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

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

## Why this fit

- Offers moderate suitability for your combination skin as retinol and niacinamide work to regulate desquamation and sebum production, respectively, aiding in texture refinement and reducing fine lines. While beneficial for general skin renewal, the retinol concentration provides moderate exfoliation that is supportive rather than primary for your acne and breakouts.
- The formula includes soothing ingredients like niacinamide and hyaluronic acid, ensuring a gentle experience without irritation for your combination skin.
- The safety profile is excellent, with no harsh ingredients and a formulation designed to be non-irritating.

## What the research says

- Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle. ([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- 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 bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging. ([The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Silicone particles encapsulating retinol increased its half-life by 9-fold and yielded 12-23% lower skin irritation in human subjects compared to Microsponge particles while maintaining biological activity. ([Journal of Controlled Release, 2018](https://pubmed.ncbi.nlm.nih.gov/29604311/))
- Topical stabilized retinol treatment induced HAS gene expression and increased hyaluronic acid production in human skin in vitro, ex vivo, and in vivo compared to vehicle. ([Archives of Dermatological Research, 2017](https://pubmed.ncbi.nlm.nih.gov/28247017/))
- 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 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 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.
