<h1>DNA-based skincare tests raise obligations for genetic data protection, informed consent, clinical claims, and liability risks under GDPR Article 9</h1> A dermatology-led medico-aesthetic clinic chain has launched a DNA-based skincare program using saliva microarray tests to analyse 130+ genes and 150 traits, offering personalised treatment plans. Legal considerations include genetic data privacy and consent obligations under applicable data protection and health privacy laws, potential need for specific informed consent for genomic testing, and secure storage/transfers of sensitive health data. Regulatory scrutiny may arise over medical device/diagnostic classification, clinical validity and efficacy claims, and advertising standards for health claims; liability risks include malpractice, data breaches, and consumer protection enforcement if claims are misleading.
