Eflornithine Cream (Vaniqa) for Facial Hair Removal

Key Takeaways

• Eflornithine cream slows unwanted facial hair growth by blocking an enzyme called ornithine decarboxylase (ODC) in hair follicles, but it does not remove existing hair.

• In clinical trials, 58% of women saw noticeable improvement after 24 weeks, compared to 34% with placebo.

• Results typically become visible within 8 weeks, and if no improvement is seen after 6 months of consistent use, talk to your provider about alternatives.

• Combining eflornithine with laser hair removal leads to complete or near-complete hair removal in 93.5% of cases, compared to 67.9% with laser alone.

• Side effects are generally mild. Acne (up to 21%) and minor skin irritation are most common, and only 2% of users stop treatment because of side effects.

Eflornithine cream works. In clinical trials, it slowed the growth of unwanted facial hair in up to 60% of women (1, 2). It won't remove hair permanently, and it requires consistent twice-daily application, but for women dealing with excess facial hair, it is one of the few topical prescription treatments that actually does what it claims.

In clinical practice, I usually frame this as a “hair growth reducer,” not a hair removal treatment, so expectations are clear from the start.

The cream works by interfering with an enzyme your hair follicles need to grow. Over time, the hair comes in slower and finer where you apply it. This makes it a useful option for women with hirsutism (excess facial hair), including those affected by polycystic ovary syndrome (PCOS), and it appears to work regardless of whether the hair growth is hereditary or caused by a hormonal condition (1).
