There are two types of post acne marks: Acne scars and Brown Spots. Scars are a result of damage to the dermis. Brown Spots are a result of excess pigmentation. The rest of the article will focus on the treatment of the post acne brown spots, which is far more common than post acne scars.
Sometimes, after acne clears up, it leaves small, flat dark marks in place of where the pimples was. These marks are due to excess pigmentation that is a result of the inflammation induced by the acne. Pressing or squeezing pimples can also contribute inflammation which will worsen the post acne brown spots. People with darker skin types are particularly vulnerable to post acne brown spots.
There are 2 main treatment options for post acne brown spots:
1. Wear a sunblock on a daily basis. This will prevent the sun from further tanning and darkening the dark spots.
2. Apply a skin lightening cream to the brown spots once or twice a day. Effective skin lightening creams are prescription medication and include products like Hydroquinone and Retinoids.
Lightening the post acne brown spots can take weeks to months.
