Acne A chronic disorder of the hair follicles and sebaceous (oil) glands. There is non-inflammatory acne classified as blackheads and whiteheads. Inflammatory acne is characterized red and inflamed papules, pustules, cysts and nodules. Scarring of the skin can result from these breakouts.

Acne Rosacea Acne-like appearance characterized by redness, sensitivity, irritation and flushing centralized on the middle of the face, particularly on the nose and across the cheeks.

Actinic Keratosis Small, rough reddish patches on the skin. Often sharp to the touch. Most common in fair-skinned people, these may become skin cancer if not removed.

Alcohol SD-40: sometimes listed as SD Alcohol 40 and synonymous with alcohol SDA-40, it is a high grade purified cosmetic alcohol.
