Just be sure not to exceed the recommended daily dosage, as it can be toxic. Any new skin
regimen you try should be given at least six weeks, especially given the severity of your acne.
A mild cleanser (such as Neutrogena's grapefruit acne wash), a alcohol-free toner (such as Boots, Neutrogena, or the Body Shop), and a quality facial moisturizer (such as Boots, the Body Shop, Olay, Aveeno) should be used day and night. Rinse your face with cold water to reduce redness and inflammation.
