Objective: To build a scientific content profile with validity evidence on the Instagram social network, focusing on health promotion for Brazilian and Portuguese university students regarding self-perception and self-image. Methods: . A multi-method study based on Design Thinking in four stages: Knowledge Building (1st Review with 26 studies and Documentary Study with 962 forms); Product Definition (2nd Review with 50 studies and Focus Group with 13 participants); Development (Profile Prototyping); and Evaluation and Delivery (with evidence of usefulness, ease, and acceptability assessed by seven users). Results: It was evidenced in 42.3% of the studies that young people have difficulties with the use of alcohol and drugs; among technologies for intervention, multimedia campaigns and social networks were highlighted. The majority (53.8%) of the records expressed the young people's desire to change something about their bodies. The focus group understood the need to intervene in the self-perception and self-image of young people through Instagram. The profile @multi.brasilportugal was created with content about the promotion of self-care, links for theoretical depth, and professional referrals. Regarding usefulness, ease, and acceptability, users considered it extremely likely to be useful for achieving the objective, extremely easy to operate the profile, and quite likely in terms of the clarity and understanding of the interaction with the technology. Conclusion: Design Thinking encouraged the creation of an Instagram profile with interaction and the possibility of using scientific content for education and health promotion, especially to improve body positivity and self-esteem.
