Botox Injections San Diego at Lanoi
Botox San Diego
You keep catching the same lines in photos. Not deep, not dramatic, just there. And, the frustrating part is that when your face is totally relaxed, those lines make you look tired or annoyed, even when you feel completely fine.
What stops most people is not the lines. It is the fear of ending up looking done. Everyone can picture the frozen forehead and the surprised brow after getting a Botox injection, and nobody wants that.
You should be able to look like yourself. Not younger, not different, just refreshed/rested. That comes down almost entirely to who is doing your injections.
When you search for Botox San Diego, you’ll see a lot of choices. But what makes Botox injections at Lanoi Dermatology different is every injection is done by a board-certified dermatologist, Hannah Berman, MD.

What Is Botox?
Botox is a purified protein called botulinum toxin type A. It goes into specific facial muscles in very small amounts, and it softens the lines those muscles make. Doctors have used it since the 1980s, first for eye muscle problems. The FDA approved it for cosmetic use in 2002. It is now one of the most studied cosmetic treatments in the world.
Botox treats dynamic lines, the ones that appear when your face moves. It does not fill, lift or resurface. If a line sits there when your face is completely still, that is a static line, and a filler or a laser does more for it than Botox can.
The Mechanism
How Does Botox Work?
Your facial muscles move because a nerve tells them to. That signal rides on a chemical called acetylcholine. Botox blocks it right where the nerve meets the muscle. The muscle stops receiving the instruction, so it relaxes. With the muscle no longer folding the skin above it, the line softens and gradually smooths out.
The effect is temporary and local. Only the muscles that got the injection change. Over three to four months your nerves build new connections, the signal comes back, and so does your movement.
There is a second benefit people miss. A muscle that stops creasing the skin for months stops deepening the line under it. Treating a line while it still moves is what keeps it from etching in.
Treatment Areas
What Does Botox Treat?
Botox softens wrinkles that come from muscle movement. Four areas carry FDA approval for cosmetic use, and it is used for several more. Here is each one, what causes the wrinkle, and what Botox can and cannot do about it. How much you need is set at your consultation, because it depends on your own unique situation and facial muscles.
Botox also treats heavy underarm sweating, jaw clenching and chronic migraine. Those sit outside the cosmetic injections and need their own conversation. Botox injections San Diego patients book at Lanoi are all placed by Dr. Berman herself.
HOW THEY COMPARE
Botox vs Dysport vs Xeomin
All three relax the same muscles. They are made slightly differently, and the units are counted differently, so the numbers do not carry over between them. Lanoi Dermatology uses Botox. It is the only one FDA approved for all four treatment areas, including the neck bands. What matters more than the brand is the hand holding the syringe. A skilled injector like Dr. Hannah Berman, can help you achieve the results you are looking for.
| Product | FDA approved for | Since |
|---|---|---|
| Botox | Frown lines, crow’s feet, forehead lines, and the vertical neck bands | 2002 |
| Dysport | This one is for frown lines only, in adults under 65 | 2009 |
| Xeomin | Frown lines, crow’s feet, forehead lines | 2011, expanded 2024 |
Lanoi uses Botox. It is the only one approved for every area on this page, including the neck and jawline.
Just as important is who is injecting it. Dr. Berman places every injection herself.
Suitability
Who Is a Good Candidate for Botox?
Botox relaxes muscle. That makes it great for some lines and useless for others. Knowing which is which saves you money.
Botox Works Well If
| Situation | Why |
|---|---|
| The line appears when you move | Frown when you concentrate, squint in the sun, raise your brows when you talk. Those are muscle lines, and muscle is what Botox treats. |
| You are starting early | Treating a line while it is still dynamic stops it etching in. This is why people in their late twenties and thirties begin. |
| You are in good general health | Botox is low risk for healthy adults. Tell your provider about any neuromuscular condition. |
| You want subtle | Good Botox is dose-dependent. If you want movement preserved, say so, and it can be done. |
Something Else Suits You Better If
| Situation | What to consider |
|---|---|
| The line is there at rest | A crease visible with your face completely still is etched into the skin. Filler, laser resurfacing or both will do more. |
| You have lost volume | Hollow cheeks and deep folds are a volume problem. Relaxing a muscle does nothing for them. The injectables page covers fillers. |
| Your concern is texture or color | Sun damage, pigment and fine crepey skin are a resurfacing conversation. |
| You are pregnant or breastfeeding | Botox is not used in either case. It keeps, and so does the appointment. |
| You have a neuromuscular condition | Conditions such as myasthenia gravis need a proper discussion before any injection. |
Your Appointment
What to Expect During Botox Treatment
There is no preparation, no downtime and no recovery. Most people come in on a lunch break.
Duration
How Long Does Botox Last?
Three to four months for most people, with a predictable arc in between.
| When | What is happening |
|---|---|
| Days 1 to 2 | Nothing visible yet. The protein is binding at the nerve endings. |
| Days 3 to 7 | Movement starts to soften. Lines look shallower. Sides often settle at different speeds, which is normal. |
| Day 14 | Full effect. This is the day to judge the result, and the day Dr. Berman reviews you. |
| Months 1 to 3 | The result holds steady. Most people forget they had it done. |
| Months 3 to 4 | Movement gradually returns. Book before it fully wears off to keep the muscle trained and to receive your discount. |
Strong muscles, hard exercise and a fast metabolism can shorten it. Men often burn through it faster and need more units to start with.
Results often last longer after a year or two of regular treatment. A muscle that keeps getting relaxed stops working so hard.
Aftercare
Botox Before and After Care
A short list, and most of it is about avoiding a bruise.
| When | What to do |
|---|---|
| A week before | If you take fish oil, vitamin E, ibuprofen or aspirin and your doctor says you can pause them, do. They thin the blood and raise the chance of a bruise. Never stop a prescribed blood thinner without asking. |
| The day before | Go easy on alcohol, for the same reason. |
| On the day | Come with a clean face if you can. Makeup is fine, it just gets removed. |
| First four hours | Stay upright and leave the treated areas alone. No rubbing, no facials, no lying face down. |
| First 24 hours | Skip the gym, the sauna and the hot yoga. Ordinary walking is fine. |
| Days three to seven | You start seeing it work. Do not judge it yet, and do not panic if one side moves more than the other. |
| Day fourteen | Full result, and your review appointment. This is the day to say what you think. |
Choosing a qualified injector
Why Choose a Dermatologist for Botox
Choosing a qualified injector is one of the most important steps for safe, natural looking Botox results. Precise placement depends on a strong understanding of facial anatomy, muscle movement, and how each area of the face works together.
The bottom line is simple: the product itself does not change from one office to another. What changes is the judgment, training, and experience behind the needle. In California, injectables may be administered by licensed medical professionals who are not physicians, so it is important to understand who is performing your treatment and what level of training they have.
