Coriander is a rich source of many essential vitamins like folic acid, vitamin C, vitamin A and beta-carotene. Studies have shown that coriander leaves and seeds contain 30% of the daily recommended amount of vitamin C. Vitamin C is a powerful antioxidant that is essential for a healthy body and skin.
Another, more costly treatment for cystic acne is laser surgery. A dermatologist or doctor can use a laser that emits small amounts of light to treat cystic formations. Laser treatments prove successful in ridding the skin of cystic acne, but the solution often proves temporary.
The most common types of medicines that doctors use to treat acne include: 1  Benzoyl peroxide, such as Brevoxyl or Triaz. 2  Salicylic acid, such as Propa pH or Stridex. 3  Topical and oral antibiotics, such as clindamycin, doxycycline, erythromycin, and tetracycline.
