Can You Get Botox and Filler at the Same Time? Everything You Need to Know

Quick summary: You can absolutely have Botox and filler injections at the same time in one treatment session, because the two methods work through different mechanisms and support each other. This combination optimizes the rejuvenating effect, both reducing wrinkles caused by muscle contraction and filling hollow areas, giving a more natural, plumper face. For the best results, you need to be examined in person by a doctor and follow the post-injection care instructions.

Can Botox and filler be used at the same time?

Yes, you can absolutely have Botox and filler in the same session at the clinic. The two work through different mechanisms, so they do not conflict and usually complement each other well. Botox reduces wrinkles caused by muscle contraction, while filler firms the skin by filling hollow areas or areas that have lost firmness.

How do Botox and filler work?

Botox is a substance injected into the facial muscles to relax them, helping reduce wrinkles and crow's feet around the eyes. (ASPS) Results start to appear within a few days; according to the manufacturer's prescribing information, results are assessed at week 4 after injection, and treatment should not be repeated more often than every 3 months.

Filler is a substance injected into the skin to:

• Fill deep dynamic and static wrinkles
• Increase firmness and radiance around the eye area
• Fill the cheeks and chin for a rounder face
• Lift the soft tissue layer of the face to reduce sagging

Filler results can be seen right after injection, but it takes a few weeks for swelling to subside completely and for results to become stable and most noticeable. The exact timeframe depends on each person's constitution, and your doctor will advise you during the examination.

Why is combining Botox and filler more effective?

Botox addresses movement (muscle contraction), while filler addresses volume and firmness. When you use both, you get:

• Better reduction of wrinkles and crow's feet
• A more natural-looking face, not stiff or overfilled
• A plumper, brighter, healthier-looking face
• Better "balanced" age appearance than using just one product

Everyone's skin and muscles are different, so your doctor will advise which treatment to use in which areas, or where to combine the two, for the most natural result.

What to keep in mind when having Botox and filler on the same day

If you decide to have both in one session, you should:

• Tell your doctor about any history of allergies or reactions to previous injectables
• Avoid alcohol, coffee, and medications that affect blood clotting for a few days beforehand
• After injection, avoid rubbing, pressing, or lying face down for the first 4 hours. (ASPS) For Botox specifically, avoid lowering your head, practicing yoga (especially headstands) for the first 24 hours, and avoid steam rooms or massage at the injection site for the first 3 days.
• Avoid exercise and overly hot environments for the first 24 hours. Botox starts to take effect within a few days and is fully assessed at week 4 (per the manufacturer's prescribing information); HA filler results are most noticeable after about 1 month.
• If you notice prolonged swelling, redness, or an allergic reaction, contact your doctor right away. WARNING specifically for filler: if the injected area turns pale or white, feels unusually cold, becomes very swollen or bluish-purple, or you have severe pain that does not subside after 24 hours (signs of vascular occlusion), contact your doctor IMMEDIATELY. (FDA; ASPS) If you notice blurred vision or any change in vision after a filler injection, this is an emergency — go to the clinic or the nearest medical facility immediately; do not wait. With Botox, rare signs that require you to notify your doctor immediately include ptosis (drooping eyelid), difficulty swallowing, or difficulty breathing. (ASPS)

Botox and filler are not "one size fits all." Everyone has different facial features, skin age, and goals, so a doctor needs to examine you and assess your case individually.

You may also need only one of the two treatments, or injections in just a few specific areas, rather than both. The doctors at BonBoz will help you create a plan that suits your face and aesthetic goals. Message or call us to schedule an examination and consultation.
