Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- 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.
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.

What does Niacinamide do for dry skin?
Niacinamide helps dry skin by strengthening the skin barrier, increasing hydration, and reducing water loss. It supports ceramide production and helps keep the surface smooth and calm. This ingredient tends to be very well tolerated and is unlikely to irritate dry skin.
Journal of Cosmetic Dermatology, 2004Journal of Cosmetic Dermatology, 2026
What does Polyhydroxy Acid do for dry skin?
Polyhydroxy Acid helps keep dry skin hydrated and comfortable while smoothing its surface without causing irritation or barrier damage. It effectively binds moisture and supports the skin barrier while delivering gentle anti-aging benefits.

This exfoliant goes in your evening routine once a week to start, with some people working up to using it more often if they tolerate it well. It is safe for your dry skin and is unlikely to cause irritation.
Can I use this exfoliant with retinol, and in what order?
You can use this exfoliant with retinol by applying the exfoliant first in your evening routine, followed by your retinol and moisturizer, but only use them on alternate nights to prevent irritation.

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, 2017Combining 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, 2023Lactobionic acid produced better skin performance with a lack of skin irritation and barrier impairment compared to glycolic acid in 77 healthy volunteers.

Dermatologic Surgery, 2005The 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, 2020Ten 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, 2001Niacinamide/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, 2012Treatment 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, 20242-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.
