Medi-spas are proliferating, performing minimally invasive cosmetic procedures such as Botox injections, facial peels and laser resurfacing, and some are offering surgical procedures such as breast augmentation, abdominoplasty and blepharoplasty.

Some states have started to implement tighter regulations on the facilities, such as licensing and truth-in-advertising requirements.
