Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening for your oily skin, as Alpha-Arbutin and Niacinamide work to regulate melanogenesis and seboregulation, supporting your goals for acne and blemishes by addressing hyperpigmentation.
  • The presence of Tranexamic Acid and N-Acetyl Glucosamine further aids in improving skin tone and texture, complementing the primary ingredients for enhanced efficacy.
  • The formula is safe for your oily skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

How to apply

  • Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
  • Apply your serum after cleansing and toning, but before putting on your moisturizer.
  • Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
  • Apply the serum on clean, dry skin to help manage your blemishes safely.
  • Do a patch test before your first use and avoid the delicate eye area.

People Say

This serum is highly praised for its lightweight, watery texture that absorbs quickly and layers well, making it suitable for sensitive and acne-prone skin.

Questions and answers

How well does COSRX Alpha-Arbutin 2 Discoloration Care work for oily acne-prone skin?

This treatment works moderately well for your oily skin to help fade dark spots and even out your skin tone. Treatments that fit oily acne-prone skin even better need ingredients like benzoyl peroxide or vitamin C alongside soothing extracts to control excess oil, clear breakouts, and keep the skin calm and comfortable.

Journal of Cosmetic Dermatology, 2007The British Journal of Dermatology, 2002

Which ingredients make this treatment a good fit for oily acne-prone skin?

Alpha-Arbutin and niacinamide help brighten your oily skin and address dark spots by evening out skin tone. Tranexamic acid and N-Acetyl Glucosamine further support your goals by improving overall skin texture safely without causing irritation. For this skin type, treatments benefit most from ingredients like niacinamide, Vitamin C, or benzoyl peroxide, combined with soothing extracts and oil-controlling properties that manage breakouts without adding heaviness.

The British Journal of Dermatology, 2002Journal of Cosmetic Dermatology, 2007

What does Tranexamic Acid do for oily acne-prone skin?

Tranexamic acid helps reduce redness and inflamed spots like pimples and pustules on oily, acne-prone skin. It may also fade lingering dark marks left behind by breakouts with a very low chance of irritation.

Journal of Research in Medical Sciences, 2023Journal of Cosmetic Dermatology, 2022

What does Niacinamide do for oily acne-prone skin?

Niacinamide helps balance oil production, calms redness, and is unlikely to irritate oily, acne-prone skin while improving blemishes. Clinical tests show it reduces excess oil and helps clear up both inflammatory and non-inflammatory acne breakouts.

Journal of Cosmetic and Laser Therapy, 2006Journal of Cosmetic Dermatology, 2024

Where does it go in a skincare routine for oily acne-prone skin?

This treatment goes in the evening routine after cleansing and before moisturizing, as evening application helps keep things simple and safe around sun exposure. Oily acne-prone skin often needs a well-rounded treatment featuring soothing, oil-balancing, and blemish-clearing ingredients to effectively improve skin tone and texture.

Can I use this treatment with retinol, and in what order?

You can use this treatment with retinol, applying it after your cleanser and toner and letting it absorb before putting on retinol and moisturizer. This product helps fade dark spots while keeping your skin calm, but for oily acne-prone skin, a treatment of this type needs ingredients like tranexamic acid, niacinamide, and alpha-arbutin to target blemishes and brighten skin tone safely.

Journal of Cosmetic Dermatology, 2007The British Journal of Dermatology, 2002

How often should I use it?

You can use this treatment in the evening as part of your routine. Products of this type for oily acne-prone skin need ingredients like Alpha-Arbutin and Niacinamide to help brighten dark spots and keep oil balanced without causing irritation.

Journal of Cosmetic Dermatology, 2007The British Journal of Dermatology, 2002

Can this treatment clog pores, cause breakouts or purging for oily acne-prone skin?

This treatment is unlikely to cause breakouts or irritation for your oily skin because it lacks harsh ingredients, though a product for this skin type still needs to be lightweight and non-greasy to keep pores clear.
