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 exfoliation for your dry skin due to lactic acid and retinal, which promote skin renewal but may lead to dryness.
- Glycerin and sodium hyaluronate provide humectant action, though the formula lacks sufficient emollients to fully address your dryness.

## What the research says

- 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 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/))
- 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 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. ([Annals of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/33911590/))

## Questions and answers

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

This serum is a weak match because its lactic acid and retinal offer moderate exfoliation that may lead to dryness, and while it includes glycerin and sodium hyaluronate, it lacks sufficient emollients to fully address dry skin. A product for this skin needs rich hydrating ingredients, soothing components, and skin barrier support like ceramides, propolis, or bifida fermentation to ensure optimal hydration and nourishment without irritation.
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 is a weak match because lactic acid and retinal offer moderate exfoliation that may lead to dryness. While it includes glycerin and sodium hyaluronate to draw in moisture, a treatment for dry skin needs rich oils, ceramides, and heavy softening ingredients to fully protect and comfort dry skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Vitamin A helps smooth and firm dry skin by boosting collagen production and encouraging new skin cell renewal. When using this ingredient on dry skin, a moisturizing cream with ceramides and hyaluronic acid is also needed to keep the outer barrier strong and deeply hydrated.
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 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/)

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

This treatment goes in the evening routine after cleansing and before moisturizing. Because this type of product can be drying, dry skin needs plenty of rich softening ingredients and heavy moisturizing creams to stay comfortable.

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

You can use this treatment with vitamin C, but it is best to apply vitamin C in the morning and save this serum for the evening to help prevent extra dryness on dry skin. Because this product is a weak match for your skin, dry skin needs a rich moisturizer with nourishing plant oils and ceramides to lock in moisture.

### How often should I use this serum?

Start by using this serum just once a week in the evening, as it offers moderate exfoliation that may lead to dryness on your dry skin. If your skin tolerates it well and stays comfortable, you can carefully use it more often. A product of this type for dry skin needs rich, softening ingredients and moisture-locking agents to fully comfort the skin.

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

This serum may cause peeling and dryness on dry skin because it exfoliates while lacking enough softening ingredients to comfort your skin fully. A product for this skin needs rich emollients and moisture-locking ingredients to keep dry skin smooth and calm.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

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