Acne treatment

Depending on the severity and persistence of the acne, the acne treatment for each level of acne will be different. 

Mild condition

Mild acne can be treated with over-the-counter medications that are taken by mouth or applied to the skin. These medicines usually contain the following active ingredients:

  • Resorcinol: Breaks down tiny blackheads and whiteheads.
  • Benzoyl peroxide: kills bacteria and accelerates the regeneration of new skin, slows down the secretion of sebum on the skin.
  • Salicylic Acid: Helps to overcome blackheads and whiteheads, and reduces inflammation in larger acne spots.
  • Retin-A: unclogs pores.
  • Azelaic Acid: prevents excessive sebum production, limiting the growth of bacteria.

Moderate to severe condition

For moderate to severe acne, your doctor will prescribe more severe acne medications or oral/topical antibiotics.

  • Oral antibiotics: Usually prescribed from about 1 month to 6 months at most. The goal of this drug is to reduce the growth of P.Acnes bacteria – one of the bacteria that live on the skin that causes acne. However, if antibiotics are used excessively, P.Acnes can become resistant strains and require stronger antibiotics. For the above reason, treating acne with antibiotics is often more of a topical antibiotic than an oral antibiotic. Some commonly used antibiotics are erythromycin and tetracycline.
Oral antibiotics
  • Birth control pills: Oral contraceptives are also a relatively common acne treatment, especially among women. The mechanism of action of oral contraceptives may control the development of acne in women by inhibiting overactive oil glands. This is a long-term remedy and prevention of acne, however, some women should not use birth control pills. In addition, to use this method long-term, you also need to have a gynecological examination with a doctor first.

  • Topical anti-infectives: Topical antibacterial drugs serve the same purpose as antibiotics: to reduce the growth of P.Acnes bacteria in patients with moderate to severe acne, most commonly clindamycin, sodium sulfacetamide. In addition, there are retinoids. Retinoids are a derivative of vitamin A with the purpose of unclogging pores, preventing the formation of whiteheads and blackheads. Some commonly used topical retinoids are adapalene, tazarotene, and tretinoin…

This is a potent oral retinoid that is often used as a treatment for severe acne that has not been responded to by other treatments. However, the use of this medicine can lead to:

Dry face, dry lips.


Unusual mood swings.

Laser resurfacing

  • Using laser resurfacing has become increasingly popular in recent years with very promising results. Among the lasers used, fractional CO2 is the most common. Fractional CO2 performs the scar regeneration process by sending a laser beam deep down to the structures below the concave scar, the heat generated from this laser beam will stimulate the fibroblast cells to produce collagen and elastin fibers. new, promote regeneration, heal acne scars.

  • The outstanding advantage of Fractional CO2 is that the laser beams act on the target tissue according to each energy column, ie, only where the laser affects the new laser will cause damage, and the surrounding areas are almost unaffected. . This advantage makes the CO2 laser increasingly popular because it shortens the recovery time after treatment, limits complications caused by the laser, and still ensures maximum effectiveness.
  • However, CO2 lasers in some cases can still cause post-inflammatory hyperpigmentation, causing prolonged redness. Therefore, it is necessary to perform this procedure in reputable facilities by dermatologists.

Needle roller

A classic method of scar treatment, it works by using microscopic needles that act repeatedly, causing small lesions in the skin. These lesions stimulate the production of growth factors, which promote healing and collagen production, which contribute to the filling of acne scars. The outstanding advantage of needle roller is to limit the damage to the epidermis layer, limit the risk of post-inflammatory hyperpigmentation. However, it takes time to see the results of dermabrasion, some studies suggest that it can take 8-12 months for the effects of dermabrasion to reach their maximum effect.

Separation of the bottom of the scar

Acne causes inflammation in the dermis of the skin. This inflammatory process entails the proliferation of collagen and elastin fibers, but these connective fibers are arranged in many different directions, intertwined, leading to the formation of bad, concave scars.

Basal cleavage is the use of a fine needle, inserted into the dermis of the skin, with the goal of severing these abnormal connective fibers. Facilitates the formation of new collagen and elastin fibers in a more orderly manner. This method is often used in conjunction with fractional CO2 or micro-needling


This method uses platelet-rich plasma extracted from the patient’s own blood. Platelet-rich plasma contains growth factors, which play an important role in stimulating collagen and elastin production from fibroblast cells. This is a safe method, often combined with fractional CO2 or micro-needling to increase the effectiveness of the treatment.


Super abrasive method

This method uses devices with abrasive tips embedded with quartz or diamond crystals, with the goal of removing the epidermis or possibly partially reaching the dermis of the skin. A few studies have shown an increase in collagen after microdermabrasion. However, this method is only suitable for certain types of scars, this method often causes pain, changes in skin color, the risk of scarring, as well as after treatment, the skin will become fragile, so it is easy to catch the sun and cause hyperpigmentation.

Chemical peels

The active ingredient used will cause damage to the skin, stimulating the production of collagen to help fill acne scars. This method is also only suitable for a few types of small concave scars. However, a worrying complication with the use of chemical peels is post-inflammatory hyperpigmentation, especially in Asian skin.

Chemical peels

Currently, there are many different methods used to improve the condition of acne. However, for each certain type of acne scar, there are appropriate treatments. Therefore, acne scars need to be carefully examined by a dermatologist, so that a safe treatment method can be selected and the best results can be obtained.
