This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other serums fit it better.

## Why this fit

- Offers moderate brightening for your oily skin due to Diglucosyl Gallic Acid and Niacinamide, which help even skin tone, though it lacks sufficient mattifying ingredients for optimal oil control.
- The formula provides general hydration and soothing benefits, which you will notice, but these are not targeted for your oily shine concerns.
- The product is safe for your oily skin with no risks of irritation from harsh ingredients.

- 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/))
- Diglucosyl gallic acid exhibits stronger tyrosinase inhibition than VC with an IC50 of 2.68 mg/mL, and its application as a cosmetic ingredient improves skin brightness while reducing ultraviolet spots, melanin, and erythema in human volunteers. ([International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/))
- 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/))
- 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 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/))
- Grapeseed oil-loaded dermocosmetic nanoemulgel applied on the cheeks of healthy volunteers significantly reduced skin melanin, erythema, sebum production, and pores while increasing moisture and elasticity compared to a placebo. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35713012/))
- Topical treatment with cranberry oil and grape oil improved wound healing in rats, with cranberry oil showing an 88.1% wound area reduction and grape oil showing 84.6% compared to 74.1% in controls and 78.4% in the mupirocin standard group on day 13. ([Phytotherapy Research, 2011](https://pubmed.ncbi.nlm.nih.gov/21305631/))

- Topical CE Ferulic plus resveratrol BE serum following ablative fractional CO2 laser treatment reduced erythema index (308.9 vs. 325.3), shortened complete scabbing detachment time (6.0 vs. 6.5 days), decreased melanin index (-7.4% vs. +0.2%), and improved skin hydration compared to normal saline in 51 Chinese patients. ([Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38828801/))
- Topical treatment with a combination of pyridine-2, 4-dicarboxylic acid diethyl ester and resveratrol significantly increased hair density in 79 Caucasian female subjects starting from 1.5 months compared to baseline.

- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.
