Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone for your normal skin due to alpha-arbutin and tetrahexyldecyl ascorbate, but these ingredients are not targeted for your redness and irritation concerns.
  • Sodium hyaluronate and glycerin provide hydration suitable for normal skin, while squalane offers emollient action, though these do not directly address your primary skin issues.
  • The product is safe for your normal skin with sensitivity, as it lacks harsh ingredients and has no risk 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 Complex work for sensitive skin?

This treatment is an average fit for sensitive skin because while it provides safe hydration and brightening, it does not directly target redness and irritation. Products that fit this skin better need ingredients like niacinamide and snail secretion filtrate to calm redness while keeping the skin soft and comfortable.

Heliyon, 2023Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this cream a good fit for sensitive skin?

This cream works for sensitive skin because it contains sodium hyaluronate and glycerin for hydration, alongside squalane to keep skin soft. However, a product for this skin needs ingredients that directly target redness and irritation, such as niacinamide and soothing plant extracts.

Clinical, Cosmetic and Investigational Dermatology, 2017

What does Hyaluronic Acid do for sensitive skin?

Hyaluronic acid helps calm and hydrate sensitive skin while supporting the skin barrier to keep it soft and comfortable. Clinical studies show it improves surface moisture and reduces dryness, roughness, and redness without irritation.

Journal of Drugs in Dermatology, 2025Journal of Cosmetic Dermatology, 2018

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.

Journal of Cosmetic Dermatology, 2025Antioxidants, 2021

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

Use this treatment in the evening routine, applying it after your soothing toner and before your moisturizer. Treatments with active ingredients go in the evening for simplicity and extra safety around sun exposure. This product works for sensitive skin, but to better fit this skin type, a treatment of this type needs calming ingredients like centella asiatica, allantoin, or bisabolol to directly address redness and irritation.

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

You can use this treatment with retinol by applying the treatment first and following with your retinol on alternate nights to avoid irritation. This product is unlikely to cause irritation on sensitive skin, but a product for sensitive skin needs calming ingredients and soothing plant extracts like centella asiatica or green tea extract to directly target redness and irritation.

How often should I use it?

You can use this treatment in the evening as part of your routine. It is safe for sensitive skin, but a product for this skin needs extra soothing and calming ingredients to target redness and irritation directly.

Can this cream clog pores, cause breakouts or purging for sensitive skin?

This cream is unlikely to clog pores or cause breakouts for sensitive skin because it lacks harsh ingredients and has a very safe profile. However, it does not directly target your redness and irritation concerns, so a product for this skin needs soothing ingredients like centella asiatica or niacinamide to calm sensitivity while brightening.

Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Stearyl alcohol and cetearyl alcohol are fatty alcohols, which soften the skin.
