This fit is calculated for the concerns frequently associated with acne-prone skin: breakouts, blackheads, and post-acne marks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for acne-prone skin; other serums fit it better.

## Why this fit

- Offers moderate brightening for your combination skin due to alpha-arbutin and saccharum officinarum extract, which help to even skin tone and provide mild exfoliation. Willow bark extract further supports this with its keratolytic and anti-inflammatory properties, making it suitable for your skin type.
- While it offers general hydration and cleansing benefits, the formula lacks targeted ingredients like salicylic acid or benzoyl peroxide to effectively treat your acne, blemishes, and breakouts.
- The product is generally safe for combination skin, though alcohol denat and menthol may pose a slight risk of irritation.

## 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](https://pubmed.ncbi.nlm.nih.gov/37681127/))
- Cooling skin temperature or applying topical menthol reduced histamine-induced itch intensity and flare diameters in healthy male volunteers. ([Neuroscience Letters, 1995](https://pubmed.ncbi.nlm.nih.gov/7624016/))
- 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](https://pubmed.ncbi.nlm.nih.gov/16527405/))
- 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](https://pubmed.ncbi.nlm.nih.gov/33022197/))
- 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](https://pubmed.ncbi.nlm.nih.gov/39918262/))
- 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](https://pubmed.ncbi.nlm.nih.gov/37183632/))
- 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](https://pubmed.ncbi.nlm.nih.gov/39064646/))
- 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](https://pubmed.ncbi.nlm.nih.gov/33809607/))
- 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](https://pubmed.ncbi.nlm.nih.gov/38247529/))
- 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](https://pubmed.ncbi.nlm.nih.gov/30022595/))
- 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](https://pubmed.ncbi.nlm.nih.gov/35889587/))
- 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](https://pubmed.ncbi.nlm.nih.gov/20883292/))
- 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. ([International Journal of Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/11095203/))

## Why other serums fit acne-prone skin better

- Topical menthol induced significant pain, cold sensations, punctate and cold hyperalgesia, and increased cutaneous perfusion in 10 subjects compared to ethanol control, acting as a human model for cold pain by sensitizing peripheral cold C nociceptors and activating cold-specific A delta fibres. ([Brain, 2004](https://pubmed.ncbi.nlm.nih.gov/14985268/))
- Topical nicotinamide plus an antibacterial adhesive agent and zinc-pyrrolidone carboxylic acid combined with adapalene significantly reduced noninflammatory acne lesions by the second week of therapy compared to placebo with adapalene in patients with moderate acne vulgaris. ([The Journal of Clinical and Aesthetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32983333/))
- A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo. ([Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/))

## Questions and answers

### How well does iS Clinical Brightening work for acne-prone skin?

This serum works moderately well for acne-prone skin, providing gentle brightening and mild exfoliation, but it lacks targeted blemish-fighting ingredients like salicylic acid or benzoyl peroxide. It is generally safe, though alcohol and menthol may carry a slight risk of irritation. Acne-prone skin needs products with ingredients like niacinamide, propolis, or zinc PCA that balance oil, hydrate, and target breakouts without irritation.
Sources: [Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/)

### Which ingredients make this serum a good fit for acne-prone skin?

Alpha-arbutin, sugarcane extract, and willow bark extract help even skin tone and gently clear pores, making the serum a moderate fit for your skin. However, since this skin needs ingredients like niacinamide, propolis, zinc PCA, or salicylic acid to properly target breakouts and keep skin balanced without irritation, this type of product requires those additions to work best.

### What does Alpha-Arbutin do for acne-prone skin?

Alpha-arbutin is primarily used to fade dark spots and uneven tone rather than treat acne, so it is a weak fit for acne-prone skin. To care for blemish-prone skin, a product of this type needs soothing and clarifying ingredients that help keep pores clear and calm redness.

### What does Ascophyllum Nodosum Extract do for acne-prone skin?

Ascophyllum Nodosum Extract helps calm red, irritated skin and keeps pores clear, making it a great addition to your routine if you deal with breakouts. It helps balance oil and soothe the skin without feeling heavy.

### Where does this serum go in a skincare routine for acne-prone skin?

This serum goes in your evening routine, as treatments with active ingredients are used then for simplicity and extra safety around sun exposure. While it offers some brightening and soothing benefits for your skin, acne-prone skin needs products with targeted ingredients like salicylic acid or benzoyl peroxide to effectively treat blemishes and breakouts.

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

You can use this serum with retinol by applying the serum first and following with your retinol. Because this formula lacks acne-fighting ingredients, an acne-prone routine needs targeted components like salicylic acid or benzoyl peroxide.

### How often should I use this serum?

You can use this treatment in the evening as part of your routine. While it is generally safe for your skin, alcohol denat and menthol may pose a slight risk of irritation. Acne-prone skin needs a product of this type that also contains targeted ingredients like salicylic acid or benzoyl peroxide to effectively treat blemishes and breakouts.

### Can this serum clog pores, cause breakouts or purging for acne-prone skin?

This serum is unlikely to cause major breakouts, but it lacks targeted ingredients like salicylic acid or benzoyl peroxide to effectively treat acne. An acne-prone skin needs blemish-fighting ingredients and exfoliants like salicylic acid to clear pores and prevent breakouts.

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

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