## What the research says

- 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/))
- 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/))
- Twice daily application of retinaldehyde 0.1% and 0.05% creams for 3 months improved skin texture and hydration and reduced transepidermal water loss in 40 female Korean volunteers, with only the 0.1% cream significantly improving the melanin index. ([Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/29663701/))
- Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance. ([Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12218231/))
- Topical 0.05% retinaldehyde applied over 1 year significantly increased epidermal thickness of the temple and cutaneous elasticity compared to an emollient control group in 40 aging skin patients. ([Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473959/))
- 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.

Sources: [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

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

This serum goes in the evening routine after cleansing and before moisturizing, as Lovi places treatments in the PM for simplicity and extra safety around sun exposure.

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

It is best to use this serum and AHA on alternate nights or separate them into different routines to help prevent irritation on mature skin. Because both ingredients actively renew the skin, using them together may increase the likelihood of dryness and discomfort. When introducing an AHA, apply it to clean skin and follow with a rich moisturizer containing ceramides and squalane to keep the skin calm.
