A team of scientists have said that minor cosmetic procedures are much after than earlier thought and people can undergo minor surgeries without facing much risk.

They claimed that minimally invasive cosmetic procedures including fillers, neurotoxins and laser and energy device procedures are much safer than believed. They said that these procedures ate safe and pose no risk of serious effects.

The study was conducted by the researchers from Northwestern Medicine. They tested more than 20,000 procedures across the US in the first ever study of this scale. It is the largest study involving multiple centers, where researchers studied the rate of adverse events by experienced dermatologists. These procedures are commonly used to decrease the signs of aging.

They said that side effects such as bruising, redness, swelling, bumpiness or skin darkening are temporary and heal without any treatment. They found that such minor effects occur only in 1 per cent of the patients. They studied 20,399 procedures performed by 23 board-certified dermatologists at eight centers over a period of nine months.

Murad Alam, M.D, who led the study said that people planning to undergo such procedures are not putting them at high risk. He said that people can benefit from small procedures instead of one large procedure. Small procedures can be mixed and matched to suit individual requirements.
