## Why this fit

- Highly suitable for your normal skin, Tranexamic Acid and Niacinamide work to regulate melanogenesis and repair the skin barrier, offering moderate brightening by evening skin tone.
- While the product provides general skincare benefits like hydration and soothing, its primary function is supportive rather than directly targeting your main goal of pigmentation.
- The formula is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## 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 cosmetic products containing hyaluronic acid, N-acetyl glucosamine, and gamma-amino butyric acid improved skin hydration by 24.28% to 33.60%, elasticity by 11.98%, and skin lightening by 5.26% over 2 months in 20 female participants. ([Journal of Cosmetic and Laser Therapy, 2019](https://pubmed.ncbi.nlm.nih.gov/30040516/))
- 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/))
- Topical 2% niacinamide significantly decreased sebum excretion rate in Japanese individuals and casual sebum levels in Caucasian individuals compared to placebo or baseline. ([Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/))
- 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.
