The FDA-studied active ingredient for slowing unwanted facial hair growth.
Eflornithine 12% is the same active ingredient found in Vaniqa, the only FDA-approved prescription cream specifically indicated for reducing unwanted facial hair in women. It works by slowing the growth process itself — not by removing existing hair, but by making new hair grow slower, finer, and less noticeable.

Eflornithine is the active ingredient in Vaniqa, the only FDA-approved prescription cream specifically developed for unwanted facial hair in women. It is an enzyme inhibitor — not a depilatory or hair remover. Rather than dissolving or pulling out hair, eflornithine works at the cellular level to slow the biological process that makes hair grow.
Originally discovered as an anti-parasitic medication, researchers found that eflornithine had a remarkable effect on hair growth. When applied topically at a 12% concentration, it inhibits a key enzyme in hair follicle cells, gradually causing facial hair to grow more slowly, come in finer, and become less visible over time.
Because it targets the growth mechanism rather than existing hair, eflornithine works best as a complement to your current hair removal method — whether that's shaving, waxing, threading, or laser treatments.

Eflornithine irreversibly inhibits ornithine decarboxylase (ODC), an enzyme essential for polyamine synthesis. Polyamines are required for cell division — including the rapid cell division that drives hair growth.
Without sufficient ODC activity, hair follicle cells can't divide as quickly. The follicle's growth phase (anagen) becomes less productive, resulting in hair that grows more slowly than before.
As the follicle's growth capacity is reduced, each successive hair cycle produces thinner, lighter, and less coarse hair. Over weeks of consistent use, the change becomes increasingly visible.
The combined effect of slower growth and finer texture means hair becomes progressively less noticeable. Many women find they need to remove hair less frequently over time.
Eflornithine doesn't remove existing hair. It slows new growth — making it a powerful complement to any removal method.
Best results come from combining approaches. Continue your preferred hair removal method while using eflornithine to slow regrowth. Over time, you may find yourself needing to remove hair less frequently as new growth becomes finer and slower.
Eflornithine has been studied in multiple clinical trials supporting its FDA-approved indication for facial hair reduction.
Eflornithine works gradually. Here's a realistic timeline of what most women experience.
Eflornithine begins working at the follicle level, but visible changes take time. Continue your normal hair removal routine. Some women notice skin feels smoother between removals.
Hair may begin growing back more slowly after removal. Some women notice hair feels finer or softer. You may start to notice longer intervals between hair removal sessions.
Most women see noticeable improvement during this period. Hair grows in thinner, lighter, and less frequently. The time between hair removal sessions increases noticeably.
Maximum benefit is typically reached by 24 weeks of consistent use. Hair growth is significantly slowed, and many women report a meaningful reduction in how often they need to address facial hair.
Wash and dry the areas where you'll apply the cream. If you've just removed hair (shaving, waxing, etc.), wait at least 5 minutes before applying to avoid stinging.
Apply a thin layer to the affected areas of the face, chin, and adjacent involved areas under the chin. Rub in thoroughly. A little goes a long way.
Apply twice a day, at least 8 hours apart. Most women apply once in the morning and once in the evening for best results.
Avoid washing the treated area for at least 4 hours after application. You can apply sunscreen or makeup over the cream once it's been absorbed (after a few minutes).
These typically resolve within the first few weeks as your skin adjusts. Applying after hair removal may temporarily increase stinging — waiting 5 minutes helps.
If irritation persists or worsens, reduce application to once daily or contact your provider. Discontinue use if you experience a severe reaction.
We offer two treatments that contain eflornithine. Here's how to decide which is right for you.
Eflornithine 12% is the same active ingredient at the same concentration as Vaniqa. Vaniqa is the brand name; eflornithine is the generic name. Our formulation delivers the same FDA-studied active ingredient.
Eflornithine is FDA-studied specifically for facial hair — the face, chin, and adjacent areas under the chin. It has not been well-studied for body hair (legs, arms, bikini area) and is not recommended for use on those areas.
Eflornithine slows hair growth only while you use it. If you stop, hair will gradually return to its previous growth rate and thickness over about 8 weeks. It does not cause rebound growth — hair simply returns to what it was before treatment.
Yes. In fact, combining eflornithine with laser hair removal has been shown in studies to produce better results than either treatment alone. Continue using eflornithine between laser sessions for optimal hair reduction.
Most women begin to see improvement within 4-8 weeks of consistent twice-daily use. Maximum results are typically reached after about 24 weeks. If you see no improvement after 4 months of consistent use, consult with your provider.
Yes. Wait a few minutes after applying eflornithine for it to absorb into the skin, then you can apply sunscreen, moisturizer, or cosmetics over the treated area as usual.
Eflornithine is considered safe for ongoing use. It is applied topically and very little is absorbed into the bloodstream. In clinical trials, side effects were generally mild and localized to the application area.
