What it is

Planning repeat use of the same serum? This offer includes two 30ml bottles of Niacinamide 10 TXA 4 Serum. If you have not tried one bottle, consider whether the larger purchase unit fits your routine before committing shelf space.

Read the numbers and declaration

Niacinamide and tranexamic acid appear early, with arbutin and alpha-arbutin listed separately. The brand identifies 10% niacinamide and 4% TXA. Glycerin, panthenol, hyaluronic-acid-related materials, Ceramide NP and several plant oils are also declared. The oil entries prevent a blanket oil-free description, and ingredient numbers cannot be converted into multiples of results. Arbutin and alpha-arbutin should retain their separate identities.

Review other serums first

If Peach Serum or a niacinamide-containing toner is already in use, another serum is optional rather than compulsory. Introducing products separately makes amount, finish and individual reactions easier to assess. Avoid the eyes and stop if stinging or redness develops. The vitamin C derivative 3-O-ethyl ascorbic acid is not a pure-vitamin-C concentration declaration.

Separate one bottle and offers

This page covers two 30ml bottles. A single bottle and a refill promotion can differ in container count and packaging. The declaration follows the current Korean brand notice; prioritize your actual pack if order differs. Dark-spot naming is not a promise to treat scars or a skin disease. Maintain separate sun protection in daytime.

Store two bottles deliberately

Distinguish an opened bottle from its unopened companion; opening both at once is optional. Check each pack’s date. The current brand declaration may differ in order from older packaging; quantity alone does not establish a new formula or different results.

A buying question answered

The listing is two 30ml units, not one 60ml container. Separate it from the brand’s bottle-plus-refill offer. Buying two bottles does not call for a larger application amount or stronger concentration.

Use and comparison choices

Prepare skin at the serum step after cleansing. Spread an appropriate amount evenly, avoiding the eye area. Allow gentle absorption, then finish with moisturizer as needed.

Compare a single 30ml for a first purchase and the duo when the amount and finish already suit you. Peach Serum is a separate 5%-niacinamide formula with fragrance.

Spot Cream can be a moisture step on dry areas after serum. Both list niacinamide, so layering is a choice rather than a requirement.

What works

Niacinamide, tranexamic acid, arbutin and alpha-arbutin are declared together.

A listed ingredient has caused a reaction, or the area is wounded or reacting.

Key ingredients

NiacinamideEWG 1
A form of vitamin B3 that acts on the step where melanin transfers into skin cells, which is the basis for its use in tone-evening products. Research also covers barrier lipid production and oil control, giving it unusually broad application. In Korea it is a listed brightening functional ingredient, commonly at 2 to 5 percent.
Tranexamic AcidEWG 1
An amino acid derivative originally developed as a haemostatic drug, later established as a tone ingredient through research on the melanin pathway. Its low irritation profile means it is frequently combined with niacinamide or vitamin C derivatives.
PanthenolEWG 1
A precursor to vitamin B5 that converts to pantothenic acid once absorbed. It works in two directions at once, holding water and helping settle the skin barrier, which is why it appears in both calming skincare and hair care. Its low irritation profile makes it a regular in sensitive-skin formulas.
Glycerin
The most widely used humectant in skincare, drawing water toward the skin and holding it in the upper layers. Its interaction with the skin's own water channels has been studied for decades, and it is mild enough to appear across a very wide concentration range. At high levels it turns tacky, so formulas usually pair it with lighter humectants.
