The 36-year-old Brazilian beauty is raising her standards when it comes to her career.

Victoria's Secret Angel Adriana Lima is appearing to put her foot down when it comes to disrobing.

The longtime supermodel, who walked her 18th Victoria's Secret Fashion Show in November, spoke out on Saturday regarding her new stance on stripping down.

"I had received a call for the possibility of filming a sexy video of me to be posted and shared in social media," Lima, 36, wrote on Instagram. "Even though I have done many of this type, something had changed in me, when a friend approached me to share that she was unhappy with her body."

The Brazilian bombshell has posed for racy -- and even naked -- photo shoots for magazines in the past, but she now says that she is ready to "make that change."

"Everyday in my life, I wake up thinking, how do I look? Was I going to be accepted in my job?" she asked. "And in that moment I realized [the] majority of [women] probably wake up every morning trying to fit in a stereotype that society/social media/fashion etc. imposed. I thought that’s not a way of living and beyond that, [it's] not physically and mentally healthy, so I decided to make that change. I will not take [off] my clothes anymore for [an] empty cause. #Embraceyourself #naturalissexy #LOVEYOU" Adding that she wants to serve as a support system for anyone struggling, Lima also admitted that she, too, falls victim to her own personal insecurities. "I want to support you. I want you to know that I am here. I want to help if you allow me, to make you feel better," she wrote. "I have my own things/insecurities too, I am not afraid anymore to express them. They are part of me." Lima then addressed her modeling career with Victoria's Secret and stated that her job puts on "such big pressure to look a certain way," and she hopes to change that. "My job puts me in such big pressure to look a certain way. I was thinking, how can we [women] have to carry so much?" she said. "I am tired of the impositions, we 'as [women]' can't be continuing living in a world with such superficial values. It's physically and mentally not healthy what society is imposing us to be, to behave, to look… I want to change it, [in] the name of my grandma, my mother, and all her ancestors that have been labeled, pressured, misunderstood. And has to live according to Society. I will make that change. I will start with me." The longtime model concluded by resolving to "f**king change the world" on behalf of her daughters, 7-year-old Valentina and 5-year-old Sienna. - Frazer Harrison/Getty Images for Victoria's Secret

This isn't the first time Lima challenged the darker side of the fashion industry. In September, the new host of Lifetime's American Beauty Star, confessed that she prefers to embrace the more "positive messages in fashion."

"I think that the industry's changed," she told ET. "Everyone wants to feel connected with the person behind the makeup or whatever, the picture. People want to see that human connection… [for] my children, I think there’s a lot of positive messages in fashion and in beauty, and those messages are the ones I will embrace and I will reinforce into my children’s lives."

The fashion model added that she feels the most herself when she is speaking honestly about her emotions.

"I feel the most beautiful when I’m myself, expressing my feelings," she stated. "If I put on a red lipstick, because I love a red lipstick just because, I don’t have an explanation for that. That’s when I feel beautiful. If I don’t want to use anything, I don’t want to use anything."
