Unwanted facial hair can be more than a cosmetic nuisance—it can affect confidence, daily routines, and quality of life. Eflornithine HCl 13.9% cream, available for fast digital prescribing through eNavvi, offers a clinically proven, prescription‑strength way to slow hair growth and extend the smooth interval between hair‑removal sessions.
What Is Eflornithine HCl 13.9% Cream?
Eflornithine is a topical medication formulated at 13.9% strength. Unlike depilatories that dissolve hair shafts or lasers that target follicles with heat, eflornithine works inside the follicle to reduce the rate and coarseness of new hair growth—making it an ideal adjunct to shaving, waxing, threading, or laser therapy.

How Does Eflornithine Work?
Mechanism of Action
Hair shafts grow when follicles produce the structural protein keratin, a process that relies on polyamines—small molecules synthesized by the enzyme ornithine decarboxylase (ODC). Topical eflornithine is a selective, irreversible ODC inhibitor:
Blocks polyamine synthesis inside the hair bulb.
Slows keratin assembly and cell division in the follicle matrix.
Extends the anagen (growth) phase, reducing the speed and thickness of emerging hair.
The result is finer, slower‑growing hair that requires less frequent removal. Because eflornithine does not destroy follicles, growth gradually returns to baseline about eight weeks after discontinuation.
Who Benefits Most?
Ideal Candidates
Women bothered by unwanted facial or submental hair (e.g., hirsutism, PCOS)
Patients seeking a non‑laser option for darker skin phototypes
Those using laser/IPL who want to extend treatment intervals
People experiencing irritation from frequent waxing or depilatories

When Not to Use Eflornithine
- Known hypersensitivity to eflornithine or cream excipients
- Broken, inflamed, or infected skin in the application area
- Children (< 12 years): safety not established
- Pregnancy: Category C—use only if anticipated benefits outweigh potential fetal risk
- Breastfeeding: Insufficient data; exercise caution and avoid application near the nipple area
Always discuss systemic conditions (e.g., severe acne, dermatitis), concurrent topical treatments (retinoids, benzoyl peroxide), and hair‑removal methods with your prescriber.
Dosage & Application Guide
Prep the skin: Remove hair by your usual method (shave, wax, etc.) and wait ≥ 5 min.
Clean & dry: Gently cleanse, pat dry.
Apply a thin film: Use pea‑sized dabs to cover only affected areas (avoid eyes, mouth, mucous membranes). Rub in until absorbed.
Frequency: 2× daily, morning & evening, at least 8 h apart.
Post‑application care: Avoid washing, swimming, or sweating heavily for 4 h after application.
Cosmetics: Makeup or sunscreen may be applied after the cream dries (~ 5 min).
If no clinical improvement is observed after 6 months, reassess therapy.
Expected Timeline
- Weeks 0‑4: Subtle reduction in stubble feel; less five‑o‑clock shadow.
- Weeks 4‑8: Noticeable slowdown in regrowth; hairs appear finer.
- Months 3‑6: Peak effect; many users can shave/wax half as often.
- > 6 months: Continue maintenance if satisfied; discontinue if inadequate response.
Stopping treatment leads to gradual return to baseline hair density within ~ 8 weeks.
Possible Side Effects
Most reactions are mild and limited to the skin surface:
- Transient burning or stinging at application site
- Redness, dryness, or itching
- Acneiform eruptions or folliculitis
- Tingling or rash
- Contact dermatitis (rare)
Management tips: Use a gentle cleanser, avoid alcohol‑based toners, and apply non‑comedogenic moisturizer if needed. Discontinue and consult a clinician if severe irritation or allergic rash develops.
Systemic absorption is < 1%, so systemic side effects are exceedingly rare.
Best‑Practice Tips for Clinicians
- Combine eflornithine with laser or IPL for synergistic results—slowing regrowth lets energy‑based treatments target fewer, slower‑cycling follicles.
- Consider hormonal evaluation (androgen levels, PCOS work‑up) for women with rapid, coarse facial hair.
- Document baseline photography; objective visuals help motivate adherence and gauge progress.
- Remind patients that consistency is key—twice‑daily use is required for optimal suppression.
