Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your normal skin, as alpha arbutin and kojic acid work to regulate melanogenesis, though specialized ingredients for targeted pigmentation treatment are present in limited concentrations.
- Sodium hyaluronate and glycerin provide humectant action, supporting general hydration, while the absence of harsh ingredients ensures no risks of irritation for your normal skin.
- The product is safe for your skin due to the absence of prohibited or harsh ingredients.
How to apply
- Apply this serum as part of your PM routine starting 3x/week and build up to daily use if your skin likes it.
- Place the serum after cleansing and toning, but before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute for it to absorb.
- Apply the serum on dry skin to help fade pigmentation effectively.
- Avoid the eye area and always use SPF 30+ during the day.

Questions and answers
How well does Seoul Ceuticals Kojic Acid Serum work for skin with dark spots?
This serum offers moderate brightening and evening of skin tone for skin with dark spots, though other products fit this skin better. To work best for dark spots, this type of product needs a blend of effective antioxidants, soothing ingredients, and specialized ingredients for targeted pigmentation treatment in higher concentrations.
Which ingredients make this serum a good fit for skin with dark spots?
This serum works for dark spots because it contains kojic acid and alpha arbutin, which help even out skin tone. To be a better fit for this skin, a product of this type needs specialized ingredients for targeted pigmentation treatment in higher concentrations along with strong antioxidants and soothing components.
What does Kojic Acid do for skin with dark spots?
Kojic acid helps fade dark spots and uneven patches by slowing down the pigment production in your skin. It is widely used to brighten stubborn discoloration, though results depend on consistent application and proper sun protection.
Biomedicine & Pharmacotherapy = Biomedecine & Pharmacotherapie, 2019
What does Alpha Arbutin do for skin with dark spots?
Alpha arbutin helps fade dark spots by slowing down the enzyme that produces skin pigment, leading to a more even skin tone. It is unlikely to cause irritation and is generally well tolerated.
Where does this serum go in a skincare routine for skin with dark spots?
This serum goes in the evening routine, as treatments with active ingredients are usually used then for simplicity and extra safety around sun exposure. Skin with dark spots works best with a treatment that includes higher concentrations of targeted brightening ingredients.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first, letting it dry completely, and then following with your retinol. Because this serum has exfoliating acids, combining it with retinol may increase the likelihood of dryness or irritation on normal skin, so you may want to start slowly on alternate nights.
How often should I use this serum?
You can use this treatment once a week to start, and if your skin feels fine and you like the results, you can carefully use it more often. A product of this type needs higher amounts of targeted brightening ingredients to fade dark spots more effectively on this skin.
Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to clog pores or cause breakouts on your skin with dark spots, as reviewer complaints about irritation and breakouts are low and the formula avoids harsh ingredients.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
What the research says

Experimental Dermatology, 2015Bioactive glycyrrhizic acid and oxymatrine ionic liquid self-assembled nanomicelles significantly promoted the transdermal permeation, subcutaneous retention, and anti-photoaging efficacy of palmitoyl pentapeptide-4 in cellular and animal models compared to unformulated peptide.
Advanced Science, 2025
Why other serums fit skin with dark spots better
Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.
The British Journal of Dermatology, 2002Treatment with 14% ferulic acid and 12% l-ascorbic acid significantly reduced pigmentation and erythema while improving hydration and elasticity in 20 women with photoaged skin, with neither acid proving definitively more effective overall though ascorbic acid showed slightly greater skin lightening.
