Acne vulgaris is a chronic skin condition caused by the overproduction of sebum, epidermal keratinisation disorders and the growth of Cutibacterium acnes, which can be aggravated by e.g. stress, sleep deprivation, unhealthy diet or stimulants. In addition to dermatological treatment and appropriate care, supplements such as omega-3 fatty acids, zinc, vitamin D and probiotics are supportive, which reduce inflammation, regulate sebum secretion and support the intestinal microbiota. It is always advisable to consult your doctor before choosing the right product.
