Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- 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.
How to apply
- Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
- Place the serum after cleansing and toner, but right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on slightly damp skin to help lock in extra moisture.
- Avoid the eye area and do a patch test before your first use.

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.
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.
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.
The Journal of Investigative Dermatology, 2000International Journal of Cosmetic Science, 2017
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
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.
Is this serum fragrance-free and alcohol-free?
It contains fragrance (benzyl alcohol) and drying alcohol (alcohol denat).
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, 2021A 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, 2010A 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, 2024Topical 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, 2021Topical 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, 2008Topical 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, 2005Twice 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, 2018Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance.
Dermatology, 2002Topical 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, 1999Topical 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, 2011Topical 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, 2022Treatment 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
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, 2020Treatment 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.
