Acne is a common inflammatory skin disease that mainly affects the face, neck, chest and upper back. It is caused by an interaction between Hormones, bacteria and sebum produced by the sebaceous glands in the skin. Symptoms show as comedones (pimples), pustiles (lessions filled with pus) and occasionally Cysts. Acne is traditionally thought to developat Puberty but many women have acne throughtout life or it may develop in adulthood. It can develop premenstrually or may be associated with the talking or stoping of Oral Contraceptive Pills. This is possible caused by changing hormone levels.

Acne scarring is caused by a variety of factors. When acne is produced on the skin as a response to sebum, the body may attempt to target the inflammation with white blood cells. Once the inflammation has subsided, however, the tissue may have yet to be fully repaired, and as such, scar tissue will show. It is important, however, to note that marks on the skin are not necessarily scar; simple marks will usually disappear within seven months, though they may take up to two years to disappear completely.
Acne scar should not be confused with Post Inflammatory Hyperpigmentation.
Some people are more prone to acne scar than others. Acne scar should be treated early, with dermatological consultation, to reduce their visibility and size later in life. There are several forms of treatment for acne scar in current usage
2. Laser therapy (Fractional laser resurfacing)
3. Chemical therapy (Different kind of peels )
4. Biological treatment (enzyme, aroma, etc)
Skin is the largest organ of the body. It is made up of two layers, the upper 'epidermis' and the lower 'dermis'. The epidermis and the dermis are further divided into other layers.
The lower most layer of the epidermis is known as the basal layer and it contains organelles called 'melanosomes'. These melanosomes contain cells called melanocytes which produce a pigment called 'melanin'. The color of skin depends mainly on this melanin and the amount of melanin present in the other layers of the epidermis. The thickness of epidermis and vascularity of the epidermis are other factors affecting the color of skin.
What are the causes of hyper pigmentation (increase in skin pigmentation)?
1. Hyper pigmentation may either be due to increased melanin deposition in the epidermis or dermis.
2. Epidermal pigmentary disorders respond well to treatment while dermal pigmentation may take a long time to lighten.
3. Melasma: Seen as brown patches on the face, it is more commonly seen in females. It occurs due to hormonal changes in the body. The pigmentation increases on sun sun exposure.
4. Peri-orbital melanosis: Also known as 'dark circles' may be heriditary, due to stress or eye strain.
5. Freckles and Lentigenes: These are tiny black spots on the face and are genetic in origin.
6. Photomelanosis: This is increased pigmentation due to sun exposure. The pigmentation occurs on exposed skin, commonly on the face, neck and the back. The pigmentation may be patchy or as diffused darkening of the exposed skin.
7. Sun burn (tan): A condition commonly encountered in fair skinned people due to excessive sun exposure.
