A few tips;
Sleep - Get yourself as much sleep as your body needs. Only you know how many hours that is.
Washing - Don't use any shit on your face. No creams or soaps or nothing. Just use warm water and gently splash/rub for a few seconds.
Moisturiser - Use Vaseline after showers and when you wake up in the morning if you have dry skin.
Shaving - Use a good quality electric shaver.
Lip balm - Try not to use it. Gradually use less and less and put up with dry lips until they heal themselves back to somewhat normality. Do not lick your lips.
Excercise - Is great for the skin. Cycle early in the morning for a few minutes.
Sun - Get lots of fresh air and sunlight on your skin.
Water - Drink a few pints a day to keep hydrated.
Supplements - Iron and 2x Omega 3 per day.
Fruit - Eat it. Especially apples.
Junk food - Eat and drink whatever you enjoy.
Skin products - Fuck them.
