Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your normal skin due to alpha-arbutin and saccharum officinarum extract, which help to even skin tone.
- The presence of willow bark extract provides good keratolytic action and desquamation regulation, supporting your normal skin type.
- The product is safe for your sensitive skin as it lacks prohibited or harsh ingredients, ensuring no risks of irritation.
How to apply
- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

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.
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.
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.
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.
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.
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol denat).
