What is the ruling on using subliminal messages (with music or Quran) to change a physical characteristic, such as removing acne and improving skin, and is this considered altering Allah's creation?

Striving to remove skin pimples is a permissible form of treatment, and not an alteration of Allah's creation. As for relying on the subconscious method, it has no scientific or religious basis, and it is impermissible to do so. The claim that it changes eye color is incorrect and may be due to the influence of waswasah (whispers from Satan).
