Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your dry skin due to Alpha-Arbutin and Niacinamide, which help to even skin tone and provide some humectant action. N-Acetyl Glucosamine Nag also supports barrier repair, but the formula lacks sufficient emollient and occlusive ingredients for optimal hydration of dry or flaky skin.
- While the ingredients offer general skincare benefits and hydration, they are not specialized enough to fully address your dry or flaky skin concerns.
- The product is safe for your dry skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
- Place the serum after cleansing and toner, but right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on slightly damp skin to help lock in extra moisture.
- Avoid the eye area and do a patch test before your first use.
People Say
★4.7Overall rating based on 100+ reviewsThis serum is highly praised for its lightweight, watery texture that absorbs quickly and layers well, making it suitable for sensitive and acne-prone skin. While many users report positive results in fading dark spots and brightening skin tone, some note that significant improvements in hyperpigmentation take several weeks of consistent use.

Questions and answers
Why is COSRX The Alpha-Arbutin 2 Discoloration Care a weak match for dry skin?
This treatment is a weak match because, while it provides moderate brightening and some moisture, it lacks enough softening and sealing ingredients to keep dry skin comfortable. A treatment for dry skin needs rich, soothing ingredients that provide deep hydration and support the skin barrier, such as propolis, ceramides, or peptides.
Which ingredients make this treatment a poor fit for dry skin?
This treatment is a weak match for your dry skin because it lacks enough softening and sealing ingredients to keep dry or flaky skin feeling comfortable and fully hydrated. To truly care for dry skin, a product of this type needs rich, soothing, and hydrating ingredients like ceramides, propolis, or peptides that deeply nourish and support the skin barrier.
What does Tranexamic Acid do for dry skin?
Tranexamic acid helps repair and strengthen the outer barrier of dry skin, which keeps moisture locked in and improves hydration. This ingredient is unlikely to cause irritation and may help soothe redness while supporting overall skin recovery.
International Journal of Dermatology, 2014Journal of Cosmetic Dermatology, 2024
What does Niacinamide do for dry skin?
Niacinamide helps dry skin by strengthening the skin barrier, increasing hydration, and reducing water loss. It supports ceramide production and helps keep the surface smooth and calm. This ingredient tends to be very well tolerated and is unlikely to irritate dry skin.
Journal of Cosmetic Dermatology, 2004Journal of Cosmetic Dermatology, 2026
Where does this treatment go in a skincare routine for dry skin?
This treatment goes in the evening routine for dry skin. Putting it at night keeps things simple and provides extra safety around sun exposure.
Can I use this treatment with retinol, and in what order?
You may use this treatment with retinol by applying the treatment first and following with a rich moisturizer to keep dry skin soft and smooth. This product is unlikely to cause irritation, but dry skin needs extra rich moisturizing ingredients to stay comfortable when combining active treatments.
How often should I use this treatment?
You can use this treatment in the evening as part of your routine. A product of this type needs rich softening and sealing ingredients along with moisture-locking helpers to properly comfort and hydrate dry or flaky skin.
Can this treatment clog pores, cause breakouts or purging for dry skin?
This treatment is unlikely to cause breakouts or irritation on dry skin due to the absence of harsh ingredients. A product of this type needs rich moisturizing ingredients and oils to keep dry skin soft and comfortable.
What the research says
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, 2002Topical 2% N-acetyl glucosamine reduced facial hyperpigmentation in an 8-week split-face clinical test, with an even greater effect observed when combined with 4% niacinamide.
Journal of Cosmetic Dermatology, 2007Topical cosmetic products containing hyaluronic acid, N-acetyl glucosamine, and gamma-amino butyric acid improved skin hydration by 24.28% to 33.60%, elasticity by 11.98%, and skin lightening by 5.26% over 2 months in 20 female participants.
Journal of Cosmetic and Laser Therapy, 2019Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations.

Journal of Cosmetic Dermatology, 2021Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.
The Journal of Investigative Dermatology, 2008Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging.
Dermatologic Surgery, 2005N-acetylglucosamine dose dependently increased hyaluronan production in cultured keratinocytes, and its combination with retinoic acid or retinol exerted a synergistic effect.
Skin Pharmacology and Physiology, 2004Exogenous N-acetylglucosamine promotes hyaluronan production while having no effect on the expression of hyaluronan-synthesizing enzymes 1, 2, and 3 mRNA in cultured human dermal fibroblasts.
Archives of Dermatological Research, 2009Global gene expression profiling and in vitro biomarker approaches in human skin equivalent cultures successfully detected specific skin barrier, matrix, and hydration responses to topical compounds including niacinamide, hexamidine, Pal-KT, Pal-KTTKS, and N-acetylglucosamine.

Why other serums fit dry skin better
A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers.
