Atrophic acne scars have lost collagen from the healing response and are the most common type of acne scar (account for approximately 75% of all acne scars).[31][32] They may be further classified as ice-pick scars, boxcar scars, and rolling scars.[30] Ice-pick scars are narrow (less than 2 mm across), deep scars that extend into the dermis.[31] Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5–4 mm across.[31] Rolling scars are wider than icepick and boxcar scars (4–5 mm across) and have a wave-like pattern of depth in the skin.[31]

Accutane is especially good for cystic acne in women and body acne in men. “Oral vitamin A basically shuts down your sebaceous glands. If you suppress [them] for a long enough period, you can cure someone of their acne, and about 50 percent do hit that cure rate,” says Linkner. A course of Accutane can take about six to nine months. Sometimes patients need to repeat the course at a higher dosage in order to truly eliminate acne.

If even a trace of sodium lauryl sulfate is left on the skin for more than an hour, however, the upper layer of living skin cells is irritated and dies. Tiny flakes of skin make the texture of the skin look uneven, and they can clog pores. The scent of sodium lauryl sulfate also causes your nose and tongue to be less sensitive to sweet tastes and their associated odors, so you will crave sugar.
Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment.[30][177] Until the 1930s, it was largely seen as a trivial problem among middle-class girls – a trivial problem, because, unlike smallpox and tuberculosis, no one died from it, and a feminine problem, because boys were much less likely to seek medical assistance for it.[165] During the Great Depression, dermatologists discovered that young men with acne had difficulty obtaining jobs, and during World War II, some soldiers in tropical climates developed such severe and widespread tropical acne on their bodies that they were declared medically unfit for duty.[165]
If you take a close look at the acne-fighting ingredients, you will find that no single ingredient does all the work to get rid of acne. Each one has a unique effect that plays a role in the elimination of acne, but only when they are used combined or in sequence in a system do they have ability to get rid of acne altogether. This is why it is so important to use an effective system for fight acne, not just a single product.

Although immediate results would be great, acne treatment does not occur overnight. It is a process that requires follow-up appointments to determine and adjust your treatments to your particular skin type. Expect six to 12 weeks for results. While waiting for an acne treatment to work, it can be tempting to squeeze lesions to get rid of them. Dermatologists do not recommend this. Picking, scratching, popping and squeezing tend to make the lesions worse and can cause acne scars.
Acne appears when a pore in our skin clogs. This clog begins with dead skin cells. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.
