Sodium Hyaluronate, Peptides, Niacinamide, Squalane, Tremella Fuciformis Extract

## 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/))
- 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 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 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/))
- 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/))
- Squalane at 0.005-0.015% counteracts UVA-induced oxidative stress, inflammation, and collagen metabolism inhibition while stimulating fibroblast migration in human dermal fibroblasts. ([Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/))
- Plant-derived squalane protected human dermal fibroblasts against UVA-induced damage by counteracting ROS formation, suppressing apoptosis-related proteins p53, caspase-3, caspase-9, and PARP, and restoring the pro-survival p-Akt/mTOR pathway. ([Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40722956/))
- Snow mushroom alcohol-based hand rub gel significantly improved skin moisture better than the placebo through 180 minutes while maintaining comparable antiseptic efficacy in 20 human volunteers. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32531816/))
- Tremella fuciformis extract demonstrates potential cutaneous benefits including skin antiaging, photoprotection, wound healing, and barrier protection based on in vitro and animal models. ([Archives of Dermatological Research, 2023](https://pubmed.ncbi.nlm.nih.gov/36757441/))
- Tremella fuciformis inhibits melanogenesis by decreasing melanin content and tyrosinase expression in B16F10 cells while promoting wound healing in human HaCaT keratinocytes and Detroit 551 fibroblasts. ([In Vivo, 2022](https://pubmed.ncbi.nlm.nih.gov/35241526/))

This serum is a great fit for dark spots because it contains niacinamide and lactic acid, which help reduce uneven pigmentation. It also includes soothing ingredients like mushroom extract and aloe vera to keep the skin calm.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/)

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

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

This serum goes in the evening routine as a treatment step, applied after cleansing and before moisturizing. Putting treatments in the evening provides simplicity and extra safety around sun exposure, though some may also be used in the morning or twice a day.

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

You can use this serum with retinol by applying it before your retinol product to help keep your skin smooth and calm. Its gentle, hydrating formula is unlikely to cause irritation when layered into a routine with active treatments.

Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/)

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

This serum is unlikely to cause breakouts or clog pores on skin with dark spots because it is free of harsh ingredients and has an excellent safety profile. Only a few reviewers mention any breakouts at all.
