Comediennes (primary acne lesions) are not initially swollen but with the passage of time do so because of the bacteria that live and pore blockage.

The signs of this inflammation are:

Pain
Blush
Abnormal color

However, other factors can trigger acne, such as heredity, hormonal imbalances and abnormal keratinization. In the latter case the generative material becomes dense and creates a cluster of cells that clog the follicular canal and sebum pilot the entire unit.

Emotional factors also influence the appearance of acne, nerves releases testosterone in both men and women, and this hormone predisposes to the problem. Moreover, hormonal drugs and corticosteroids as occupational external agents (tar, mineral oils, hydrocarbons, …) are also cause of acne at any age.
Acne produces various types of injuries, including:

Seborrheic: the excess sebum in the pore outlet shows its very dilated.

Comedogenic, are non-inflammatory lesions. The comedones may be open (commonly called blackheads) or closed (or yellowish white spots and difficult to see under the skin).

The bumps are the inflammatory response to comedones, following them is that they produce pustules (pus-filled arise once broke pilosebaceous gland), painful and have pruritus.
Clinical variants of acne

Not all acne is the same, within the disease there are several classifications that are based on the causes and severity.

Acne microquísitico: greater number of closed comedones and usually occurs in women during the second decade of life. Treatment has a very difficult and can be caused by cosmetics .

Excoriated acne, predominantly women, begins as a mild acne and being subjected to constant handling sectors are generated inflammation, erosions and crusts on the face. (This is when they break the grains).

Like many acne treatments, acne creams are usually more effective when used daily. You will find that usually come in one of two ways, either natural of all the creams and medicated creams. Everything depends on the person to decide what is best for them, however some people respond better to creams that contain only natural ingredients (and do not include chemicals that many people have adverse reactions). On the other hand, some people get much better results from the extra punch that comes with a medicated cream.

Unfortunately, the only way to tell which is the best choice for you is to try out for yourself. Like most acne resources, we all have different reactions to different types of treatment, so a little trial and error may be needed to reduce the types of acne creams work best for you. Of course, if you have had good or bad results with other natural or medicated acne treatments, which should help guide in the right direction.

Regardless of what type of acne cream you choose, you should exercise caution when using it. Whether or not medicated, could still cause an adverse reaction if used incorrectly, so be sure to follow the directions on the label. The last thing we want is for your cream for acne that is worse because they are used incorrectly.

Acne creams are one of a number of ways to remedy acne outbreaks. If you have not tried an acne cream (or not used at a time), it might be time to give this treatment a shot and hopefully enjoy clear, smooth skin as a result.
