What it is
What it is
A vitamin C name can make a serum sound more concentrated than its label establishes. MEDIHEAL Vitamin C Brightening Serum 40ml combines niacinamide, vitamin C ingredients and moisturizing components. If you specifically want a high-strength pure vitamin C product, compare the individual ingredient figures first.
Separate the concentration labels
Niacinamide is listed at 30,000ppm and panthenol at 5,000ppm. The vitamin C ingredients are separately declared as 100ppm 3-O-ethyl ascorbic acid and 50ppm ascorbic acid. The niacinamide figure is not 3% vitamin C, and the two vitamin C materials are not simply added and relabeled as pure vitamin C. Tocopherol’s 200ppm is a separate figure as well.
Consider the whole routine
The Korean notice declares whitening and anti-wrinkle functional status, without establishing a deadline for dark-spot changes. Glycerin, betaine, several hyaluronic acid forms and Ceramide NP are present. Fragrance, capryloyl salicylic acid and gluconolactone also appear. If you already use exfoliating skincare, decide which step you need before introducing several new products together. The official period after opening is six months, rather than a generic twelve-month serum rule. Spread an appropriate amount, pat lightly and follow your own pack’s dates.
A buying question answered
The 30,000ppm, or 3%, ingredient is niacinamide. Separately, the notice lists 100ppm 3-O-ethyl ascorbic acid and 50ppm ascorbic acid. These different materials are not added together and called a pure vitamin C concentration.
Use and comparison choices
Spread an appropriate amount evenly along the facial skin texture. Pat lightly, then finish with moisturizer as needed. Stop if irritation occurs rather than rubbing or increasing the amount.
Panthecell Cream serves a different role as a finishing moisturizer with panthenol and cica ingredients.
Follow serum with the cream only if your routine needs a moisturizing finish.

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.
- 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.
- Vitamin CEWG 1
Pure, underivatised vitamin C, the most heavily researched form for antioxidant defence and tone. Unlike derivatives it acts without needing conversion in the skin, but it is highly vulnerable to light and air, browning quickly and staying stable only at low pH. That is why it often ships in airless packaging or as a powder.
A form of vitamin E that works as an oil-soluble antioxidant, which means it also protects the oils in the formula from going rancid. On skin it is understood to defend lipids against free radical damage. Studies pairing it with vitamin C are frequently cited because the two stabilise each other.
A collective name for the lipid family that builds the stratum corneum barrier alongside cholesterol and fatty acids. Actual products contain specific types such as ceramide NP, AP or EOP, and this generic listing is used when the type is not specified. The three lipid classes are understood to work best at a balanced ratio.
