What features should you look for in a good serum for acne scars?
Azelaic acid: This is one of the most thoroughly researched ingredients that help reduce post-acne hyperpigmentation. It inhibits excessive melanin production, has anti-inflammatory properties, and helps even out skin tone while reducing the risk of new blemishes forming.
Niacinamide: It helps lighten post-inflammatory hyperpigmentation, strengthens the skin’s protective barrier, and reduces redness. When used regularly, it improves skin tone and supports skin regeneration after acne breakouts.
Vitamin C: A powerful antioxidant that helps lighten existing hyperpigmentation and protects the skin from oxidative stress, which contributes to the formation of new pigment spots. Additionally, it supports collagen synthesis, improving the overall appearance of the skin.
Retinol or retinal: Vitamin A derivatives accelerate cell turnover, allowing the skin to shed cells containing excess pigment more quickly. Regular use helps smooth the complexion, reduce the appearance of discoloration, and improve skin texture.
Exfoliating acids (AHA, PHA): Ingredients such as mandelic, glycolic, and lactobionic acids gently remove dead skin cells and accelerate the skin’s renewal process. As a result, post-acne hyperpigmentation gradually becomes less visible, and the complexion takes on a more even tone.
Moisturizing and regenerating ingredients (e.g., hyaluronic acid, panthenol, ceramides): Intensive brightening treatments can sometimes weaken the skin’s hydrolipid barrier. The presence of moisturizing and soothing ingredients helps reduce irritation, supports regeneration, and enhances the comfort of daily serum use.
A stable and well-formulated formula: An effective serum should contain appropriate concentrations of active ingredients and have a light, fast-absorbing texture. This allows the product to be used regularly, which is crucial for the gradual reduction of post-acne hyperpigmentation.

Orphica Clinic Anti-Acne is a serum designed for problem skin that supports skin regeneration and helps reduce the appearance of post-acne marks, such as acne-related hyperpigmentation. The key ingredient in the formula is retinol—a derivative of vitamin A—which accelerates cell renewal, smooths the skin’s texture, and gradually evens out skin tone. With regular use, the skin regains a more even appearance, and acne scars become less visible. The formula has been enriched with squalane, which strengthens the hydrolipid barrier and reduces the risk of dryness often associated with retinol treatments. Hyaluronic acid, in turn, intensely hydrates the skin, improving its elasticity and enhancing the product’s comfort during use. Vitamin E provides antioxidant protection, shielding cells from oxidative stress and supporting natural regenerative processes. The lightweight, fast-absorbing texture ensures the serum spreads easily over the skin without leaving a greasy residue. This product is ideal for those who want to simultaneously promote skin regeneration, smooth the skin’s surface, and gradually reduce post-acne hyperpigmentation, while maintaining adequate hydration levels during retinol treatment.
Miya Cosmetics BEAUTY.lab Lifting Serum with Plant-Based Retinol [2.5%] is a product based on a dual plant-based retinol complex (bakuchiol + stevia), which is gentler than traditional retinol, while firming the skin and improving its elasticity. The ceramide complex [2%] supports the regeneration of the hydrolipid barrier and maintains proper hydration levels, while Japanese camellia oil smooths and softens the skin. Orange blossom hydrosol soothes, while cornflower extract improves the skin’s overall condition. The formula claims to reduce post-acne hyperpigmentation and even out skin tone, though it acts much more gently on these issues than true retinol. Our testers didn’t like that, despite its claimed moisturizing properties, the serum caused slight dryness in some people. Some testers also noted that the lifting effects and the brightening of acne-related discoloration are subtle and require several weeks of use. The testers didn’t like that the formula contains a fragrance blend that may not be suitable for very sensitive skin.
La Roche-Posay Retinol B3 Serum is a concentrated formula that combines pure retinol with sustained-release retinol (retinyl palmitate), which intensively corrects wrinkles and discoloration—including post-acne hyperpigmentation—while minimizing the risk of irritation. Retinol normalizes the skin’s natural exfoliation process and the function of the sebaceous glands, thereby preventing clogged pores. Niacinamide (vitamin B3) soothes irritation and supports the restoration of the hydrolipid barrier, while adenosine provides additional anti-wrinkle benefits. Hyaluronic acid and glycerin provide hydration, reducing the tightness typically associated with retinol. Our testers did not like the presence of silicones (cyclohexasiloxane, dimethicone) in the formula, which in some people may increase the comedogenic effect and lead to blackheads on the jawline and chin. Some testers also noted that the product contains a fragrance. Use requires daily sun protection with an SPF of at least 15.
Nacomi Next Level Retinol Serum is a product based on pure retinol in a relatively low, introductory concentration that stimulates fibroblasts to produce collagen, normalizes epidermal keratinization, and regulates sebum production. As a result, it supports acne treatment, helps unclog pores, and reduces the formation of new breakouts. Four forms of hyaluronic acid with varying molecular weights provide multi-level hydration, while panthenol, combined with flower oil extracts, soothes irritation and supports regeneration, helping to reduce post-acne hyperpigmentation. Glycerin facilitates the delivery of active ingredients into the deeper layers of the skin. Our testers didn’t like that the flower extracts (jasmine, lavender, peony) may increase the risk of allergic reactions in people with sensitive skin. Some testers also noticed dryness and slight flaking of the skin at the beginning of the treatment. The testers pointed out that the serum should not be combined with other acids or vitamin C in the same skincare routine.
SKIN1004 Madagascar Centella Ampoule is an ampoule made from 100% Madagascar Asian pennywort extract, which contains asiaticoside, madecassoside, and asiatic acid. These ingredients have anti-inflammatory and soothing properties, reducing redness and supporting the healing of skin irritated by acne. Centella asiatica also supports collagen synthesis and strengthens the hydrolipid barrier, making the skin more resilient and better hydrated. The minimalist, fragrance-free, and alcohol-free formula works well as a complement to intensive acne treatment, soothing irritation caused by acids or retinol. Our testers didn’t like the absence of typical acne-fighting ingredients, such as niacinamide or salicylic acid, which means the ampoule doesn’t reduce active breakouts or post-acne hyperpigmentation on its own, but primarily acts to soothe the skin. Some testers also noted that the very simple formulation results in subtle effects that are less noticeable than those of serums with a greater number of active ingredients.Our testers were disappointed by the liquid consistency, which makes the product less economical, and its effect on post-acne hyperpigmentation is not spectacular.
