Papules,
pustules, nodules and cysts are different types of acne lesions.
Acne severity can be classified into four "grades," depending
on the type of lesions present.
Grade
1: characterized by the presence of blackheads, whiteheads
and occasional pimples.
Grade
2: like Grade 1, but with more frequent pustules.
Grade
3: consists primarily of pimples, pustules and occasional
acne cysts.
Grade
4: the most severe form of acne, is typified by the presence
of acne cysts.
Non-prescription
products such as Stridex should only be used to remedy and prevent
mild to moderate (Grade 1 & 2) acne. For more severe cases,
a doctor should be consulted.
