## 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/))
- 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/))
- 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/))
- 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/))

## Questions and answers

### How well does iS Clinical Brightening Serum work for sensitive skin?

iS Clinical Brightening Serum is an average fit for sensitive skin because it lacks harsh ingredients and is unlikely to cause irritation while helping to even your skin tone. Treatments that fit sensitive skin better need soothing ingredients that calm redness and irritation, along with hydrating components and antioxidants.

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

This serum works for sensitive skin because it lacks harsh ingredients and does not cause irritation. A treatment of this type needs calming ingredients that soothe redness and gentle hydrators to keep sensitive skin soft and comfortable.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30022595/)

### What does Alpha-Arbutin do for sensitive skin?

Alpha-arbutin helps brighten dark spots and even out skin tone while being generally safe with a rare occurrence of irritation. It is less likely to cause redness or stinging compared to stronger treatments, making it a suitable choice for keeping sensitive skin calm.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39555866/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34356362/)

### What does Ascophyllum Nodosum Extract do for sensitive skin?

Ascophyllum Nodosum Extract is found in skincare products made for sensitive skin, but it is unlikely to help because very few marine ingredients of this type have actual clinical proof behind them. Sensitive skin needs gentle, calming ingredients and formulas that are proven to soothe easily irritated areas without causing redness.
Sources: [Marine Drugs, 2021](https://pubmed.ncbi.nlm.nih.gov/34436303/)

### Where does it go in a skincare routine for sensitive skin?

This treatment goes in your evening routine, as active serums are typically used at night for extra safety around sun exposure. Because it is an average fit for your skin, a product of this type needs soothing and hydrating ingredients like glycerin or plant extracts to keep sensitive skin calm and comfortable.

### 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 it with your retinol, though sensitive skin needs a product of this type that also includes soothing, calming ingredients and barrier-supporting hydrators to prevent irritation.

### How often should I use it?

You can use this treatment once a week in the evening to keep sensitive skin calm, and carefully use it more often if your skin tolerates it well. This type of product needs gentle soothing ingredients and safe brightening agents to help even skin tone without causing irritation.
Sources: [Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/)

### Can it clog pores, cause breakouts or purging for sensitive skin?

This serum is unlikely to clog pores or cause breakouts for sensitive skin because it lacks harsh ingredients and carries a low risk of potential breakouts. However, sensitive skin types dealing with uneven tone or dark spots often do better with products that combine soothing ingredients like centella asiatica or niacinamide with gentle brightening agents to support the skin barrier while evening out pigmentation.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30022595/)

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

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