Here are a few random statements of advice:
St Ives Apricot Scrub is wonderful.
Sunlight is great for drying up spots. Sunbeds are good also (but they're not healthy).
The pill can help spots or cause them. If you're female and suffer from spots, consider starting/changing pills.
If you pump your body with crap, you'll look crap.
Saunas/steam rooms are good but you have to make sure you get the dirt out of your pores, then wash with cold water to close them up.
Don't pick spots. Spots last a week, scars last forever. Plus it's gross.
Greasy skin? You can get blotting paper for skin from Superdrug.
