BIYSBER Eyebrow Serum with Hyaluronic Acid

On-body feel

For someone trying to care for sparse, thin, patchy, or over-plucked brows, this serum is designed to fit into a regular grooming routine rather than cover gaps with makeup.

Its formula is described as lightweight and non-sticky, with no greasy feel. Hyaluronic acid, aloe, centella, rosemary, and panax ginseng are included for moisture care, while peptides and biotinoyl tripeptide-1 are intended to condition brow hairs.

The doe-foot applicator traces the brow line for controlled coverage. After cleansing, apply it to dry brows, let it dry for 60 seconds, then continue with your routine. If you use brow makeup, the wait gives the serum time to dry first. It can also be used as an eyelash primer before daily makeup.

Pros

• The twice-daily directions are straightforward: apply to clean, dry brows in the morning and at night.
• The formula is fragrance-free, vegan, and cruelty-free, and is described as suitable for all skin types, including sensitive skin.
• The applicator is made for tracing the brow line, which offers a more targeted approach than spreading a general moisturizer over the area.
• It is labeled as a three-month supply, and the product description says consistent use may support fuller- and thicker-looking brows. The stated improvement timeline is as little as four weeks, but that is a product claim, not a guaranteed result.

A useful distinction: a brow pencil or powder can create an immediate filled-in look, while this serum is intended as ongoing conditioning care. Would you rather add a daily step than rely only on makeup to make brows look more defined? That choice is the main reason to consider this format.

You’ll appreciate it if you want a non-sticky conditioning step for brows that look sparse or uneven, and you’re willing to apply it consistently. The product also makes sense if you want one formula that can be used as an eyelash primer before makeup. From the way it is set up, the benefit depends on making it part of a routine, it is not a quick-fill product for days when you want an immediate change in brow definition.

Is it worth it?

This is a reasonable format to consider if your priority is daily brow care with a targeted applicator and a formula that also serves as an eyelash primer. Its fragrance-free formula and stated suitability for sensitive skin may matter if those are priorities for you, though the description does not provide ingredient concentrations or individual sensitivity results. Better avoided if you want instant coverage, do not want a twice-daily step, or need evidence of a specific result for your brows. The product’s own timeline is not a promise that every user will see fuller-looking brows in four weeks.
