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

A great choice for oily acne-prone skin; a few moisturizers fit it even better.

## Why this fit

- Offers excellent hydration for your oily skin, as glycerin and sodium hyaluronate provide effective humectant action without being occlusive, though it lacks targeted ingredients for your acne concerns.
- The formula is highly suitable for oily skin due to the humectant properties of propanediol and glycerin, which draw moisture to the skin without adding excess oil.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of harsh ingredients and the presence of soothing components like glycerin and sodium hyaluronate.

## What the research says

- 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 1,3-propanediol at various concentrations, alone or combined with butylene glycol and/or glycerol, increased skin hydration and reduced trans epidermal water loss in 30 healthy female subjects over an 8-hour period, with the 15% concentration and the addition of glycerol providing greater benefits. ([International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/))
- A mixture of propanediol, xylitol, and caprylic acid demonstrated in vitro antimicrobial activity against C. acnes and S. aureus, reduced 5-alpha reductase expression, and decreased skin oiliness, porphyrin, and inflammatory lesions in participants over 28 days. ([Molecules, 2021](https://pubmed.ncbi.nlm.nih.gov/34771112/))
- 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/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))
- Sustainable cosmetic products formulated with renewable PDO-based emulsifiers showed equivalent performance in sensory and moisturization evaluations compared to those formulated with petroleum-derived PEG-based emulsifiers. ([Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/29465392/))
- A multi-modal methodology combining MALDI-MSI, in vivo RCM, echography, and histology revealed age-related decreases in extracellular matrix and epidermal-dermal junction proteins and undulation depth, while a blend of palmitoyl oligopeptide and palmitoyl tetrapeptide-7 improved subepidermal low-echogenic band thickness, density, and extracellular matrix structure compared to placebo. ([Journal of Cosmetic Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25817264/))
- Palmitoyl tetrapeptide-7, acetyl hexapeptide-8, palmitoyl tripeptide-1, and palmitoyl tetrapeptide-10 significantly increased type III collagen levels in human dermal fibroblasts following UV exposure, with their combination demonstrating a greater effect in vitro and enhancing type I, III, and IV collagen levels in ex vivo skin tissues compared to individual components.
