What precautions should be taken before and after Botox injections for facial slimming?

As living standards continue to improve, many individuals neglect dietary habits and frequently overeat, leading to excessive fat accumulation in the body. So, what precautions should be taken before and after receiving Botox injections for facial slimming?

Precautions to Observe Before and After Botox Facial Slimming Injections

After receiving Botox injections for facial slimming, avoid contact with water for a short period and refrain from consuming spicy or irritating foods. Promptly adjusting your routine helps facilitate rapid absorption of the medication. Specifically, avoid getting water on your face for at least 12 hours post-injection. If water accidentally contacts the treated area, immediately pat dry with a clean, dry towel. Additionally, avoid eating for 12 hours following the injection, as the Botox primarily targets the masseter muscles (jaw muscles). Any jaw movement—including chewing—within this timeframe may interfere with optimal drug absorption; therefore, it is advisable to eat beforehand.

Patients should avoid cold or hot compresses—and especially massage—in the immediate post-injection period. These activities may cause the injected botulinum toxin to diffuse into adjacent muscles. If the toxin spreads to the facial expression muscles, they too may atrophy, resulting in impaired facial expressions.

Fourthly, minimize excessive use of the masseter muscles after injection—i.e., avoid chewing very hard or tough foods. Overuse during the active phase of the toxin may lead to compensatory hypertrophy of the masseter muscles once the effect wears off, thereby diminishing or negating the facial-slimming results.

The effects of facial-slimming Botox injections typically last approximately six months to one year. Once the masseter muscles gradually enlarge again, repeat injections are required to maintain the slimming effect. Generally, after three to four treatment sessions, results become relatively stable.
