Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening for your normal skin due to alpha arbutin and kojic acid, which help even skin tone, while glycerin provides essential hydration.
  • While the serum offers general hydration and soothing benefits from ingredients like aloe and centella asiatica, it is not specialized to address your primary concerns of redness and irritation.
  • The product is safe for your sensitive skin, as it lacks harsh ingredients and includes soothing components like aloe barbadensis leaf juice and centella asiatica extract.

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 Seoul Ceuticals Ultra Brightening Kojic Acid Serum work for sensitive skin?

This serum works moderately well for sensitive skin, offering safe brightening and hydration, though it is not specialized for redness and irritation. Treatments that fit sensitive skin better need soothing ingredients like niacinamide or snail secretion filtrate to calm redness while being gentle on the skin.

Indian Journal of Pharmaceutical Sciences, 2016

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

Aloe barbadensis leaf juice and centella asiatica extract make this serum safe and calming for sensitive skin, as they help soothe the skin and provide gentle moisture. To be an even better fit for sensitive skin, a treatment of this type needs ingredients that specifically target redness and irritation while avoiding any harsh components.

Indian Journal of Pharmaceutical Sciences, 2016Clinical, Cosmetic and Investigational Dermatology, 2017

What does Kojic Acid do for sensitive skin?

Kojic acid may help fade dark spots, but it is less than ideal for sensitive skin because it carries a notable risk of irritation and contact allergy. To treat dark spots safely on sensitive skin, a product needs gentle brightening ingredients like niacinamide or arbutin along with soothing agents to keep the skin calm and comfortable.

What does Alpha Arbutin do for sensitive skin?

Alpha arbutin helps fade dark spots and uneven tone with a rare occurrence of irritation and a very gentle safety profile. This ingredient is unlikely to sting or cause redness, making it a well-tolerated choice for keeping sensitive skin calm while brightening.

Journal of Cosmetic Science, 2020

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

This treatment serum goes in your evening routine, applied after cleansing and toning and before moisturizing. Because sensitive skin needs products that calm redness and irritation, this serum works best when paired with gentle, hydrating ingredients like centella asiatica, licorice root extract, and aloe vera.

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

You can use this treatment with retinol by applying your retinol first at night and following with this serum, or by using them on alternate nights to lower the chance of skin irritation. Because this serum contains exfoliating acids like glycolic and salicylic acid alongside retinol, spacing them out helps keep your sensitive skin calm and comfortable.

How often should I use this serum?

You can use this serum in your evening routine once a week to start, and then carefully use it more often if your skin tolerates it well and shows good results. A product of this type needs gentle exfoliating acids, brighteners like alpha arbutin and kojic acid, and calming ingredients like aloe and licorice root extract to keep sensitive skin smooth and even.

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

This serum is unlikely to cause breakouts or clog pores on sensitive skin, as reviewer complaints about breakouts are low and the formula includes soothing ingredients like aloe and centella. However, because it contains exfoliating acids like glycolic and salicylic acid, this type of product needs to include gentle hydrators and calming plant extracts to keep sensitive skin balanced and comfortable.

Indian Journal of Pharmaceutical Sciences, 2016Clinical, Cosmetic and Investigational Dermatology, 2017

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
