Description
Mary & May Niacinamide + Chaenomeles Sinensis Brightening Serum 30ml is a lightweight Korean facial serum designed to improve the appearance of dullness, uneven skin tone, excess sebum and visible pores. Its minimalist formula combines a high concentration of Chaenomeles Sinensis fruit extract with 2% niacinamide to deliver daily antioxidant, brightening and skin-balancing care.
The formula contains 93% Chaenomeles Sinensis fruit extract. Also known as Chinese quince extract, this botanical ingredient contains naturally occurring antioxidant compounds, including flavonoids. It helps support skin exposed to everyday environmental stress and promotes a smoother, fresher and more radiant-looking complexion.
Niacinamide is included at a 2% concentration. This versatile form of vitamin B3 supports a brighter and more even-looking skin tone while helping improve the appearance of enlarged pores and excess surface oil. It can also complement the skin’s natural barrier function and support comfortable hydration.
The serum is suitable for customers who prefer a moderate niacinamide concentration rather than a highly concentrated 10% or 15% formula. Its 2% level makes it a practical option for daily skincare routines, including routines for sensitive or niacinamide-inexperienced skin. Individual tolerance can still vary, so patch testing remains recommended.
Glycereth-26 functions as a humectant and emollient. It helps attract moisture and gives the serum a smooth, comfortable skin feel. Caprylyl glycol and 1,2-hexanediol also contribute moisture-supporting and formula-stabilizing properties.
Arginine is an amino acid and skin-conditioning ingredient. It supports the formula’s pH balance and contributes to a comfortably hydrated finish. Carbomer creates the serum’s lightweight gel consistency, allowing it to spread easily and absorb without a heavy cream-like texture.
The complete formula contains only eight listed ingredients: Chaenomeles Sinensis fruit extract, Glycereth-26, niacinamide, 1,2-hexanediol, arginine, carbomer, ethylhexylglycerin and caprylyl glycol. This short ingredient list is useful for customers seeking focused Korean skincare without an unnecessarily complicated blend of actives.
Mary & May identifies the serum as free from artificial fragrance, artificial colour, drying alcohol, mineral oil, parabens and several other ingredients excluded under the brand’s clean-beauty standards. Independent ingredient analysis also lists the formula as alcohol-free and fragrance- and essential-oil-free.
The serum has a lightweight, fast-spreading texture suitable for layering under moisturizer and sunscreen. It can be used in both morning and evening routines after toner and before cream. During daytime use, broad-spectrum sunscreen remains necessary because a brightening serum does not replace protection from ultraviolet exposure.
With regular use, Mary & May Niacinamide Brightening Serum can help the complexion appear clearer, smoother and more balanced. Results vary according to skin condition, routine consistency and sun protection. The product supports the cosmetic appearance of pigmentation and pores but should not be described as a medical treatment for melasma, acne or other skin disorders.
