"So excited to support her as a skilled beauty technician opening her own Latina owned business!
"Here I am getting some Mono-Threads. Ayyyy Dios! I'll update you with results if you care."
However, the response from fans was mixed. Some left horrified comments while others shared their positive experiences with the treatment.
"Which movie of Saw was this on?" wrote one fan.
"The threads are a game changer! I work at a medspa and we see some incredible results!" commented another.
Surprisingly, the treatment is actually painless as local anaesthetic is applied to numb the area.
Using dissolving suture material, the threads are inserted into the skin to lift, tighten and rejuvenate the skin, making it a popular treatment for areas like the chin, neck, jowls, eyebrows and crow's-feet.
Although the procedure – also known as a non-surgical thread lift – originated in Korea, it's now much more mainstream and is available in the USA, UK and Australia too.
According to Sydney skin clinic, Allure Skincare, the results are most notable eight to 12 weeks after the treatment and last up to two years. The sutures get reabsorbed into the body after six to eight months.
This isn't the first time the mum-of-two and McHappy Day Ambassador has shared her love for the Beauty Villa Vergara clinic. In July this year Mendes uploaded an Instagram video which showed her receiving a facial using a Golden 'roller' Wand.
"Since I can't see her as much as I'd like to during these times, her affordable beauty tool is helping me fight gravity a little bit. (Don't tell this to my face but I think gravity has the lead)," she wrote.
Surprisingly the Gold Wand was only US$20 via Dr Vergara's website and claims to be able to help reduce the appearance of dark circles, help prevent wrinkles and lift skin.
