Stress causes a chemical response in your body that makes skin more sensitive and reactive. It can also make it harder for skin problems to heal.
Have you ever noticed that when you are stressed, you break out more? This is because stress causes your body to produce cortisol and other hormones, which tells your sebaceous glands to produce more oil. Oily skin is more prone to acne and other skin problems.
Stress can also:
Worsen skin problems. For example, stress can worsen psoriasis, rosacea, and eczema. Stress can also cause hives and other types of skin rashes and trigger a flare-up of fever blisters.
Interfere with daily skin care. If you are stressed, you might skimp on your skin care, which can aggravate skin problems.
Skin problems can also be stressful.  Some people are so embarrassed by their skin that they keep to themselves, which adds more stress, worsening the problem.
If you have a skin problem that doesn't heal or keeps coming back, rethink how you handle stress.
