## Key ingredients

Tranexamic Acid, Niacinamide, N-Acetyl Glucosamine Nag

## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Topical 2% N-acetyl glucosamine reduced facial hyperpigmentation in an 8-week split-face clinical test, with an even greater effect observed when combined with 4% niacinamide. ([Journal of Cosmetic Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17348991/))
- Topical treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated. ([Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- N-acetylglucosamine dose dependently increased hyaluronan production in cultured keratinocytes, and its combination with retinoic acid or retinol exerted a synergistic effect. ([Skin Pharmacology and Physiology, 2004](https://pubmed.ncbi.nlm.nih.gov/14976384/))
- Exogenous N-acetylglucosamine promotes hyaluronan production while having no effect on the expression of hyaluronan-synthesizing enzymes 1, 2, and 3 mRNA in cultured human dermal fibroblasts. ([Archives of Dermatological Research, 2009](https://pubmed.ncbi.nlm.nih.gov/19247681/))
- Global gene expression profiling and in vitro biomarker approaches in human skin equivalent cultures successfully detected specific skin barrier, matrix, and hydration responses to topical compounds including niacinamide, hexamidine, Pal-KT, Pal-KTTKS, and N-acetylglucosamine. ([Journal of Drugs in Dermatology, 2009](https://pubmed.ncbi.nlm.nih.gov/19623777/))

## Questions and answers

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

This treatment works moderately well for your acne-prone skin, as Alpha-Arbutin and Niacinamide help even out skin tone while N-Acetyl Glucosamine provides calming benefits for blemishes. Because other options fit this skin type better, an acne-prone skin product needs soothing ingredients like niacinamide and propolis or zinc PCA to provide balanced hydration without excess oiliness or irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Alpha-Arbutin and Niacinamide help brighten your skin and calm breakouts, while N-Acetyl Glucosamine evens out your skin tone and soothes blemishes. A treatment for acne-prone skin also needs ingredients like niacinamide, propolis, or zinc PCA that balance oil and hydration without causing irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Tranexamic acid helps calm red marks left behind by breakouts and reduces inflammatory bumps like pimples on acne-prone skin. It is unlikely to cause irritation and works well to improve uneven skin tone without significant side effects.
Sources: [Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35388589/), [Journal of Research in Medical Sciences, 2023](https://pubmed.ncbi.nlm.nih.gov/37213446/)

### What does Niacinamide do for acne-prone skin?

Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/), [Cureus, 2024](https://pubmed.ncbi.nlm.nih.gov/38725769/)

### Where does this treatment go in a skincare routine for acne-prone skin?

This treatment goes in the evening routine for acne-prone skin, as active serums are usually used at night for simplicity and extra safety around sun exposure. Because this product offers an average fit, acne-prone skin needs products that use ingredients like niacinamide and tranexamic acid to brighten skin and calm breakouts.

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

You can use this treatment with retinol, but since this skin needs products that calm blemishes and support the skin barrier, apply your retinol first and follow with this treatment to keep your skin smooth and clear.

### How often should I use this treatment?

You can use this treatment in the evening as part of your routine. Acne-prone skin works best with brightening treatments that include niacinamide, tranexamic acid, and soothing ingredients to calm blemishes.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

This treatment is unlikely to clog pores or cause breakouts for acne-prone skin, as it has a very low risk of irritation and features soothing ingredients like N-Acetyl Glucosamine to help calm blemishes. Acne-prone skin often benefits most from lightweight, oil-free formulas with calming ingredients that tackle spots without heavy residues.
