Cortisol, known as the ‘stress hormone’, plays a crucial role in a number of physiological functions, but its prolonged presence at elevated levels can negatively impact skin health:
- Inflammation: Elevated cortisol levels can trigger inflammatory processes in the body. In the skin context, this translates into increased inflammation, which contributes to the development of conditions such as acne, psoriasis and dermatitis. Chronic inflammation can exacerbate these skin problems and negatively affect the appearance and health of the skin.
- Reduced collagen production: Excess cortisol can interfere with the production of collagen, a protein essential for skin elasticity and firmness. Decreased collagen synthesis can result in the formation of wrinkles and fine lines, contributing to premature skin ageing.
- Water retention problems: Cortisol can affect the skin barrier, compromising the skin’s ability to retain water. This dysfunction can lead to dehydration of the skin, making it more prone to dryness and sensitivity to environmental factors, which can worsen the skin’s appearance and health.
- Slowing the healing process: Elevated cortisol levels can interfere with the skin’s natural healing process. This interference can prolong the time it takes for wounds to heal, increasing the risk of permanent scarring and affecting the integrity of the skin.
- Increased sebum production: In some individuals, cortisol can stimulate the sebaceous glands, resulting in increased sebum production. This overproduction of sebum can contribute to the development of problems such as acne, as excess oil on the skin can clog pores and encourage bacterial growth.
- Loss of elasticity: Chronic exposure to cortisol can lead to loss of skin elasticity. Elasticity is essential for skin firmness and suppleness, and a decrease in elasticity can contribute to a more aged and sagging appearance of the skin.
It is essential to recognise individual variability in the skin’s response to cortisol and to adopt practices that promote stress management, such as regular practice of relaxing activities. In addition, proper skin care, taking probiotics to help counteract excess cortisol, a balanced diet and protection against environmental damage are essential to maintaining healthy, radiant skin.
