What is Botox?

Botox, medically known as botulinum toxin, is a neurotoxic protein produced by the bacterium Clostridium botulinum. Botox is used in both cosmetic capacities and medical. Botox is used to medically treat issues such as chronic migraines, muscle spasms, and hyperhidrosis, however, it is commonly used cosmetically as a muscle relaxer that temporarily reduces the appearance of facial wrinkles and fine lines. “Botox prevents the release of acetylcholine, a neurotransmitter that transmits signals for muscle contractions, thus making the surface skin appear smoother,” as explained by Dr Maria Johnson, a certified dermatologist, says.

Though the exact time period varies from individual to individual, Botox generally starts taking effect 24 to 72 hours after injection. The full results may not appear until 7-14 days later, as noted by Dr Peter Richards, a well-versed plastic surgeon. “Metabolism; quantity injected; area treated – these are some of the factors that can determine when Botox will become active,” he says citing clinical researches done on it. For example, about 50% of patients experience partial improvement within 3-4 days while the remaining half may take up to 2 weeks or more before they see maximum benefits according to him.

Why Are the Effects of Botox Not Immediate?

The effects of Botox are not immediate because the body needs time to get used to the acetylcholine effects. When injected into muscles, Botox blocks nerve signals that are responsible for muscle contraction. This takes time because the neurotoxin has to attach itself onto nerve endings and stop them from releasing any more neurotransmitters. Dr Angela Martin, a neurologist explains that “Binding of botulinum toxin with nerve terminals is a complex procedure which requires some period before achieving its full potential of muscle relaxation hence why immediate changes post-treatment are not visible to patients.”

What does Botox feel like when it starts to work?

What should you not do after Botox?

Aftercare plays a significant role in the success of your treatment and reducing the associated risks. You must remain upright and avoid strenuous activities for at least 4 hours after treatment. This will also prevent the spreading of the toxin to other unintended areas. For the first 24 hours, do not expose yourself to too much heat or sunlight neither should you massage the treated area so that you ensure that the Botox stays where it was injected. Dr Samuel Green says that one should follow through with these instructions because they will help them achieve maximum results out of their procedure and keep them safe as well.


It is important to have an idea about when the effects of Botox take place so that a a person can manage their expectations properly while ensuring that they get the best out of the treatment. The reason why visible changes might take longer than expected after injecting this neurotoxin lies in its mechanism; after binding with nerve endings, it needs time before inhibiting muscle contractions becomes noticeable. It is therefore crucial for individuals who have undergone or planning on having these injections done on them to stick by what experts say about post-treatment care lest anything goes wrong during or after such procedures. This means also consulting with qualified doctors before deciding anything related.
