What is a significant factor contributing to adult acne development?

High levels of stress are a significant factor contributing to the development of adult acne due to the complex relationship between stress and the body’s hormonal balance. When an individual experiences stress, the body produces higher levels of hormones such as cortisol. This hormone can lead to increased oil production in the skin, contributing to clogged pores and acne formation. Additionally, stress can exacerbate inflammation and disrupt overall skin health, making existing conditions worse.

In contrast, while exposure to sunlight can affect the skin in various ways, it does not have a direct, significant impact on the development of acne. Diets rich in refined sugars can influence acne by causing insulin spikes that may increase oil production, but it is not as universally impactful as stress. Excessive hydration, on the other hand, is generally beneficial for skin health and does not typically contribute to acne. Therefore, the connection between stress and hormonal changes is a key reason why it is seen as a significant factor in adult acne development.
