Hi
I am not sure how severe your acne is. If it is severe, you should consult your doctor, who would be the best person to prescribe something to help you. ProActiv has alot of harsh ingredients in it, so I wont recommend it personally.
I notice that you live in Antigua, so obviously, your skin is exposed to alot of sunshine and hot weather.
Your skin may hyper-pigmentate when the spots heal (leave dark marks) because of the sunny weather. To try and avoid this, use a sunscreen at least twice daily to protect your skin.
As Babs said above, exfoliate weekly, but with a gentle product, not the abrasive ones.
Just be very careful with your diet. Try to eat loads of salads, fruits and vegetables. Eat oily or fried food in moderation. As Babs said above, drink loads of water.
Goodluck, and hope your skin clears up.
