Although acne is no longer seen as primarily a teenager problem, it does help to understand the underlying source of the issue. Janel Luu, CEO of Le Mieux Cosmetics and PurErb, explains some of the causes behind acne in teenagers and adults: 

  • For young adults, acne can be triggered by hormones, heredity, and follicle issues. Dry, dead skin congests and blocks the hair follicles. The situation is aggravated by an overproduction of sebum, resulting in microcomedones that lead to closed comedones or inflammatory lesions, which are the breeding ground for bacteria such as P. acnes. 
  • For adults, stress and lifestyle also tend to be a big component as well as hormones from pregnancy and premenopause. Some believe that acne can be food-related, but more scientific evidence is needed. Acne is understood as a skin disease, but from my observation, a lot of it also has to do with topical products that are congesting the skin. 
  • For estheticians and their clients, the key is understanding the hormonal aspect, and the topical application of products that cause acne. Plus, overwashing and over-exfoliating can lead to dryness, which can worsen acne. For men, beards or mustaches can aggravate acneic conditions.
