Stress and skin.

Cortisol, the central stress hormone, inhibits collagen formation, weakens the skin barrier and slows wound healing. Chronically raised levels measurably accelerate skin ageing – studies show thinner skin and more fine lines in people under constant stress.

Tension becomes a line: when tense, we frown, pull the brows together and clench the jaw. The frown line and a squared jaw from thickened chewing muscles are often stress markers more than signs of age. Teeth grinding (bruxism) increases markedly in demanding phases.

Acne and redness: stress raises sebum production via androgens and promotes inflammation. Flare-ups of acne, rosacea or eczema often coincide with exam or project phases.

Sleep and behaviour: stress shortens sleep, increases alcohol, sugar and nicotine intake and makes the skincare routine slip – four indirect ways it burdens the skin.

What helps: the cause cannot be treated aesthetically. But the visible consequences can be softened: botulinum toxin relaxes the frown line and the chewing muscle (also for bruxism), skin boosters strengthen dried-out skin. For persistent exhaustion, sleep disorders or low mood, the GP or psychotherapeutic counselling is the right path – not the needle.
