Causes and treatment of acne scars

Causes and treatment of acne scars – Acne lesions can cause scarring. Acne scars appear in the area where there cystic blemishes formerly appeared. People With inflammatory acne are at higher risk of scars after their acne has cleared. Picking or squeezing acne can worsen inflammation increasing the risk of scarring. If you have a blood relative who had acne scars, you are at more risk of developing the condition.

Causes of acne scars

When a breakout of acne penetrates deeply into the skin, they damage the skin and the beneath tissues.  When the acne begins to clear, the body attempts to repair the damage that had been caused. As the healing process continues, collagen is produced to offer support to the skin. If too much or too little collagen is produced, scars will appear. These may be raised or depressed scars depending on the amount of collagen produced by the body. Depressed scars occur when the body produces very little collagen. Pits or depressions form as the skin continues to heal. As the body tries to heal the skin and underlying tissues, it can produce too much collagen  which cause raised acne scars.

Factors that worsen acne scars


Exposure to the sun can cause the acne scars to darken and also slow the healing process. This is due to the fact that ultraviolet rays, the pigment-producing cells known as melanocytes cause discoloration. Before going outdoors, it is important to apply a sunscreen with an SPF of above 30 and containing zinc oxide. You should reapply after sweating, swimming or after every 2 hours in the sun.

Picking and squeezing

However, latest studies suggest that applying the nutrient onto the scar can prevent its healing. In fact the studies suggest that when applied directly, vitamin E has no effect or worsen the condition. The studies noted that a third of the people who applied the vitamin developed contact dermatitis.

Vitamin C is also an important ingredient to look for in OTC products.
