Acne Vulgaris
Acne Vulgaris ( 39 Questions)
Bacterial infection - This is incorrect because while bacteria can contribute to the inflammation seen in acne, it is not the primary cause. Acne develops due to the abnormal process of keratinization of hair follicles and increased sebum production.
The primary cause of acne vulgaris is hormonal imbalances, specifically an increase in androgen hormones during puberty. Androgens stimulate the sebaceous glands to produce more sebum, which can clog the hair follicles and lead to the development of acne. While bacteria (Propionibacterium acnes) can contribute to inflammation in acne lesions, it is not the primary cause of acne.
Excessive sun exposure - This is incorrect because while excessive sun exposure can exacerbate some skin conditions, it is not the primary cause of acne vulgaris. In fact, mild sun exposure can sometimes improve acne temporarily, but excessive sun exposure can lead to other skin issues and should be avoided.
Allergic reactions to skincare products - This is incorrect because while allergic reactions to skincare products can cause skin irritation, redness, and rashes, it is not the primary cause of acne vulgaris. Acne develops due to hormonal factors and other underlying mechanisms in the skin.
