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

Brand: [La Roche-Posay](https://lovi.care/skincare/uk/brands/la-roche-posay)
Category: [Serums and treatments](https://lovi.care/skincare/uk/best/serums)

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 weak match for dry skin; the serums alongside fit it better.

## Why this fit

- Offers moderate brightening and evening of skin tone due to niacinamide and phenylethyl resorcinol, but its alcohol denat content may be drying for your dry skin, and it lacks sufficient emollients to fully address dryness.
- While it provides some hydration with glycerin and sodium hyaluronate, the formula's overall balance is suboptimal for your specific dry skin needs.

## Key ingredients

Niacinamide, Thermal Water, Sodium Hyaluronate, Phenylethyl Resorcinol, Glycerin

## What the research says

- 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/))
- Nano-microneedle-assisted phenylethyl resorcinol significantly reduced the melanin index in infraorbital dark circles compared to baseline and topical-only treatment in 20 female participants without serious adverse effects. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/))
- 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.

- 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 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.

- 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/))
- Balneotherapy with thermal water altered specific skin microbiota at genus and species levels in healthy female volunteers compared to tap water, which produced no significant microbiome changes. ([Life, 2023](https://pubmed.ncbi.nlm.nih.gov/36983902/))
- Malaysian thermal spring water as an adjunct to standard acne therapy improved skin hydration, reduced dryness and stinging, enhanced overall tolerability, and improved the acne disability index in patients with mild to moderate acne. ([The Medical Journal of Malaysia, 2024](https://pubmed.ncbi.nlm.nih.gov/38553920/))
- A 2% Sphingomonas xenophaga ferment extract cream applied twice daily for 4 weeks significantly decreased facial vascular disorder scores compared to vehicle in 86 Caucasian female subjects, alongside dose-dependent inhibition of pre-kallikrein activity in vitro. ([International Journal of Cosmetic Science, 2025](https://pubmed.ncbi.nlm.nih.gov/40545753/))
- 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/))

([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/))

## Why other serums fit dry skin better

- A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/))
- Treatment with cross-linked hyaluronic acid-based microneedle patches combined with acetyl hexapeptide-8 or epidermal growth factor significantly improved wrinkles and skin hydration compared to the patch alone in Korean females over 29 days.

## Questions and answers

### Why is La Roche-Posay Pure Niacinamide 10 Serum a weak match for dry skin?

La Roche-Posay Pure Niacinamide 10 Serum is a weak match because its alcohol content may be drying for your dry skin, and it lacks sufficient nourishing and rich moisturizing ingredients to fully address dryness. A treatment for dry skin needs plenty of hydrating ingredients and barrier-supporting components like ceramides or soothing plant extracts to keep skin soft and comfortable.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this serum a poor fit for dry skin?

This serum contains alcohol denat, which may dry out your dry skin, and it lacks enough richer ingredients to fully handle dryness. Dry skin of this type needs rich, soothing ingredients, ceramides, peptides, and strong moisturizers that build up the skin barrier and provide deep hydration without any risk of irritation.

### 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.
Sources: [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/), [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/42108609/)

### What does Thermal Water do for dry skin?

Thermal water helps boost skin hydration and reduces dryness and stinging while calming the skin. It may also improve overall skin comfort and support your usual routine by keeping the skin calm.
Sources: [The Medical Journal of Malaysia, 2024](https://pubmed.ncbi.nlm.nih.gov/38553920/)

### Where does this serum go in a skincare routine for dry skin?

This serum goes in the evening routine for dry skin. A product of this type needs rich moisturizers and nourishing ingredients like ceramides, squalane, or heavier plant oils to keep dry skin soft and smooth.

### Can I use this serum with retinol, and in what order?

This serum may be too drying to easily pair with retinol on dry skin because it contains alcohol denat and lacks rich moisturizers. A product of this type needs extra soothing oils and rich butters to keep dry skin soft and comfortable.

### How often should I use this serum?

You can use this serum in the evening as part of your routine. However, because it contains drying ingredients and lacks sufficient rich moisturizers for your dry skin, a product of this type needs extra soothing hydrators and heavy smoothing oils to keep your skin soft and comfortable.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

### Can this serum clog pores, cause breakouts or purging for dry skin?

This serum is unlikely to cause breakouts for dry skin, as negative reviews about clogged pores are rare. However, dry skin needs a product with richer emollients and no drying alcohols to keep the skin feeling soft and comfortable.

### Is this serum fragrance-free and alcohol-free?

It contains fragrance (parfum) and drying alcohol (alcohol denat).
