| This subtype resembles acne vulgaris, but with the absence of comedones. |
| Retinoids, which are derivatives of vitamin A, function by slowing the desquamation process, thereby decreasing the number of comedones and microcomedones. |

| Erythematous papules and pustules characterize inflammatory acne, but comedones may also be present. |
| These result from the action of the Vitamin A Acid on deep and previously unseen comedones and papules. |
