Acne: Scars and hyperpigmentation

Skin inflammation in acne can cause scarring and over pigmentation (hyperpigmentation). It should be remembered that in many cases the appearance of the skin can improve itself over the years.

What to do against acne scars

As with other scars, acne scars can not be fully restored. In many cases, however, an improvement in the skin condition can be achieved. Depending on the type of scar, different methods with varying degrees of success are used:

  • surgical methods that either flatten scar margins or undermine scar valleys and thereby lift them: this is done by means of punch (punch excision and elevation), scalpel or high-speed grinding and milling of the skin (dermabrasion),
  • Laser,
  • Flash lamp / Intense Pulsed-Light (IPL) technology,
  • chemical scar treatment with highly concentrated trichloroacetic acid (TCA),
  • Dermal filler ( eg hyaluronic acid, collagen, poly-L-lactic acid, calcium hydroxyapatite or fatty tissue),
  • Microdermabrasion and microneedling (the skin is superficially scratched with microfine needles under local anesthesia and thus stimulated for repair),
  • Injection of glucocorticosteroids Adrenal hormones

     directly into the acne scar,
  • Cold therapy,
  • Pressure treatment (bandages continuously apply light pressure to the scar, and the reduced blood flow slows down the metabolism in the scar tissue, causing the scar to become smooth and elastic).

What to do about hyperpigmentation

Inflammatory hyperpigmentation (postinflammatory hyperpigmentation, PIH) is caused by pigmentation associated with skin inflammation. The treatment includes especially the avoidance of UV light and consistent sunscreen with a broad-spectrum sunscreen preparation. PIH is usually difficult to treat. In practice, combinations with active ingredients of different attack points have proven successful. 

Topical therapies can affect pigmentation in a variety of ways. For this purpose, various substances are used with different effects and compatibility, eg Azelaic acid, retinoids, N-acetyl-glucosamine (NAG), niacinamide, kojic acid and various herbal substances such as soy. The effectiveness of lasers or flash lamps can not yet be conclusively assessed. Better results are achieved by means of so-called non-ablative fractionated photothermolysis. Here, by means of laser targeted and controlled heating of microscopic skin areas with the protection of the epidermis. The aim of this stimulus is to stimulate the skin’s ability to regenerate.

Chemical peels have also proven themselves. They remove the top layer of skin (stratum corneum) and accelerate the penetration of bleach. Very superficial or superficial glycolic peels can be used at low risk as adjunctive treatments. However, their effect on dark skin type and the low-lying pigment is low. Here, the use of salicylic acid peels is more likely to be considered.
