Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your dry and sensitive skin, as Alpha-Arbutin and Niacinamide work to even skin tone, while N-Acetyl Glucosamine supports barrier repair and hydration.
- While the formula provides general skincare benefits, it lacks sufficient emollient ingredients to optimally hydrate your dry or flaky skin.
- The product is safe for your skin, with no risks of irritation due to the absence of harsh ingredients.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.
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 Alpha-Arbutin 2 Discoloration Care a weak match for dry sensitive skin?
This treatment is a weak match for your dry and sensitive skin because it lacks enough softening and moisturizing ingredients to keep dry skin comfortable and properly hydrated. A treatment for this skin needs rich hydrating and nourishing ingredients, along with skin-soothing components like ceramides, to lock in moisture and protect your skin.
Which ingredients make this treatment a poor fit for dry sensitive skin?
This treatment is a weak match for your dry and sensitive skin because it lacks sufficient rich, moisturizing ingredients to properly soften flaky areas. To truly fit this skin type, a treatment needs nourishing components like ceramides, gentle brighteners, and deep moisturizers that protect and soothe without irritation.
What does Tranexamic Acid do for dry sensitive skin?
Tranexamic acid helps dry sensitive skin by repairing the skin barrier and soothing irritation. It works well to calm redness and restore moisture without causing heavy side effects.
International Journal of Dermatology, 2014Clinical, Cosmetic and Investigational Dermatology, 2024
What does Niacinamide do for dry sensitive skin?
Niacinamide helps dry sensitive skin by calming irritation and keeping moisture locked in so your face feels soft and smooth. It works to build up your skin barrier and calm redness while being very gentle and unlikely to cause irritation.
Journal of Cosmetic Dermatology, 2004International Journal of Pharmaceutics, 2013
Where does this treatment go in a skincare routine for dry sensitive skin?
This treatment goes in your evening routine, applied after your soothing toner and before your moisturizer. While it is safe and unlikely to irritate your skin, this product of this type needs rich softening ingredients to properly comfort and hydrate dry skin.
Can I use this treatment with retinol, and in what order?
You can use this treatment with retinol, applying the treatment before your moisturizer in your evening routine. A product of this type needs rich softening ingredients to deeply hydrate and comfort dry skin.
How often should I use this treatment?
You can use this treatment in the evening, applying it after your toner and before your moisturizer. Because this product is a weak match for dry skin, a product of this type needs rich softening and smoothing ingredients to keep dry skin comfortable and properly hydrated.
Can this treatment clog pores, cause breakouts or purging for dry sensitive skin?
This treatment is unlikely to cause breakouts or irritation for your dry sensitive skin due to the absence of harsh ingredients. However, because this product type is a weak match for your skin, it needs extra rich, soft moisturizers to properly soothe and comfort dry or flaky areas.
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 post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin.
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 sensitive skin better
A formulation containing glycerol (5%) and xylitol (5%) applied twice daily for 14 days increased skin hydration, filaggrin protein quantity, interdigitation index, and biomechanical properties, and decreased transepidermal water loss compared to untreated and vehicle-treated skin in twelve volunteers with dry skin.
Acta Dermato-venereologica, 2017Glycerol accelerates barrier repair and improves stratum corneum hydration compared to untreated and base-treated sites.
Acta Dermato-venereologica, 1999In 50 participants with sensitive skin, a Ceramide NP C15-containing emollient improved skin barrier function with a significant reduction in transepidermal water loss and induced modest changes in skin microbiota compared to the vehicle.
