Acne — nearly everyone suffers from outbreaks of pimples at some point in life.Unlike rosacea ,whiteheads and blackheads are found in acne and can be removed by squeezing or extracting.It starts when greasy secretions from the skin’s sebaceous glands plug the tiny openings for hair follicles (plugged pores).
If the openings are large, the clogs take the form of blackheads: small, flat spots with centers darkened by exposure to air.If the openings stay small, the clogs take the form of whiteheads: small, closed, flesh-colored bumps. Both types of plugged pores can develop into swollen, tender inflammations or pimples or deeper lumps or nodules. Cysts associated with severe cases of acne (cystic acne) are firm swellings below the skin’s surface that become inflamed and sometimes infected.
Sometimes the follicle wall breaks under the pressure of this buildup.
When this happens, sebum leaks into nearby tissues and forms a pustule – this is called inflammatory acne.
This can create cysts. Ruptured cysts can leave temporary or permanent scars.
Non-inflammatory type of acne formation – acne (whiteheads, blackheads).Inflammation (papules, blisters and thick cyst) caused by the formation of the final pustules, cysts.
Rosacea is basically different than acne, although the two can coexist. It is also sometimes called “adult acne.”
Unlike common acne, rosacea is not primarily a plague of teenagers but occurs most often in adults (ages 30-50), especially in those with fair skin. Different than acne, there are usually no blackheads or whiteheads in rosacea. Furthermore, most teens eventually outgrow acne whereas patients with rosacea don’t generally outgrow it.
Rosacea consists mostly of small red bumps that are not “squeezable” or extractable like blackheads.
Squeezing a rosacea pimple usually causes a small amount of clear liquid to expel. People with rosacea tend to have a rosy or pink color to their skin as opposed to acne patients whose skin is usually less red.
1)Common acne in teenagers starts with an increase in hormone production
3)Excess sebum clogs the openings to hair follicles– especially those on the face, neck, chest, and back
3) Hot and humid climate
4)Stress and lack of sleep
5)Other factors such as: pregnancy, taking birth control pills, menstrual period, may also lead to hormonal changes.
The face is the most common location of acne. Here, there are 4 to 6 millimeter red (erythematous) pustules,
some with bridging scars and fistulous tract formation (connecting passages). Severe acne may have a profound psychological impact
and may cause scarring. Effective treatments are available for this type of acne.
