Stress has been proven to rid your body of many essential vitamins and minerals. Particularly vitamins C, E, and B. This leads to lethargy, lower focussed mental activities (clinically stress causes more erratic brain activity and a reduction in short term and long term memory), drying out and aging of the skin (in some), and in others a increase in the sebaceous gland activity - which usually brings postules, acne, and rosacea - which all bring more stress as we then become more entangled in how others view our physical appearance.
We cannot stop all stress, but we can take steps to stop or limit its toll on our skin and body. Take a full vitamin suplament every day. Eat a well balanced diet - especially fish meat like salmon (high in omega 3's which is proven to increase brain function and cellular activity, but it also is proven to reduce the aging process of the skin and make cuts and bruises heal faster). Eat more raw fruits and vegetables - atleast 5 servings per day - you will see a notable difference in 4-6 weeks and you will feel better (along with better colon health.
Exercise more often. Aerobic exercise has been proven to release powerful hormones that actually counteract the harmful chemicals and results of stress as it will also improve your bodys abilities to cope with oxidants.
I can't say enough about meditation and prayer. Study after study have proven a reduction in every skin and body malody even cancer symptoms from people that pray and meditate daily. Take 20 minutes every day and do this you will also live longer.
The latest rage is skin peels for a quick fix. Skin peels will slough off the top layers of skin and reveal fresher, cleaner skin. The most effective are TCA peels and phenol peels (phenol peels are dangerous and should only be performed by a licensed plastic surgeon). TCA, trichloroacetic acid, is a medium depth skin peel that works on the most skin ailments - aging skin, sun damage, even has been proven to treat and cure acne. No other skin peel can safely do all that a TCA peel can.
