Common side effects are bruising and swelling. Rarely, there is “serum sickness,” which manifests as flu-like symptoms that subside in a few hours, says Mulholland. “A dreaded complication is that the Botox travels through fatty tissues to muscles it wasn’t intended to block — like a muscle of the eyelid, which leads to ptosis (droopy eye), or the muscles that move the eyeball, leading to double vision.” He says these happen to less than one per cent of patients and go away within two weeks. The Botox Cosmetic website states asthma symptoms and inability to swallow have also been reported.
Deep chemical peels involve a longer procedure and longer recovery time that lasts up to several months in some cases. Patients who want to correct blotches caused by sun exposure or age, minimize coarse wrinkles, or remove a pre-cancerous growth may benefit from a deep peel. There are certain factors which must be taken into consideration when contemplating a deep chemical peel. Darker-skinned patients and individuals with heart problems are not ideal candidates. Potential chemical peel candidates should be aware that the treatment may take an hour or more, and may require sedation. Anyone who decides on this procedure should be prepared for a long, slow recovery period, and should wear sunscreen whenever exposed to sun.
