Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. Acne Treatment is very common in Teenagers.
It often causes whiteheads, blackheads or pimples, and usually appears on the face, forehead, chest, upper back and shoulders. Acneis most common among teenagers, though it affects people of all ages.
Signs and symptoms of Acne
Typical features of acne include increased secretion of oily sebum by the skin, microcomedones, comedones, papules, nodules (large papules), pustules, and often results in scarring. The appearance of acne varies with skin color. It may result in psychological and social problems.
Acne Scars
Acne scars are caused by inflammation within the dermis and are estimated to affect 95% of people with acne vulgaris.
Abnormal healing and dermal inflammation create the scar. Scarring is most likely to take place with severe acne but may occur with any form of acne vulgaris.
Acne scars are classified based on whether the abnormal healing response following dermal inflammation leads to excess collagen deposition or loss at the site of the acne lesion. Acne Treatment is important as it affects the mindset of other people too.
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). Ice-pick scars, boxcar scars, and rolling scars are subtypes of atrophic acne scars.
Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5–4 mm across. Ice-pick scars are narrow (less than 2 mm across), deep scars that extend into the dermis.
Rolling scars are broader than ice-pick and boxcar scars (4–5 mm across) and have a wave-like pattern of depth in the skin.
Hypertrophic scars are uncommon and are characterized by increased collagen content after the abnormal healing response.
They are described as firm and raised from the skin. Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders. Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.
Pigmentation
Postinflammatory hyperpigmentation (PIH) is usually the result of nodular acne lesions. These lesions often leave behind an inflamed darkened mark after the original acne lesion has resolved.
This inflammation stimulates specialized pigment-producing skin cells (known as melanocytes) to produce more melanin pigment, which leads to the skin’s darkened appearance. People with darker skin color are more frequently affected by this condition.
Pigmented scar is a common term used for PIH, but is misleading as it suggests the color change is permanent. Often, PIH can be prevented by avoiding any aggravation of the nodule and can fade with time. However, untreated PIH can last for months, years, or even be permanent if deeper layers of skin are affected. Even minimal skin exposure to the sun’s ultraviolet rays can sustain hyperpigmentation. Daily use of SPF 15 or higher sunscreen can minimize such a risk.
Scar
Acne or pimples, especially when longstanding or untreated may leave marks behind on the skin that are called acne scars. Acne treatment is important to get your skin cleaned up.
These scars are pitted and commonly have a wave-like appearance.
These are narrow but deep scars that give an impression as if a sharp object has pierced the skin. They develop after a deeply inflamed cystic acne lesion has spread to the skin surface. It is associated with the destruction or shrinkage of the skin tissue and hence, it is also called an atrophic scar.
