Adult-onset acne is a prevalent skin condition frequently observed in individuals over the age of 25, including those who did not experience acne during adolescence. Dermatological experts clarify that this condition affects both oily and dry skin types with equal frequency. While certain dietary components, such as sugar and dairy, can exacerbate existing breakouts, they are not identified as the fundamental cause of adult acne.
Dermatologists further explain that shifts in hormones or environmental factors are significant triggers for adult acne. They also caution against dismissing acne, even in teenagers, as a normal or benign aspect of development, emphasizing its commonality but not harmlessness.
