20 Units of Botox Before and After

Botox has become one of the most popular ways to reduce wrinkles and keep your skin looking smooth and youthful. Many people wonder what 20 units of Botox can do and what results they can expect. If you are thinking about getting Botox, this guide will explain everything in simple words. We will cover what 20 units of Botox is, what areas it can treat, how it works, what you will see before and after, and what to expect during recovery.

By the end, you will have a clear idea of whether 20 units of Botox is right for you.


What Are 20 Units of Botox?



Botox is a safe and effective treatment made from a protein that temporarily relaxes muscles. When muscles relax, the skin above them smooths out.


A "unit" of Botox measures the strength of the injection. Most patients receive between 10 and 50 units, depending on the area being treated. Twenty units is a common amount for treating moderate lines on the forehead, crow’s feet near the eyes, or frown lines between the eyebrows.


  • Forehead lines: Smooth horizontal lines caused by raising eyebrows.

  • Crow’s feet: Small wrinkles at the corners of your eyes when you smile.

  • Frown lines: Lines between the eyebrows caused by frowning or concentrating.


Using 20 units is usually enough to achieve natural-looking results without over-treating the area.


What to Expect Before Treatment


Before your Botox appointment, the clinician will evaluate your skin and facial structure. This step is important to make sure you get the right results.


Tips to Prepare:

  • Avoid blood thinners: Medications like aspirin can increase bruising.

  • Skip alcohol: It can make your skin more likely to bruise.

  • Discuss your health: Share your medical history and any allergies with your provider.

  • Plan the treatment area: Your clinician will decide how many units you need and where to inject.


This preparation helps ensure a smooth procedure and natural-looking results.


The Botox Procedure


The actual Botox injection is quick and simple. Most sessions take only 10–20 minutes.


  • Cleaning the skin: The clinician cleans the area with an antiseptic to prevent infection.

  • Marking injection points: Small marks may be made on your skin to guide the injections.

  • Injecting Botox: A tiny needle delivers small amounts of Botox to the muscles. Most people feel only a small pinch.

  • Finishing: There is no bandage required, and you can go home immediately.


Botox does not require anesthesia, and the procedure is usually painless.


20 Units of Botox Before and After: What You Will See


After getting 20 units of Botox, you may notice changes gradually. Most results appear within 3–7 days, with full results visible in 2 weeks.


Before Botox


  • Lines and wrinkles are visible when you make facial expressions.

  • Skin may look tired or aged.

  • Common areas include the forehead, frown lines, and crow’s feet.


After Botox


  • Forehead lines become smoother.

  • Crow’s feet soften and may disappear completely.

  • Frown lines are less noticeable, giving a more relaxed and youthful look.

  • Results look natural, not “frozen,” when done by a skilled clinician.


Tip: Always look at real before and after photos from a reputable clinic to understand what to expect.


Recovery and Aftercare


Recovery from Botox is simple and quick. Most people return to daily activities right away.


What to Expect:

  • Mild redness or swelling: Usually goes away in a few hours.

  • Small bruises: Rare but possible; can be covered with makeup.

  • Avoid rubbing the area: For at least 24 hours to prevent Botox from spreading to unwanted muscles.

  • Stay upright: Avoid lying down for 4–6 hours after treatment.

  • No strenuous exercise: For the first day, to ensure proper absorption.


Most patients can resume work or school immediately.


How Long Do Results Last?


Results from 20 units of Botox generally last 3–4 months.


  • Over time, muscles gradually regain movement.

  • Lines and wrinkles slowly return, and touch-up treatments may be needed.

  • Maintaining regular treatments can keep your skin smooth and youthful.


Safety and Side Effects


Botox is FDA-approved and safe when administered by a licensed professional. Common side effects are usually mild:


  • Temporary redness or swelling at the injection site

  • Minor bruising

  • Mild headache (rare)


Serious side effects are extremely rare. Choosing a trained and experienced clinician greatly reduces any risks.
