DEMAR3 Ampoules
DEMAR3 ampoules are high-concentration treatment serums formulated for targeted skin concerns. The lineup covers three distinct axes: the DIEX Citadue Burning Ampoule for exfoliating and resurfacing, the Etcell Melatonic Ampoule for brightening and tone correction, and the Signature Estud Protector 5.2 Pore Ampoule for minimizing visible pores. The Signature Alpe Di 36 and Anti-aging Alpe Di formulas address loss of firmness and visible aging. Each ampoule is designed for layering after toner and before moisturizer, delivering actives at a higher load than a standard serum. The range spans 30 ml travel sizes up to 170 ml clinic-scale bottles so you can trial a formula before committing to the full size.

DEMAR3 Ampoules: Which Formula Fits Your Skin Goal
DEMAR3 builds each ampoule around a single, well-defined skin objective rather than a generic multi-action brief. That focus means the actives are loaded at a higher percentage than in everyday serums, so the choice of formula matters. This guide maps the 8+ SKUs in the current lineup to the concerns they target and explains how to layer and size them correctly.
What Sets an Ampoule Apart from a Serum
Ampoules are a Korean skincare format that concentrates actives into a smaller, more potent dose than a standard serum. DEMAR3 ampoules follow this convention: the formulas are viscous, active-heavy, and meant to be applied in a single or double-drop layer rather than spread across the whole face in a thick layer. Using too much at once can cause sensitivity, especially with the exfoliating Burning Ampoule stage.
DIEX Citadue 1.6 Burning Ampoule - Exfoliation and Resurfacing
The DIEX Citadue is DEMAR3's chemical-exfoliation entry. Stage 1 at concentration 1.6 is the introductory step for skin new to active exfoliants. It is positioned before a higher-stage follow-up once tolerance is established. It works best on skin that feels rough, has congestion, or shows an uneven texture, and should not be combined with physical scrubs on the same evening.
Etcell Melatonic Ampoule - Tone Correction and Brightening
The Melatonic formula is formulated to interrupt pigmentation formation and even out surface tone. At 70 ml it is the largest single-unit volume in the range, reflecting how brightening work takes consistent daily use over weeks rather than a short treatment burst. Pair it with a mineral SPF in the morning to prevent new UV-triggered pigmentation from forming while the ampoule works overnight.
Signature Alpe Di 36 Ampoule - Hydration and Plumping
Alpe Di 36 sits in the Signature line alongside the anti-aging variant and takes a hydration-first approach. The 36 designation refers to the formula generation. It is suited to dry or dehydrated skin that needs volume and suppleness restored before addressing fine lines. At 30 ml, it fits neatly into a targeted treatment rotation without displacing a full-size moisturizer.
Anti-aging Alpe Di Ampoule - Firmness and Loss of Elasticity
The Anti-aging Alpe Di shares the Alpe Di base but shifts the active emphasis toward firming and structural support. It is aimed at visible loss of contour around the jaw and cheeks and at deepening lines rather than surface texture. It is the natural pairing for the Alpe Di 36 if skin needs both hydration depth and firmness in the same routine step.
Signature Estud Protector 5.2 Pore Ampoule - Pore Minimizing
The Estud Protector 5.2 Pore Ampoule comes in three standalone sizes (30 ml, 50 ml, 170 ml) and a bundle (170 ml + two 50 ml), which makes it the most size-flexible formula in the range. The 5.2 designation relates to its pH calibration for pore-refining work. It is designed for oily and combination skin where enlarged pores are the primary concern, and it is light enough to layer under a non-comedogenic moisturizer.
Choosing the Right Size
DEMAR3 offers 30 ml formats across several lines as trial-ready entries before investing in 50 ml or 170 ml bottles. The 170 ml Estud Protector is a clinic or household-shared volume that brings the per-ml cost down for committed users. The bundle (170 ml + two 50 ml) is a useful structure if one person uses pore care daily and another uses it a few times a week.
Where Ampoules Fit in Your Routine
Apply DEMAR3 ampoules after toner and before moisturizer. If you use a general hydrating serum as well, the ampoule's higher active load should go first on clean skin, followed by the lighter hydrating serum. The Burning Ampoule is an evening-only step; all other formulas can be used morning or evening. Avoid mixing the Burning Ampoule stage with other exfoliating acids on the same night.
Pairing Multiple DEMAR3 Ampoules
Most users work with one DEMAR3 ampoule at a time. If you want to address two concerns, a workable split is exfoliation (Burning) two to three evenings per week and a hydration or brightening formula on the remaining nights. Do not layer two ampoules simultaneously as the combined active concentration can cause irritation, particularly around the eye contour.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does 'Burning Ampoule' mean in the DEMAR3 DIEX Citadue line?
The 'Burning' designation signals that the formula contains chemical exfoliants that create a mild warming or tingling sensation on application. This is expected and is part of how the actives signal they are working on skin texture and surface cell turnover. If the sensation feels sharp or causes visible redness that persists beyond ten minutes, reduce frequency before building back up.
What does Stage 1 mean for the DIEX Citadue 1.6 Burning Ampoule?
Stage 1 is the introductory concentration level in the DIEX Citadue exfoliating system. It is designed for skin that has not yet built tolerance to active exfoliating formulas. Higher stages carry a stronger concentration and are intended as a progression once your skin handles Stage 1 without irritation over several weeks of consistent use.
How often should I apply a DEMAR3 ampoule each week?
Brightening, hydrating, and pore-refining DEMAR3 ampoules can be used daily, morning or evening. The DIEX Citadue Burning Ampoule should start at two to three evenings per week until your skin adapts; daily use is possible for tolerant skin. If you are new to any formula, start every other day for the first two weeks before moving to daily application.
Do I apply the DEMAR3 ampoule before or after my toner?
Apply the ampoule after your toner and before your moisturizer. Toner prepares the skin surface and improves absorption; the ampoule then delivers its actives into a slightly hydrated skin barrier. Follow with moisturizer to seal in the treatment and prevent trans-epidermal water loss.
Can I use sunscreen over a DEMAR3 ampoule in the morning?
Yes, and with the Melatonic brightening formula you should. Actives that address pigmentation are undermined if UV exposure triggers new melanin formation during the day. Apply the ampoule, let it absorb for two to three minutes, then layer your moisturizer and a broad-spectrum SPF 30 or higher on top.
What does the '5.2' refer to in the Signature Estud Protector 5.2 Pore Ampoule name?
The 5.2 designation refers to the formula's pH level. A pH near 5 is close to the skin's natural acid mantle and allows pore-refining actives to work efficiently without disrupting the barrier. It also means the formula is unlikely to cause the dryness or flaking that higher-pH or strongly acid formulas can produce.
What is the difference between the Signature Alpe Di 36 Ampoule and the Anti-aging Alpe Di Ampoule?
Both use the Alpe Di base formula, but the Alpe Di 36 is oriented toward hydration and plumping while the Anti-aging variant shifts the active emphasis toward firming and addressing elasticity loss. If your main concern is dry, flat-feeling skin, the 36 is the starting point. If you are primarily targeting visible sagging or deepening lines, the Anti-aging formula is the more direct choice.
Which DEMAR3 ampoule is best for oily skin with visible pores?
The Signature Estud Protector 5.2 Pore Ampoule is designed specifically for this concern. It is lightweight enough not to feel heavy on oily skin and comes in three standalone sizes (30 ml, 50 ml, 170 ml) plus a bundle, so you can test the 30 ml before moving to the larger formats.
Can I use two different DEMAR3 ampoules on the same evening?
Layering two ampoules simultaneously is not recommended because the combined active load can irritate the skin barrier, particularly around the eye contour area. A better approach is to alternate: use the exfoliating Burning Ampoule two to three evenings per week and a hydrating or pore formula on the other nights.
Is the 170 ml + 50 ml bundle of the Estud Protector a good value?
The bundle (170 ml + two 50 ml bottles) is structured for high-frequency users or for sharing between two people with different usage patterns. One person can use the 170 ml daily while another uses the 50 ml a few times per week. The per-ml cost is lower than buying the sizes separately, making it the most economical entry if you already know the formula works for your skin.
Are DEMAR3 ampoules suitable for sensitive skin?
The Melatonic brightening formula and the Alpe Di hydrating variants are the gentler options in the range. The DIEX Citadue Burning Ampoule and its exfoliating actives are more likely to cause a reaction on sensitive or reactive skin, and should be patch-tested on the inner arm for three to five days before applying to the face.
Where are DEMAR3 ampoules manufactured?
DEMAR3 is a Korean skincare brand and its products are manufactured in South Korea. Korean cosmetics production operates under the K-beauty regulatory framework, which requires ingredient listing compliance and safety testing before products can be sold domestically and exported.
How do I know the DEMAR3 ampoules on skinsli.com are authentic?
Skinsli sources DEMAR3 products through authorized Korean wholesale channels and carries them in their original, unaltered packaging. The product labels and batch codes match what is sold in the Korean domestic market. If you ever receive a product that looks inconsistent with what is shown on the listing, contact support with a photo and the batch code for verification.
How should I store DEMAR3 ampoules to keep them stable?
Store ampoules at room temperature, away from direct sunlight and humidity. The bathroom shelf near the shower is not ideal because repeated temperature and humidity swings degrade actives faster than stable room conditions do. The Melatonic formula, which targets pigmentation, is particularly sensitive to light exposure, so keep it in its original outer box or a closed cabinet.
Why does the Etcell Melatonic Ampoule come in a 70 ml size while others are 30 ml?
Brightening and tone-correction work requires consistent use over a minimum of four to eight weeks before results become visible. The 70 ml size is calibrated so a single bottle covers a full treatment cycle without running out mid-way and breaking the daily application streak. Smaller 30 ml sizes are common for formulas where users may want to trial before committing, but tone-correction is a commitment-use category by design.
