What is Excessive Caffeine?

Diuretic effects cause dehydration, and elevated cortisol can trigger breakouts

Consuming more than 400mg daily (about 4 cups of coffee) disrupts sleep and raises cortisol, impairing skin regeneration.

Main causes & characteristics of Excessive Caffeine

Caffeine is known to increase fluid excretion through its diuretic effect, potentially contributing to skin dryness. Excessive intake is also cited as potentially raising cortisol (the stress hormone) levels, which may encourage increased sebum production and breakouts. Consuming caffeine late in the day may disrupt sleep and interfere with the skin's nighttime regeneration cycle.

Managing Excessive Caffeine

Keeping daily caffeine intake to approximately 400 mg (roughly four cups of coffee) and tapering off in the late afternoon is generally recommended. Developing the habit of drinking water alongside coffee to replenish fluids may be helpful. If palpitations or sleep disturbances persist, or if skin breakouts recur, reviewing caffeine intake and consulting a specialist is recommended.

Related information

Caffeine is frequently discussed in connection with cortisol, diuretic effects, sleep quality, and stress. Caffeinated energy drinks, teas, and chocolate are also mentioned in the same context.

Everyday care tips

Caffeine can be hidden in energy drinks and desserts, and the cumulative amount may be surprisingly high. Switching to decaffeinated options or herbal teas in the afternoon is a useful strategy.
