Frequently Asked Questions

About the Practice

  • All treatments are performed by me, Anastasia Bevza, FNP-BC, a board-certified Family Nurse Practitioner licensed in Washington, DC, Virginia, and Maryland.

  • Naas Tox & Skin is a small clinician-run practice where the primary aesthetic treatment tool is neurotoxin. There are no fillers, no lasers, and no pressure to “level up” into packages of procedures.

    My goal is simple: thoughtful treatment planning that respects your face and your comfort level. Small adjustments and modest goals are completely valid here.

    If something outside of Naas Tox would better fit your goals, I’m happy to point you in the right direction.

  • Yes.

    Neurotoxin treatments are medical procedures. I review medical history, obtain informed consent, and provide follow-up when needed. The same applies to clinical skin consultations and prescribing practices.

Safety

  • Botulinum toxin has been used medically for decades and is considered very safe when administered by trained medical professionals.

  • I do not treat patients who are pregnant or breastfeeding, and treatment may not be appropriate for individuals with certain neurological conditions. Your medical history is reviewed before treatment to make sure it is appropriate.

  • Common temporary reactions include mild redness, swelling, or small bruises at injection sites.

    Rare side effects can occur and will be discussed during your consultation. Follow-up care is always available if anything unexpected arises.

Appointments

  • All new patients begin with a consultation. In many cases, treatment can be done the same day if appropriate.

  • Often yes. If time allows and there are no medical concerns, treatment can usually be performed immediately after your consultation.

  • Most appointments take about 30 minutes. Follow-up visits are usually shorter.

Results

  • If you want frozen — I can do frozen.

    But most patients today prefer softer expression lines while keeping natural movement. Most people end up looking refreshed rather than noticeably treated.

  • Very subtle. Many patients simply want to soften certain expression lines while preserving natural movement.

    The goal is not to eliminate expression but to relax muscles enough to reduce the lines they create.

  • Results usually begin appearing within 3–5 days, with full effect at 10–14 days.

    Tox patience is a short but useful life skill.

  • If it’s been about two weeks and you’re not seeing the expected result, reach out. I include follow-up for exactly this reason.

    We’ll reassess the outcome and, if needed, make adjustments. Thoughtful dosing sometimes means starting conservatively and refining once the medication has fully settled.

    The goal is a balanced result — not a one-shot guess.

  • For cosmetic treatments, results typically last about 3–4 months.

    For treatments such as excessive sweating (hyperhidrosis), results often last closer to 6 months.

    It is safe to repeat cosmetic treatments about every 3–4 months when appropriate.

    Most patients maintain results with periodic treatments rather than waiting for everything to fully wear off.

  • First things first — tell me. I want to hear about it and keep communication open.

    The first 10 days after treatment can be the trickiest because the medication is still settling. Occasionally unintended effects occur, and if that happens I will work with you on managing the situation.

    There is no medication that instantly reverses botulinum toxin, but the effects are temporary and gradually fade over time. Long-term problems from cosmetic neurotoxin treatments are extremely rare.

    I intentionally treat conservatively, especially with first-time patients. Follow-up visits are recommended and included so we can reassess once the treatment has fully settled.

  • Photos can be helpful for understanding aesthetic preferences, but faces, anatomy, and muscle patterns differ from person to person.

    My goal is to create results that work for your face, rather than reproducing someone else’s.

  • Treatment planning is based on facial anatomy and muscle activity rather than a preset number of units.

    Previous treatment records are always helpful, but dosing decisions are ultimately made during consultation to achieve the safest and most balanced result.

  • For underarm treatments, a light trim is helpful so the area is easier to see and treat evenly. If you prefer shaving, do it 24–48 hours beforehand to avoid irritation.

Pricing

  • Pricing is set per treatment area and includes the units needed for a thoughtful, balanced result.

    My goal is transparent, predictable pricing rather than upselling — or skimping — on those precious units.

  • Most treatments are priced per treatment area, with the exact number of units determined during consultation.

    I want you to relax and let me worry about these details — the same way you would when I prescribe an antibiotic or adjust a medication dose.

  • A brief follow-up visit is encouraged 10–20 days after treatment to evaluate results and make small adjustments if needed.

  • Yes!

    Patients treated with Jeuveau® can enroll in the Evolus Rewards program, which allows you to accumulate points that convert into credits toward future treatments. Many patients find it works a bit like a well-behaved coupon that quietly lowers the cost of maintenance treatments over time.

    Enrollment is free and takes only a minute through the Evolus Rewards mobile app. If you’re interested, I’m happy to walk you through it during your visit.

  • Occasional announcements or promotions are shared on Instagram at @naastoxandskin.

Neurotoxin Product

  • At this time I focus on a single toxin product in order to maintain consistency in dosing, treatment planning, and results.

    Different neurotoxin brands have different dosing units and diffusion characteristics. Working with one product allows for more predictable outcomes and clearer long-term treatment planning.

  • I currently use Jeuveau®, an FDA-approved botulinum toxin developed specifically for aesthetic use.

    Like other neurotoxins, it temporarily relaxes targeted facial muscles that create expression lines. In clinical use it performs very similarly to other established toxin products.

    In aesthetic medicine, results depend far more on injection technique and treatment planning than on the specific brand used.

    In other words: it’s not the tox — it’s what you do with it.

  • No.

    I am not sponsored by Evolus or any pharmaceutical company. Product selection is based on clinical experience, product performance, and practical considerations within the practice.

Clinical Skin Visits

  • A clinical visit focuses on practical, evidence-based skin care.

    During the visit we review your skin concerns, current routine, medical history, and treatment goals. I may recommend prescription treatments, over-the-counter options, and a realistic routine.

    You will leave with a plan that may include prescription options and an OTC regimen.

  • Yes, when clinically appropriate.

  • Skin care often sounds simple, but even basic treatments benefit from a proper evaluation.

    During a visit, we review your concerns, current routine, and goals before deciding what’s appropriate. In some cases that may include prescription treatment, but the goal is a plan that actually works — not just a quick prescription.

  • That’s great.

    These visits are not meant to replace dermatology care. Sometimes people simply want help understanding their options or simplifying their routine. If helpful, you can bring records from your dermatologist to the visit.

  • For now skin visits are in person only.

    In the future I plan to offer telemedicine visits.

  • I usually provide paper prescriptions so you have flexibility in how and where you fill them.

    Insurance coverage for topical medications is often limited — especially for off-label use, which is common in practical skin care. Many newer branded medications can be expensive and inconsistently covered.

    In most cases, I focus on well-studied, off-label or generic options that are effective and more accessible. Tools like GoodRx can often help reduce cost at the pharmacy.

    If you have a preferred pharmacy or approach, we can work with that.

  • Skin Medicinals is a compounding pharmacy that creates customized topical treatments.

    This is often the most efficient way to combine ingredients that would otherwise require multiple prescriptions — for example, retinoids, pigment agents, and anti-inflammatory medications — into a single, well-formulated product.

    In practice, this can simplify your routine, improve consistency, and often work better than layering multiple separate products.

    These formulations are typically self-pay, but many patients find them more practical and cost-effective overall compared to juggling multiple prescriptions.

    I recommend Skin Medicinals when it meaningfully improves the plan — not by default.

  • In general, I focus on treatments that are well-studied, practical, and accessible.

    Many newer branded medications are expensive and not consistently covered by insurance. When there is a clear benefit, we can discuss them — but most treatment plans rely on established, effective options rather than chasing newer products.

  • Cost is part of the plan.

    I pay attention to medication pricing and coverage when making recommendations — because if something isn’t practical to obtain or maintain, it doesn’t work.

    Most effective treatments are available as generics or through tools like GoodRx.

    Compounded formulations (such as Skin Medicinals) are typically $55–85 per bottle and often replace multiple separate products.

    We can adjust the plan based on your preferences and budget.

  • Skin care changes take time.

    Unless there are side effects or concerns, follow-up is usually recommended around 2–4 months to reassess progress and adjust the plan if needed.

Logistics

  • Appointments are typically performed at Arte Dental in Washington, DC. Limited mobile appointments may also be available.

  • Yes, limited mobile appointments may be available in certain circumstances.

  • Mobile visits are typically arranged for small groups or private appointments in homes, offices, or events.

    The same consultation, consent, and treatment process applies — just in a different setting. I bring the necessary clinical supplies and maintain the same clean and aseptic technique used in a medical office.

  • Appointments require advance notice to cancel or reschedule. Details are provided during booking.

  • Sometimes — though I prefer to think of them as small group appointments rather than parties.

    Neurotoxin injections are still medical procedures. Each person receives an individual consultation and must provide clear consent.

    A relaxed gathering with a few friends can work well. A crowded party atmosphere usually does not.
