👉 The "pimple assumption" in psychology refers to the common belief that pimples are primarily caused by hormonal fluctuations, specifically increased androgen levels during puberty, menstruation, or pregnancy. This assumption overlooks other significant factors such as genetics, diet, stress, and environmental influences. While hormonal changes can contribute to acne, they are not the sole cause, and many individuals experience pimples without any obvious hormonal triggers. This oversimplification can lead to misunderstandings about acne treatment and prevention, emphasizing the need for a more holistic approach that considers multiple contributing factors.
