedly, a medical assessment can help identify causes that cosmetic conditioners cannot treat.
Beverly Hills MD declares its formulas cruelty-free. The presence of keratin does not provide sufficient evidence for a vegan attribute.
Compare before you buy
The Ordinary Multi-Peptide Lash and Brow Serum is the most useful lower-cost comparison because it uses several overlapping pathways: myristoyl pentapeptide-17, acetyl tetrapeptide-3, larch extract, red clover extract, green tea, panthenol, glycine, and zinc chloride. It is also prostaglandin-free, silicone-free, vegan, and cruelty-free, and comes in a larger 5 mL format.[5]
That overlap makes Beverly Hills MD’s Premium-tier value harder to defend purely on formula differentiation. Thick + Full adds keratin, keratin amino acids, castor oil, biotin, and several additional botanicals, but the brand does not publish finished-product eyebrow-growth data showing that those additions produce a superior outcome.
Final Assessment
If your brows look sparse because hairs are fragile, Thick + Full offers a peptide-and-conditioner blend to support their appearance. The finished serum has no controlled human evidence showing new eyebrow regrowth. Its Premium value is weaker than a simpler conditioning alternative if proven growth is your main goal.
