Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening for your dry skin due to alpha-arbutin and saccharum officinarum extract, which help to even skin tone and provide mild resurfacing benefits. Glycerin offers humectant action, but the formula lacks sufficient emollient or occlusive ingredients to fully address dryness.
  • The presence of Alcohol Denat and Menthol carries some risk of irritation for your dry skin.

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 iS Clinical Brightening Serum a weak match for dry skin?

This serum is a weak match because it lacks enough softening and sealing ingredients to fully address dry skin, and alcohol denat and menthol may irritate it. A product of this type needs soothing ingredients that provide significant hydration and support skin barrier health without any risk of irritation.

Pain, 2006

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

Alcohol Denat and Menthol make this serum a poor fit for dry skin because they carry a risk of irritation, and the formula lacks enough heavy softening or sealing ingredients to fully handle dryness. A treatment for dry skin needs rich, soothing hydrators, skin barrier protectors like ceramides or niacinamide, and nourishing extras like propolis, peptides, or beneficial ferments without any irritating ingredients.

Pain, 2006

What does Alpha-Arbutin do for dry skin?

Alpha-arbutin is not primarily designed to hydrate dry skin, but advanced formulations containing it may help improve moisture content and elasticity while brightening dark spots. A dry skin type needs rich moisturizers with ingredients like ceramides, hyaluronic acid, and facial oils to properly nourish the skin barrier.

Heliyon, 2023

What does Ascophyllum Nodosum Extract do for dry skin?

Ascophyllum Nodosum Extract is unlikely to provide meaningful sun protection on its own for dry skin. Skincare for dry skin needs rich, nourishing ingredients like natural oils and heavy moisturizers to keep skin soft and smooth.

Marine Drugs, 2022

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

This serum goes in the evening routine after cleansing and before moisturizing. Because this product is a weak match for dry skin and lacks enough rich softening ingredients to fully address dryness while containing ingredients that may cause irritation, dry skin needs treatments that include extra hydrating and soothing ingredients.

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

Using this serum with retinol is unlikely to be comfortable for dry skin, because the formula lacks rich softening ingredients and contains drying alcohols that may trigger irritation. To use them anyway, apply your gentle retinol product first, wait for it to absorb, and follow with a deeply nourishing moisturizer to protect your skin barrier.

How often should I use this serum?

You can use this serum in the evening once a week to start, as it is a weak match for your dry skin and carries some risk of irritation from alcohol and menthol. If your skin tolerates it well and stays calm, you may carefully use it more often. A product for this skin type needs rich moisturizing oils and butters to lock in hydration and prevent dryness.

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

This serum is unlikely to clog pores or cause breakouts for dry skin, though reviewer feedback shows a low risk of potential breakouts. Because it lacks rich smoothing or sealing ingredients to lock in moisture, dry skin needs creams or oils with rich, sealing ingredients that soften and protect dry skin.

Is this serum fragrance-free and alcohol-free?

It has no fragrance and contains drying alcohol (alcohol denat).

What the research says

  • Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations.

    Heliyon, 2023

  • Topical 30% l-menthol decreased cold pain thresholds and enhanced pain responses to suprathreshold noxious cold stimuli without affecting other stimuli in 39 healthy subjects compared to ethanol control.

    Pain, 2006

  • Topical high-concentration L-menthol consistently induces cold pain threshold elevation and increased supra-threshold cold pain sensitivity in healthy volunteers, and successfully establishes cold allodynia or hyperalgesia in animals, serving as a predictable surrogate model.

    European Journal of Pain, 2014

  • A non-hydroquinone topical formulation (SKNB19) improved hyperpigmentation by 28.5% in patient self-assessment and 27% in independent reviewer assessment compared with 4% hydroquinone in 18 adult subjects, while showing significantly less irritation and better tolerability.

    Journal of Cosmetic Science, 2020

  • Combining a home-based radiofrequency device and arbutin cream reduced mMASI scores by 25.6% and melanin index by 22.8% at 8 weeks compared to baseline in 38 participants.

    Journal of Cosmetic Dermatology, 2025

  • Polyvinyl pyrrolidone-K90/Eudragit RL100 dissolving microneedle patches loaded with alpha-arbutin and resveratrol enhanced intradermal delivery by approximately 2.6 times compared to cream and slightly decreased the melanin index in human participants without causing skin irritation.

    Biomaterials Science, 2023

  • Fermented bilberry extract improved wrinkle depth, skin smoothness, roughness, firmness, elasticity, antioxidant capacity, and complexion evenness compared to a placebo in 66 subjects over 84 days.

    Nutrients, 2024

  • Topical application of oil-in-water creams containing wild bilberry leaves extract and seeds oil produced significant beneficial effects on the skin of healthy human volunteers.

    Antioxidants, 2021

  • Bilberry fruit extract incorporated into chitosan-based hydrogels demonstrated antioxidant, anti-hyaluronidase, and anti-tyrosinase activities, supporting their potential use in topical anti-aging preparations.

    Antioxidants, 2024

  • A botanical face cleanser with hops and willow bark extract continuously reduced skin sebum levels without reactive seborrhea after treatment in 21 healthy volunteers compared to a sodium laureth sulfate cleanser, with neither cleanser causing skin irritation.

    Journal of Cosmetic Dermatology, 2019

  • Bioactive lipid nanocarriers co-loaded with willow bark or ivy leaf extracts and UV-filters provided pronounced UVA photoprotection up to an SPF-equivalent value of 13 and a maximum in vivo skin hydration effect of 97% when prepared with pomegranate oil.

    Nanomaterials, 2022

  • A topical serum containing 0.5% salicin applied twice daily reduced visible signs of skin aging, including wrinkles and tactile roughness, in 30 female subjects over 12 weeks compared to baseline.

    Journal of Cosmetic Dermatology, 2010

  • Repeated short-contact 70% glycolic acid peels provided superior results in atrophic acne scars compared to daily low-strength glycolic acid cream or placebo in 58 women over 24 weeks.
