## 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 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/))
- Emulsions containing ceramides 1 and 3 improved skin hydration and reduced transepidermal water loss in sodium lauryl sulfate-irritated skin of fifteen healthy Asian women compared to a control emulsion. ([International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/))
- 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 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/))

### Which ingredients make this serum a good fit for skin with dark spots?

This serum is a great fit for skin with dark spots because it contains niacinamide and sodium hyaluronate, which work to brighten and deeply hydrate your skin. Ingredients like glycerin and ceramides further support your skin barrier and help keep it healthy.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Hyaluronic Acid do for skin with dark spots?

Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.

### 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?

This serum goes in the evening routine after cleansing and before moisturizing, as treatments with active ingredients are best used then for simplicity and extra safety around sun exposure. It contains niacinamide and sodium hyaluronate, which help hydrate and brighten skin with dark spots.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/)

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

Yes, you can use this serum with retinol by applying the serum first to hydrate and help your skin tolerate the retinol better. Using a barrier-supporting product with ceramides and soothing ingredients is unlikely to cause irritation and may make your retinoid routine more comfortable.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/), [International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/)

### How often should I use this serum?

This serum fits your skin with dark spots very well, and you can safely apply it in the evening as part of your routine. Ingredients like niacinamide and sodium hyaluronate hydrate and brighten your skin while keeping irritation unlikely.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/)

### 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, as reviewers rarely report reactions and the formula is gentle. Ingredients like niacinamide and sodium hyaluronate help hydrate and brighten your skin without causing irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Can I use this serum around the eyes or on my body?

You can use this moisturizing treatment safely on the body, though the skin around the eyes is much thinner and requires careful testing to avoid irritation. The gentle formulation and hydrating ingredients help support delicate areas, but you should monitor how your skin responds.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/)

### Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetyl alcohol is a fatty alcohol, which soften the skin.
