Botox is widely known to be incredibly effective at reducing wrinkles and fine lines. Here's the thing, though: Injections aren't exactly cheap or a one-and-done procedure.

So before you invest in Botox, you may be doing some light math and asking yourself just how long the results last so that you can ensure you get your money's worth. We talk about injectibles a lot in our line of work, and what we hear constantly is that people want to know how to extend the time between treatments as long as possible.

We asked dermatologist Dr. Stacy Chimento to find out how long Botox lasts, how to prolong results, and how often you really need to go in for touch-ups.

What Is Botox?

"Botox is a drug that is formulated from a type of bacteria known as Clostridium botulinum," Dr. Chimento told us. 

The injectable works by stopping your muscles from receiving signals from nerves to inhibit movement, therefore eliminating wrinkles and fine lines that often form as a result of repetitive (think: squinting), according to Dr. Chimento.

The Benefits

Apart from reversing signs of aging, it's also worth noting that Botox isn't purely used for cosmetic purposes. Injections in a patient's underarm can decrease hyperhidrosis — or excessive sweating — and injections in the head and neck can help to relieve migraines, noted Dr. Chimento.

The Results

After injections, Dr. Chimento suggested it typically takes two weeks for the Botox to set in. Once it's completely set, results can last anywhere from three to six months, though she said most patients can expect it to last around four months.

Your next question might be, "Do I have to receive my next treatment right at the four-month mark?" The answer is it totally depends on your face, age, and the severity of the condition you're treating.

"I typically suggest that patients pay attention to where the Botox was administered and take note of when it begins to wear off," Dr. Chimento said before adding that she usually recommends patients come back around the three- to four-month mark.

How to Prolong Results

Apply Sunscreen Daily

Wearing SPF is important to stay protected against damaging UV rays and prolong your Botox results, too. According to Dr. Chimento, applying SPF can make the treatment last longer because UVA and UVB rays from the sun can "penetrate the skin and damage the longevity of your Botox treatment."

She advised to apply an SPF every morning and avoid long periods of sun exposure. Also, grab your shades on those sunny days because squinting excessively can cause the treatment to wear off quickly or even create more lines.

Invest in Anti-Pollution Skincare

Another thing that can damage the effects of Botox? Free radicals. Dr. Chimento suggested using an antioxidant serum to "neutralize free radicals" and protect your skin from pollution.

Look for Products with Skin "Plumping" Ingredients

If you're looking for more ways to maintain the treatments, Dr. Chimento recommended looking for products that contain collagen and peptides to "plump" the skin, as well as assist the Botox in working properly for longer periods. She likes the SkinCeuticals Triple Lipid Restore because it "contains different cellular lipids like ceramides and fatty acids to encourage natural cell reproduction."
