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

Brand: Osmosis Skincare
Category: [Serums and treatments](https://lovi.care/skincare/fr/best/serums)

This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, 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 sensitive skin; the serums alongside fit it better.

## Why this fit

- Offers moderate rejuvenation for your dry skin due to retinal and palmitoyl tripeptide-38 promoting cell turnover and collagen synthesis, while niacinamide and sodium hyaluronate provide hydration.
- The inclusion of lactic acid and alcohol denat. may pose a risk of irritation for your sensitive skin, and the product lacks sufficient emollients to fully address dryness.

## What the research says

- Treatment with a combination of niacinamide and hyaluronic acid improved skin aging signs and demonstrated a senomorphic effect by decreasing SASP and autocrine signaling genes in women. ([Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/))
- Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/))
- 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.

- Over-the-counter retinol products provided only weak evidence for a mild ameliorating effect on fine facial skin wrinkle lines in randomized, double-blind, vehicle-controlled trials, and major methodological flaws call the validity of positive results into question. ([The Journal of Clinical and Aesthetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/34980969/))
- A cosmetic niacinamide/peptide/retinyl propionate regimen significantly improved periorbital wrinkle appearance relative to a 0.02% tretinoin regimen at 8 weeks with comparable benefits at 24 weeks, while demonstrating significantly better tolerability in 196 women. ([The British Journal of Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20374604/))
- A novel triple-active cosmetic formulation containing 4-hexylresorcinol, retinyl propionate, and niacinamide improved the visual appearance of photoageing similarly to 0.02% tretinoin and reversed a consensus gene signature associated with ageing in female adults while causing less skin irritation. ([International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/38685700/))
- 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 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/))
- Twice daily application of retinaldehyde 0.1% and 0.05% creams for 3 months improved skin texture and hydration and reduced transepidermal water loss in 40 female Korean volunteers, with only the 0.1% cream significantly improving the melanin index. ([Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/29663701/))
- Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance. ([Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12218231/))
- Topical 0.05% retinaldehyde applied over 1 year significantly increased epidermal thickness of the temple and cutaneous elasticity compared to an emollient control group in 40 aging skin patients. ([Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473959/))
- 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/))

## Why other serums fit dry sensitive skin better

- Tocopherol succinate-loaded ethosomal gel increased skin deposition, stability, moisture, and mechanical properties in 13 human subjects compared to a control gel over 12 weeks. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35274433/))
- In 50 participants with sensitive skin, a Ceramide NP C15-containing emollient improved skin barrier function with a significant reduction in transepidermal water loss and induced modest changes in skin microbiota compared to the vehicle. ([Skin Pharmacology and Physiology, 2026](https://pubmed.ncbi.nlm.nih.gov/41758783/))
- Hydrogels containing vitamin E-loaded nanostructured lipid carriers exhibited better occlusive properties and long-lasting effects, while vitamin E-loaded nanoemulsions performed a faster skin hydration effect and were selected as more attractive for skin application. ([Colloids and Surfaces. B, Biointerfaces, 2019](https://pubmed.ncbi.nlm.nih.gov/30974262/))

## How to apply

- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

### Why is Osmosis Renew Level 4 Serum a weak match for dry sensitive skin?

This serum is a weak match because ingredients like lactic acid and alcohol denat. may easily irritate sensitive skin, and it lacks enough rich moisturizing ingredients to fully comfort dry skin. A better product of this type for dry sensitive skin needs soothing moisturizers and gentle hydrators that calm and protect without causing irritation.
Sources: [Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

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

The lactic acid and alcohol denat. in this serum may cause irritation on sensitive skin, while the formula lacks rich softening ingredients to fully comfort dry skin. To properly care for dry sensitive skin, a treatment needs soothing, highly moisturizing ingredients and barrier-supporting components that hydrate without any risk of irritation.
Sources: [Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

### What does Vitamin A do for dry sensitive skin?

Vitamin A helps build collagen and thickens skin layers, but it may cause dryness and stinging in sensitive skin. Products of this type for dry sensitive skin need soothing ingredients and gentle delivery systems to keep skin calm and comfortable.
Sources: [The Journal of Investigative Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/10692106/), [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/)

### What does Niacinamide do for dry sensitive skin?

Niacinamide helps dry sensitive skin by calming irritation and keeping moisture locked in so your face feels soft and smooth. It works to build up your skin barrier and calm redness while being very gentle and unlikely to cause irritation.
Sources: [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/), [International Journal of Pharmaceutics, 2013](https://pubmed.ncbi.nlm.nih.gov/23220080/)

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

This serum goes in the evening routine after cleansing and toning, followed by a moisturizer. A product of this type needs rich, soothing hydrators and gentle barrier-repairing ingredients to keep dry, sensitive skin calm and comfortable.

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

It is best to use vitamin C in your morning routine and this serum at night to avoid overwhelming your skin. This product is a weak match for dry sensitive skin because ingredients like lactic acid and alcohol denat. may cause irritation, and it lacks rich moisturizing ingredients to properly comfort dry skin. A product for this skin needs soothing plant extracts and rich oils or butters to keep skin calm and soft.

### How often should I use this serum?

This treatment is a weak match for your dry sensitive skin, as lactic acid and alcohol denat. may cause irritation and it lacks sufficient rich moisturizers to fully soothe dryness. Start by applying it just once a week in the evening after cleansing and toning, and use a rich cream afterward to keep your skin comfortable. To properly care for this skin type, a product needs gentle hydrators and rich barrier-supporting ingredients without drying alcohols.

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

This serum is unlikely to clog pores or cause breakouts for dry sensitive skin, but the retinal may lead to some initial peeling as skin cells turn over faster. A product of this type needs rich oils and gentle moisturizers to fully soothe dry skin without irritation.

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

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