Dr. Marin offers Botox injection in San Diego.
Over 2.5 million patients received Botox injections in 2009 alone! It is the number one cosmetic treatment available and has changed the way we look at ourselves forever.

Botox injections (now termed onabotulinumtoxinA to distinguish it from other products) and Dysport (abobotulinumtoxinA) is derived from a purified botulism toxin. In small therapeutic doses, Botox and Dysport prevent the nerves from releasing the chemical that causes the muscles to contract. When placed selectively in the frown and brow muscles, this serves to soften and smooth the forehead, elevate the brows to improve the shape and slow the aging process related to muscle movement.

The FDA first approved this treatment in the late 1980s for its use by ophthalmologists to treat the muscles’ spasms around the eye. Since that time, several other therapeutic uses have been found, including the treatment of excessive muscle contraction, excessive sweating of the underarms and hands, migraines, and the in the cosmetic arena to treat frown lines between the eyes.

Here at our San Diego practice, we regularly use Botox to treat lines across the forehead and in the “crows feet” area, but this is “off label” – meaning that the FDA did not officially approve it for this purpose. Still, we have found it to be extremely successful in treating these areas as well. Dysport was first FDA approved and introduced to the cosmetic market in 2009 and functions much the same except for dosing differences.

How Do BOTOX Injections Work?

This treatment works by being absorbed into the nerve fibers after injection. Once this occurs, Botox is processed and eventually blocks the nerve from releasing the chemical (acetylcholine) that causes muscle contraction. This is a relatively slow process and is the reason for the several day delays before the treatment actually takes effect, and you see the smoothing of your brow.

Your Appointment

If you schedule an appointment, you will visit with Dr. Marin and discuss the areas of concern. If he determines that you are a good candidate for Botox, we can perform the treatment during that same visit.

The procedure is well tolerated and only takes a couple of minutes, depending upon the number of areas treated. The injection locations and how much is needed will be determined at your consultation and largely based upon your muscles’ position and strength. This varies from patient to patient.

There is usually no effect of Botox injection 15 minutes after the procedure, and make-up can be applied almost immediately. You will not notice any instant change in your appearance, as it takes normally from three to five days for the product to take effect. It is usually a gradual onset and imperceptible to those around you. We recommend not exercising for one to two days after the procedure as your only precaution.

Recovery & Side Effects

Botox should last anywhere from 4 – 6 months, providing you with a smoother forehead and frown lines, softened crows feet, and improved brow position.

However, in 4 months, you will begin to notice that some of the product is wearing off. As a result, there will be some muscle function and forehead movement. Thus, when a patient goes from completely smooth to minimal movement – it appears that the treatment has completely stopped working. In reality, perhaps only 10% of the product has gone, and you will continue to see more movement increasingly over the next two months. This is normal and expected.

Side effects related to this treatment are rare and frequently mild. The biggest complaint that we get from our patients is that it is not a permanent change. I find this can be beneficial because if you don’t like the outcome, it will gradually disappear and not make any changes to your long-term appearance.

Side effects – though infrequent – are headache, incomplete correction, asymmetry, and brow droop. The more severe complications have never been seen in cosmetic doses and only in patients who suffer from muscular contractions of the neck and upper extremities.

When Do I Come Back?

There is no set time for your next appointment, but we commonly recommend to return 4 – 6 months from your last appointment. Normally, this is when muscle movement is returning, and the cosmetic benefit of the treatment is less apparent. However, there is no problem with waiting until your schedule permits.

Unanticipated Benefits

When we age, the lines on our faces are generated by time, exposure to the sun and other elements, and also our own muscle movement. Each time our muscles move, they cause the overlying skin to crease. After thousands and thousands of contractions, the skin will gradually weaken and thin leaving you with a crease not only when you are moving your muscles but even while at rest – meaning when you ARE NOT moving your muscles. These are much more challenging to address, and additional treatment will fix the movement problem, but not the “new” lines you have at rest.

Thus, if you begin to use botox before these lines develop, you can prevent or slow the onset of these unwanted lines at rest. If you can’t move your muscles, the skin will be less frequently creased, and thus these lines take longer to appear. You will be able to preserve your youthful beauty while obtaining the simultaneous immediate benefit of a smooth forehead and attractive, elevated brows. A two-fold benefit!

All non-acute follow up appointments, fillers and Botox will need to be postponed until after the quarantine period mid April. Our office will reach out to all patients who need to be rescheduled.
