How it works
Mary & May is a Korean skincare label built around vegan, ingredient-forward formulas positioned as everyday, budget-conscious routine staples, and Rice Niacin 10% Triple Vitamin Serum is one of its serum entries. Niacinamide sits among the first ingredients on the list, the tone-evening, barrier-supporting active Korean formulas lean on most often, and its early position here means it is not a token dose. Panthenol (pro-vitamin B5) sits within the first ten ingredients as the formula's moisture-retention and comfort ingredient, a standard soothing base in Korean-market formulas. 3-O-Ethyl Ascorbic Acid, a stabilised vitamin C derivative, sits within the first ten ingredients. Tocopherol sits further down the ingredient list, the antioxidant vitamin E form supporting the rest of the formula against oxidation. As a serum, it functions as a treatment step layered under moisturiser in a layered Korean routine. It comes in a 80ml format.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
