» AMINOPHYLLINE
Aminophylline decreases the activity of enzymes that inhibit fat-burning within fat cells. Studies show that topical creams containing aminophylline can reduce fat levels directly beneath the skin. When combined with topical ingredients that increase fat-burning through different mechanisms, aminophylline has been shown to be even more effective at decreasing fat stores.
» FORSKOLIN
Forskolin
comes from the herb coleus forskohlii, a traditional Indian herb used in
Ayurvedic medicine. It also plays an important role in fat-burning within fat
cells. Oral forskolin supplements have been shown to reduce bodyfat while
boosting testosterone levels. Topical forskolin creams have also helped study subjects
lose subcutaneous fat when used consistently for four weeks.
» CAFFEINE
Caffeine is
probably the most clinically studied and most commonly used oral supplement for
fatburning. A study as far back as 1979 found that caffeine is also well
absorbed through the skin, as evidenced by increased urine levels of caffeine
after topical administration in humans. Because of caffeine's high permeation
through the skin, it's used medically in certain conditions for increasing
delivery of caffeine in the body. Topical caffeine applications also increase
blood flow -- important for burning fat since limited blood flow can be a limiting
factor in fat usage.
