Minors usually cannot make their own independent decisions on whether to undergo cosmetic surgery. The main reasons are as follows: 1. Law and guardianship: The laws of most countries and regions stipulate that minors (usually those under the age of 18) need the consent of their legal guardians (such as parents or other guardians) for major decisions such as medical treatment and cosmetic surgery. Because minors are still in the stage of growth and cognitive development, the law believes that they may not have sufficient judgment to make such decisions independently. 2. Medical ethics and risk assessment: Cosmetic surgery belongs to the medical category, involving surgical risks, sequelae, psychological expectations and long-term effects on appearance. Doctors need to comprehensively evaluate the applicant's physical and psychological conditions and expectations for surgical results when providing advice and services. For minors, the effect of surgery may change as they grow, and their maturity and ability to cope with the consequences of surgery may also be insufficient, so they generally consider whether such surgery is appropriate more carefully. 3. Family and psychological factors: When minors make major decisions, family support and guidance are very important. Parents or guardians usually make comprehensive considerations based on their children's health status, psychological tolerance and future development. Therefore, in many cases, the decision on cosmetic surgery for minors is the result of a family discussion and the advice of professional doctors, rather than a unilateral decision made by the child alone. It should be noted that specific regulations and implementation details may vary by country, region, and medical institution. If you or a minor you know is interested in or concerned about cosmetic surgery, it is recommended to consult a professional medical institution, psychologist, and legal advisor to understand the specific applicable policies and possible risks. Please remember that all decisions involving medical beauty should be based on ensuring health and safety, while respecting the growth rhythm and psychological needs of minors.
