The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Canada.

Brand: [La Roche-Posay](https://lovi.care/skincare/ca/brands/la-roche-posay)
Category: [Exfoliants](https://lovi.care/skincare/ca/best/exfoliators)

This fit is calculated for the concerns frequently associated with dry skin: flakiness, tightness, dehydration, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A great choice for dry skin; a few products fit it even better.

## Why this fit

- Offers moderate exfoliation for your dry skin due to the presence of glycerin, which provides humectant action, but lacks sufficient emollient ingredients to fully address dryness.
- Citric acid and gluconolactone provide mild chemical exfoliation, aiding in smoothing texture and addressing flakiness.
- The product is safe for your dry skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## 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/))
- Combining 10% gluconolactone chemical peeling with oxybrasion or microneedle mesotherapy increased skin hydration and decreased sebum, pH, and TEWL in twenty-one Caucasian women, with no significant differences between the two methods. ([Skin Research and Technology, 2023](https://pubmed.ncbi.nlm.nih.gov/37357656/))
- Lactobionic acid produced better skin performance with a lack of skin irritation and barrier impairment compared to glycolic acid in 77 healthy volunteers. ([Journal of Cosmetic Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20367666/))
- 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/))
- 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.

- Treatment with 2-mercaptonicotinoyl glycine (2-MNG) significantly reduced immediate darkening and inhibited new melanin production in subjects with melanin-rich skin compared to vehicle controls. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38372022/))
- 2-mercaptonicotinoyl glycine 0.5% ranked first with a high probability of immediate and persistent efficacy against UV daylight-induced pigmentation compared with 13 other reference molecules in women with skin phototype III. ([Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38433524/))
- Topical 2-mercaptonicotinoyl glycine (0.5% or 1%) significantly decreased high energy visible light-induced pigmentation compared to vehicle in 58 individuals with Fitzpatrick Phototype III or IV, whereas ascorbic acid 7% showed no efficacy.

## What reviewers say

Users with hyperpigmentation and dullness frequently praise this cleanser for its ability to gently exfoliate and smooth skin texture without stripping moisture. While many report a brighter, more radiant complexion, a subset of users with stubborn dark spots found it ineffective or were put off by its fragrance and residual film.

- Liked: Pleasant usage experience (often mentioned)
- Liked: Smoothes skin texture (often mentioned)
- Liked: Brightens complexion (sometimes noted)
- Disliked: Ineffective on spots (sometimes noted)

## How to apply

- Use this exfoliant as part of your PM routine once a week, increasing slowly to twice a week if your dry skin tolerates it well. Always remember to apply SPF every morning to protect your newly smoothed skin.
- Apply the exfoliant after cleansing and toning, but always before your rich moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute. Avoid rubbing to prevent any irritation on flaky areas.
- Apply the product directly to dry clean skin to ensure the best possible tolerance for your dry type. This helps address flaky patches without causing extra stress.
- Avoid the sensitive eye area and do a quick patch test before your very first use. Do not mix this with other strong acids or retinoids on the same night.
