How it works
Vitaceutical 15+ Ampoule is an ampoule serum from Dr.G. Dr.G is a Korean dermatology-brand skincare line, sold across several named ranges each built around one skin concern, including a blemish-focused range for oily and congested skin, a firming and glow range, and a separate sub-line for scalp and hair care. On this jar's own ingredient list, L Ascorbic Acid, Vitamin E, Panthenol, Ferulic Acid, Sodium Hyaluronate are named directly, which is what the key-actives panel on this page is built from rather than from the product name alone. Use it after toner and before moisturizer, as the routine's concentrated treatment step, giving it a minute to settle before the next layer goes on. Dr.G sells this as the Korean-market formula, the same one stocked on shelves in Korea rather than a version built for the US market.

Inside the formula
Inside the formula
What is Vitaceutical 15+ Ampoule?
It is Dr.G's ampoule serum (15ml). Its own ingredient list names L Ascorbic Acid, Vitamin E, Panthenol, Ferulic Acid, positioned the way the key-actives panel on this page describes, rather than actives assumed from the product name. It is used after toner and before moisturizer, as the routine's concentrated treatment step.
How do I use Vitaceutical 15+ Ampoule?
Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM. Keep the same order every time you use it so you can tell what is actually working, and give a new step a few weeks before judging the result.
Is Vitaceutical 15+ Ampoule the authentic Korean-market formula?
Yes. This listing is Dr.G's Korean-market formula: the same ingredient list, barcode and batch code as the unit sold on shelves in Korea, rather than a version reformulated for US retail. That is the whole reason to buy a Korean-market brand from a specialist rather than a general retailer.
Where does Vitaceutical 15+ Ampoule fit if I already use sunscreen or makeup?
Apply Vitaceutical 15+ Ampoule before sunscreen or makeup, and let it absorb fully first so it does not pill under the next layer. Sunscreen still goes on last in the morning, and makeup after that, regardless of how many treatment steps come before it.
Who is Vitaceutical 15+ Ampoule suited for?
It is not restricted to any one skin tone or age group. As with any new step, patch-test on the inner arm first if you are new to this formula or to Dr.G.

Ingredient list read from inkeedecoder.com on 10 September 2026.
22 of 29 explained
- Aqua solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Terminalia Ferdinandiana Fruit Extract plant extract
- Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
- Ethoxydiglycol solvent
- Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
- Glycerin humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- C12-13 Pareth-9 surfactant
- An ethoxylated fatty alcohol used as a mild surfactant and solubiliser, most often so an oil-based makeup remover will rinse away with water.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- Acetyl Glucosamine active
- Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide.
- Vitamin E (1%) antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Panthenol (1%) humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Pinus Pinaster Bark Extract plant extract
- Maritime pine bark extract, the source of the proanthocyanidins sold under the pine bark name. It is used as a plant antioxidant.
10 more explained
- Ferulic Acid antioxidant
- Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Pentylene Glycol humectant
- Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Adenosine active
- Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- Resveratrol antioxidant
- Resveratrol is an antioxidant from grape skin and Japanese knotweed. It is used for the look of dullness and is often paired with ferulic acid, which keeps it stable.
- Anthemis Nobilis Flower Extract plant extract
- Roman chamomile flower extract. It carries flavonoids and is one of the classic plant ingredients in formulas aimed at the look of reddened skin.
- Ascorbyl Palmitate antioxidant
- Vitamin C joined to palmitic acid so it dissolves in oil rather than water. It is used in oil phases, where ascorbic acid cannot go.

How to use
- Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
- Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
- Follow with a moisturizer within a minute so the thin layer has something holding it down.
- Do not stack it under a second serum doing the same job, since more layers is not the same as more result.
Worth knowing
- New to this formula or to the brand: patch-test on the inner arm and wait a day before applying it to the face.
- Discontinue use and rinse the area with water if redness, itching or irritation develops.
