What is a pitted scar?

Sẹo rỗ là gì?

Pitted scars, also known as indentations, are sequelae left by severe wounds on the skin, most of which are open wounds, with many causes such as acne, chickenpox, cosmetic allergies, trauma ... The skin structure of the injured area changes, especially the breakdown of collagen and elastin layers under the skin, causing the healing process to take place abnormally and forming concave scars.

What causes pitted scars?


  • Sequelae of acne (pustules, acne, inflammatory acne, other types of acne)

It is the main and most common cause of improper care and squeezing acne. When not equipped with basic knowledge about acne skin care, patients often pop pimples on their own, do not clean their hands or squeeze tools, do not know how to take care of acne, which easily causes inflammation. Infection, ulceration leads to necrosis and loss of tissue mass causes concave scars  (pitted scars).

  • Scars caused by skin diseases (chicken pox, chickenpox, folliculitis)

Similar to acne, skin diseases such as chickenpox (chickenpox) also cause obsessions for people because of its easy scarring sequelae. Scars caused by chickenpox (chickenpox) are very dangerous, can cause superficial scars from 3-8mm, very difficult to heal or treat.

  • Strong cleaning, trauma, burns or surgery

Regardless of skin type, when affected by scratches, it is very easy to lead to the risk of scarring. For small and new scars, you can use natural ingredients such as coconut oil, aloe vera, .. to treat or special creams for scars. As for long-term scars, large scars or infections, you should see a dermatologist for proper treatment.

  • Improper diet and direct exposure to sunlight

When there are open wounds, avoid eating fast food, greasy food, spinach, glutinous rice and seafood that will easily cause keloids and concave scars. In addition, being exposed to a lot of sunlight during an open wound will easily create conditions for ultraviolet rays to directly reach the damaged skin and cause rapid scarring.
