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.

Characteristics & nutrition facts

Caffeine is known to increase fluid excretion through its diuretic effect, which may contribute to skin dryness. Excessive intake is also cited as potentially raising levels of the stress hormone cortisol, which may promote sebum secretion and breakouts. Consumption late in the day may disrupt sleep and affect the skin's overnight regeneration rhythm.

How to manage

It is generally recommended to limit daily caffeine intake to approximately 400 mg (about 4 cups of coffee) and to reduce intake in the late afternoon and evening. Developing a habit of drinking water alongside coffee to replenish fluids may be helpful. If palpitations or sleep disturbances persist, or if skin breakouts recur, reviewing intake and consulting a specialist is recommended.

Good to know alongside

Caffeine is frequently discussed alongside cortisol, diuretic effects, sleep quality, and stress. Caffeinated energy drinks, tea, and chocolate are also mentioned in this context.

Everyday care tips

Caffeine can be hidden in energy drinks and desserts, and the total amount may add up more than expected. Switching to decaffeinated beverages or herbal tea in the afternoon is a good option to try.
