If you have been researching eyelash growth serums, you have probably seen Latisse — the heavily marketed brand-name product that typically costs $120–180+ per month. What the marketing does not tell you is that Careprost contains the exact same active ingredient (Bimatoprost 0.03%) at a fraction of the price, delivering the same lash growth results.
This article breaks down the facts: what Bimatoprost is, how it works, and why Careprost and Latisse produce equivalent results — so you can make an informed decision and stop overpaying for a brand name.
Bimatoprost 0.03% is the active ingredient in both Careprost and Latisse. It was originally developed for a different purpose, but researchers discovered it had a remarkable cosmetic benefit: patients experienced significantly longer, thicker, and darker eyelashes. Today, bimatoprost-based lash serums are the only clinically proven topical products that genuinely stimulate new eyelash growth (as opposed to OTC serums that merely condition or nourish existing lashes).

Latisse is a branded product with significant marketing costs built into the price — TV ads, magazine placements, dermatologist promotions. Careprost and Bimat contain the same active ingredient manufactured to the same standards, without the branding markup. The difference is price, not quality or effectiveness.
Every eyelash goes through a natural growth cycle: active growth, transition, and rest. After the rest phase, the lash falls out and a new one grows. Bimatoprost works by extending the active growth phase, giving each lash more time to grow before shedding. It also stimulates more lash hairs to grow during each cycle and enhances natural pigment, making lashes appear darker and more defined.
Remove all makeup and contact lenses. Place one drop on the applicator brush. Draw the brush along the base of the upper lash line (like liquid eyeliner). One drop per eye. Apply once daily at bedtime. Do not apply to lower lashes — the product transfers naturally through blinking. Contact lenses can be reinserted after 15 minutes.
Weeks 2–4: Subtle early changes. Lashes may feel slightly stronger.
Weeks 4–8: Noticeable improvement in length, thickness, and darkness.
Weeks 8–16: Full results. Many users no longer need mascara.
Maintenance: Once desired length is achieved, reduce to 1–2 applications per week.
Both contain Bimatoprost 0.03% and deliver the same lash growth. The difference is tolerability: Bimat tends to cause less eye redness and irritation, making it a better choice for sensitive eyes. Careprost is the established #1 bestseller with nearly 500 reviews and a proven track record.
Our recommendation: try Bimat if you have sensitive eyes or are a first-time user. Go with Careprost if you want the tried-and-true customer favorite.
Q: Is Careprost really as effective as Latisse?
A: Yes. Same active ingredient (Bimatoprost 0.03%), same mechanism, same results. The only difference is branding and price.
Q: Will my lashes stay long if I stop?
A: Lashes gradually return to their natural length over several weeks if you stop completely. Most users maintain results with 1–2 weekly applications.
Q: Are there side effects?
A: Possible mild itching at the application site. Rarely, darkening of the eyelid skin (reversible upon stopping). Bimat causes less eye redness than Careprost for sensitive users.
Q: Can I use this with Eflora Cream?
A: Yes. Many customers use a lash growth serum alongside Eflora (for unwanted facial hair) as a complete beauty enhancement routine. The products do not interact.
