The best ingredients and treatments to reduce the appearance of post-acne scars
Posted by Ivatherm
Acne is a common skin condition that causes lesions, especially on the face, forehead, chest, shoulders, and upper back, and although more common among adolescents, it can appear at any age.
Acne occurs when hair follicles are blocked by sebum and dead skin cells. This leads to the formation of closed and open comedones (whiteheads and blackheads) and inflammatory lesions, which, as a rule, leave scars on the skin when they heal.
Inflammatory acne lesions are papules (small, red bumps), pustules (small, red pimples with pus at their tips), nodules (bumps, often painful, that develop under the skin's surface), and cysts (large, usually painful, pus-filled bumps under the skin). These lesions form through abnormal keratinization and follicular obstruction, bacterial proliferation with Propionibacterium acnes inside the follicle, and the onset of inflammation.
After acne lesions heal, the skin may develop a rough, uneven texture. Acne scars are especially common in severe forms of this inflammatory condition.
Post-acne scars, which can affect both skin tone and texture, can persist long after the condition has healed. However, there are effective ingredients and treatments to reduce the appearance of post-acne scars, so that the skin can regain its radiance.
In this article, we explain the main types of scars (atrophic, hypertrophic, keloid, hyperpigmentation) and present the most effective active ingredients for their fading, such as retinoids, AHAs, salicylic acid, or niacinamide. We also analyze modern dermatological treatments, from chemical peels to microneedling and laser therapy.

Types of post-acne scars
Scars appear when a breakout forms in the deeper layers of the skin and damages tissues. There are several types of scars, each responding differently to treatments. Thus, some treatments are better for certain types of scars than others, which is why it is necessary to know what types of post-acne scars exist.
Atrophic scars
Atrophic scars appear as small depressions or indentations on the skin's surface and are more common on the face. They result from tissue loss during the healing process of inflammatory acne. Atrophic scars form when the amount of collagen produced is insufficient during wound healing. There are three types of atrophic scars:
Ice-pick scars. These are narrow, V-shaped scars that can penetrate deep into the skin. They can look like round or oval pits, like a chickenpox scar. These are the most difficult to treat because they can extend far below the skin's surface.
Boxcar scars. These are wide, U-shaped scars with sharp edges. They can be superficial or deep. The shallower they are, the better they respond to skin resurfacing treatments. Dermabrasion and gentle exfoliation are excellent for almost all skin types with such scars.
Rolling scars. These are scars in the form of wide depressions and usually have rounded edges and an irregular appearance.
Hypertrophic scars
Hypertrophic scars form as a result of excessive collagen production during the healing process, leading to a "raising" of the skin's surface. Unlike atrophic scars, hypertrophic scars are raised and have a thick texture. They appear mainly on the chest and back.
Hypertrophic scars are more common in people with a genetic predisposition to scar formation.
Discoloration remaining after a pimple has disappeared is not a scar. Purple, red, or brown marks will disappear on their own within a few months. These are called post-inflammatory hyperpigmentation spots.
Keloid scars
This type of scar occurs when a scar continues to grow and becomes larger than the original wound. This usually happens when the collagen level in the skin is too high. Collagen is a protein found throughout the body and is effective in the wound healing process, but when the body produces too much, keloid scars can form. These are more common on the earlobes, shoulders, cheeks, and chest.
A keloid scar is not harmful to physical health, but it can cause emotional distress.
Dark spots, which appear due to hormonal changes (which are a trigger for acne), vary in shade and may be more visible in people with darker skin tones. Fortunately, acne-induced hyperpigmentation is temporary and can disappear over time with a proper skincare regimen.
Specialists recommend that before starting any treatment for acne scars, we consult a dermatologist who can determine the best method to reduce the appearance of scars.
Effective ingredients to reduce the appearance of post-acne scars
Fading the appearance of post-acne scars is a gradual process that requires constant effort. First, cleansing the affected skin with gentle products helps prevent further irritation and supports the healing process.
Also, because sun exposure can worsen the appearance of scars, protective measures are necessary. Using a broad-spectrum sunscreen with at least SPF 30 is a mandatory measure.
Therefore, a consistent skincare routine can contribute to reducing the appearance of post-acne scars. Several products contain ingredients that help improve the appearance of scars over time, but the most important thing is to properly treat acne, thus avoiding the appearance of post-acne scars.
Retinoids
Retinoids, including retinol and Granactive Retinoid, are vitamin A derivatives that support cell renewal and stimulate collagen production. They can effectively treat atrophic scars by improving skin texture and reducing an uneven appearance.
However, they make the skin particularly sensitive to the sun. Therefore, in the morning, it is necessary to apply a sunscreen.
Retinoids are found in numerous cosmetic products – from cleansers to serums – but, as they are available in different concentrations, a specialist check-up is necessary before integrating them into your skincare routine.
Alpha-hydroxy acids (AHA)
Alpha-hydroxy acids, such as glycolic acid and lactic acid, are excellent exfoliants that can help treat acne and fade post-acne scars, as well as improve overall skin texture. They work by removing dead skin cells, supporting cell renewal.
Alpha-hydroxy acids (AHAs) are often found in products intended for treating acne, as they help remove dead skin and prevent clogged pores. However, AHAs can also help reduce the appearance of acne scars. They are effective for all types of post-acne scars.
Recent studies have shown that glycolic acid has antibacterial and antioxidant properties, which helps improve the skin's appearance in people suffering from acne.
Also, a small 2010 study showed that lactic acid peels performed once every two weeks for 3 months improved skin texture, appearance, and pigmentation, and attenuated acne scars.
Salicylic acid
Salicylic acid is a beta-hydroxy acid (BHA), primarily used in acne treatment because it has exfoliating properties to remove dead skin cells, thus unclogging pores, and is also anti-inflammatory and antibacterial.
This BHA penetrates deep into the pores, making it an excellent choice for treating and preventing acne. It also helps fade post-acne scars by exfoliating the skin and reducing inflammation.
Salicylic acid is found in almost all types of acne treatments. When applied topically, salicylic acid cleans pores, reduces inflammation and redness, and exfoliates the skin. It is considered one of the best treatments for acne scars.
It usually takes a few weeks to see the effects of salicylic acid on the skin. It is also important to know that salicylic acid can dry or irritate the skin, especially in cases of skin sensitivities. To achieve the best results, it is advisable to consult a specialist.
Vitamin C
Vitamin C is one of the most powerful antioxidants that helps brighten skin and fade post-acne hyperpigmentation. It inhibits melanin production, the pigment responsible for dark spots, and supports collagen production, aiding the skin's natural healing process.
Niacinamide
Niacinamide is a form of vitamin B3, known for its anti-inflammatory and skin-brightening properties. It helps fade post-acne marks and reduces redness caused by inflammation, promoting a more even skin tone.
Niacinamide helps neutralize free radicals and maintain healthy skin. Its anti-inflammatory properties reduce the risk of skin damage, repair the skin's protective outer layer, and help manage hyperpigmentation when applied topically.
Mimosa Tenuiflora
Mimosa Tenuiflora has regenerative properties, being effective in treating and healing wounds, sunburns, scars, and various skin conditions. The cicatrizing properties of Mimosa Tenuiflora extract have been scientifically studied, with the main biological activity attributed to its high content of tannins and saponins.
Mimosa Tenuiflora extract can help reduce inflammation and relieve pain, being effective in treating conditions such as acne, herpes, and atopic dermatitis.
Mimosa Tenuiflora extract is one of the ingredients used in Ivatherm products from the Cicaderm range for damaged skin repair. Applying the product as early as possible to fresh lesions significantly improves healing.
Cicaderm Repair Cream with Mimosa Tenuiflora – for sensitive skin with lesions, helps rapid healing of skin lesions and reduces the risk of scar formation. Applied immediately to the lesion, it stops bleeding, reduces inflammation, and helps reconstruct skin integrity. It creates favorable conditions for aesthetic scarring of small wounds, scrapes, burns, lesions from chickenpox and acne, post-laser and microsurgery scars, and after hair removal.
Treatments for fading post-acne scars
For some post-acne scars, dermatocosmetic procedures in the dermatologist's office are necessary.
Chemical peeling
Chemical peeling involves applying a chemical solution to exfoliate the upper layers of the skin, revealing smoother, brighter skin. Depending on the depth and severity of the scars, different types of chemical peels can be used to target specific problems.
Various types of acids and powerful ingredients are used for chemical peels to remove the upper layer of the skin and reduce deeper scars.
Dermabrasion
Considered one of the most effective and common treatments for post-acne scars, dermabrasion involves using specific instruments to deeply exfoliate the upper layer of the skin. This cosmetic procedure is performed under anesthesia.
It is an effective method especially for atrophic scars, namely boxcar and rolling scars.
Microneedling
Microneedling is a minimally invasive procedure that involves using tiny needles to create controlled micro-injuries in the upper layer of the skin. This process stimulates collagen production and can improve the appearance of atrophic scars.
There is evidence suggesting that microneedling helps reduce the depth of acne scars. However, it can take up to 9 months to notice changes.
Laser therapy
Laser treatments, such as fractional laser and intense pulsed light (IPL), can target specific scar areas, stimulating collagen production and reducing the appearance of scars.
Laser treatment removes the top layer of skin and has a faster healing time than other cosmetic procedures.
Laser therapy is effective for all types of post-acne scars.
Dealing with post-acne scars can be a daunting process, but with the right ingredients and treatments, these imperfections can be reduced over time. Skincare products with vitamin C, retinoids, niacinamide, and acids help properly treat acne, minimize scars, and improve skin texture. For more prominent scars, professional treatments such as chemical peels, microneedling, and laser therapy can provide beautiful results.
