## 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 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/))
- Application of an alpha-bisabolol-containing cream produced a significant skin-lightening effect in pigmented skin compared to a vehicle control in the majority of female subjects after 8 weeks. ([International Journal of Cosmetic Science, 2010](https://pubmed.ncbi.nlm.nih.gov/20642768/))
- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Topical malassezin applied twice daily decreased epidermal melanin and reduced melanocyte dendricity in seven subjects with facial hyperpigmentation at 8 and 14 weeks, with pigmentation returning to baseline by 22 weeks. ([Journal of Drugs in Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35133118/))
- 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/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction. ([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days. ([BMC Oral Health, 2019](https://pubmed.ncbi.nlm.nih.gov/31311529/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))
- The combination of allantoin, bisabolol, D-panthenol and dipotassium glycyrrhizinate reduces UVB-induced PGE2, inflammatory cytokines, and mitochondrial superoxide in human epidermal keratinocytes. ([International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/38433250/))

## Why other serums fit skin with dark spots better

- Treatment with 14% ferulic acid and 12% l-ascorbic acid significantly reduced pigmentation and erythema while improving hydration and elasticity in 20 women with photoaged skin, with neither acid proving definitively more effective overall though ascorbic acid showed slightly greater skin lightening. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/34877760/))

Niacinamide, malassezin, and rhododendron ferrugineum extract make this serum a fit by helping to improve uneven skin tone and texture. A treatment for dark spots needs a blend of powerful antioxidants, calming components, and ingredients that repair the skin without causing irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

### What does Malassezin do for skin with dark spots?

Malassezin helps fade dark spots by reducing excess pigment in the skin when used consistently over several weeks. Studies show it targets the cells that create pigment, though color may gradually return after stopping use.

### What does Niacinamide do for skin with dark spots?

Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

### Where does this serum go in a skincare routine for skin with dark spots?

Apply this serum in the evening after cleansing and toning, and before your moisturizer. Putting treatments in the evening keeps things simple and helps avoid extra sun exposure.

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

You can use this serum with retinol by applying it at a different time of day or alternating nights to keep your skin calm. To fade dark spots effectively, this skin type needs targeted brightening ingredients like niacinamide and alpha-bisabolol.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2010](https://pubmed.ncbi.nlm.nih.gov/20642768/)

You can use this treatment in the evening as part of your routine. A product for dark spots needs targeted brightening ingredients like vitamin C, retinoids, or targeted acids to give you better results.

### Can this serum clog pores, cause breakouts or purging for skin with dark spots?

This serum is unlikely to clog pores or cause breakouts for skin with dark spots because it is free of harsh ingredients, though an average fit for your skin type means you may need a formula with extra exfoliating ingredients like acids or retinoids to better clear dark spots.
