## 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/))
- Treatment with a combination of niacinamide and hyaluronic acid improved skin aging signs and demonstrated a senomorphic effect by decreasing SASP and autocrine signaling genes in women. ([Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/))
- 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/))
- Citrus junos callus extract decreased melanin content in melanocytes 1.85-fold compared with arbutin and promoted the proliferation of and procollagen synthesis by human fibroblasts by 154% and 176% at 500 μg/mL. ([Molecules, 2017](https://pubmed.ncbi.nlm.nih.gov/29232889/))
- Yuja-peel fractions (ethyl acetate, hexane, and butanol) inhibited MMP expression, induced moisturizing factors filaggrin and serine palmitoyltransferase, and decreased melanin content in UVB-irradiated HaCaT, HDF, and α-MSH-treated B16F10 cells. ([Antioxidants, 2022](https://pubmed.ncbi.nlm.nih.gov/36670913/))
- Upcycled low-molecular-weight anionic peptides from Citrus junos seeds protected UVR-irradiated keratinocytes and reconstructed skin tissue by scavenging reactive oxygen species, reducing paracrine cytokines, inhibiting melanin synthesis and TRP-2 expression, and increasing filaggrin, laminin-5, and type I collagen expression. ([International Journal of Molecular Sciences, 2024](https://pubmed.ncbi.nlm.nih.gov/38338991/))
- 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/))
- 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 mature skin better

### Where does this serum go in a skincare routine for mature skin?

This treatment goes in your evening routine, after cleansing and toning and before moisturizing, for simplicity and extra safety around sun exposure. Mature skin of this type needs products rich in firming peptides, nourishing retinoids, and deep hydrators to truly target fine lines and loss of firmness.

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

You can use this serum with retinol by applying the serum first in your routine and following it with your retinol.
