Peace be upon you. According to Grand Ayatollah Sayyid Sistani (may Allah protect him), it is permissible as long as one avoids prohibited touching and looking, and it is necessary to cover it from non-mahrams if it attracts their attention. Grand Ayatollah Sayyid Khamenei (may Allah protect him) states that there is no issue in itself if it does not cause significant harm, but this procedure is not considered a treatment for diseases, so prohibited looking and touching are not allowed. If it is regarded as adornment or attracts attention leading to corruption, it must be concealed from non-mahrams, and the responsibility for determining this lies with the individual. May you be successful in all good.
