FLASHSERUM Eyebrow Serum for Fuller, Bolder Brows — 3 mL Precision Applicator, Vegan

If you want naturally more defined eyebrows without tinting or microblading, fLASH provides a daily topical treatment to nourish and strengthen existing brow hairs. The lightweight 3 mL applicator delivers a precise stripe of serum along the brow line so you can concentrate product where you need coverage most. This vegan, cruelty-free formula is made in the USA and created with sensitivity in mind, making it suitable for many people who wear contact lenses or have delicate eye skin.

How quickly will I see a visible difference in my brows?

Most users notice initial changes within 4–6 weeks, with fuller-looking results developing through 8–12 weeks of consistent use. Results vary by individual depending on natural hair cycle, baseline density, and application consistency.

• Initial improvements often at 4–6 weeks.
• Fuller-looking brows typically by 8–12 weeks (60–90 days).
• Daily application yields the fastest visible progress.
• Consistency matters—use until desired look is achieved.

What is the correct way to apply the serum for best results?

Apply a thin line directly along the brow line, targeting sparse areas and ensuring the applicator tip contacts the skin. Allow the serum to dry 2–3 minutes before applying other cosmetics; a little product goes a long way so remove any extra from the tube tip before use.

• Glide a thin stripe along the skin at the brow base.
• Focus on gaps or thinning sections for targeted conditioning.
• Dry time 2–3 minutes before makeup layering.
• Do not apply to eyelashes; for brows only.

Is this safe for sensitive eyes and contact lens wearers?

Yes — fLASH was formulated to be gentle for sensitive eye areas and contact lens users. If you have very reactive skin, start every other day for the first 10 days to check tolerance and stop use if irritation occurs.

• Suitable for sensitive skin and eyes in most users.
• Safe with contact lenses when used as directed.
• Patch-test recommendation: every other day for 10 days if sensitive.
• Discontinue immediately if irritation develops.

How long does one 3 mL tube last and what support is offered?

A single 3 mL tube is formulated to provide approximately a three-month supply when used as directed, because only a small amount is needed for each application. fLASH offers a 90-day satisfaction focus — contact the US-based customer team for assistance if expectations aren’t met.

• 3 mL (0.1 fl oz) intended as about a 3-month supply.
• Concentrated formula: small daily amount per brow.
• 90-day customer support for product satisfaction questions.
• Made in the USA, cruelty-free and vegan.

Who is this for? fLASH Eyebrow Serum is suited to anyone wanting naturally stronger-looking, more defined eyebrows without cosmetic tattooing or heavy makeup—especially helpful for people with sparse areas, overplucked brows, or those seeking thicker-looking results while maintaining a gentle formula for sensitive eyes. It’s not a lash product—use only as directed along the brow line. If you have medical concerns about topical products near the eye, consult your healthcare provider before starting.
