AMPLE:N - Korean «Dermo-Ampoulism» by Coreana Cosmetics (30 years of R&D)

AMPLE:N is a Korean cosmeceutical brand launched by Coreana Cosmetics - one of South Korea's oldest cosmetics groups, founded at the late 1980s. Its name sums up the founding concept: « Bulb + N (= and) »the brand specializes exclusively in high-concentration ampoule format, with a philosophy called« Dermo-Ampoulism »The aim is to scientifically prescribe cosmetic active ingredients in concentrated ampoule form, just as a dermatological laboratory would. All products are manufactured 100% in Korea with patented ingredients and systematic clinical testing.

The Shot Ampoule range is built around a modular logic: one ampoule for each skin problem, which can be combined according to need. Best-sellers include Ceramide Shot Ampoule (barrier repair), the Peptide Shot Ampoule (anti-aging), Hyaluron Shot Ampoule (hydration), and Centel Calming Shot Ampoule (redness). The brand is distributed mainly via online K-beauty channels (YesStyle, StyleVana, Amazon) and has been available in France for some years, with a strong presence on the Reddit skincare and BeautyDecoded communities.

Cerafull Complex™ 50,000 ppm - formulatory deciphering

Cerafull Complex™ is AMPLE:N's patented active ingredient for Ceramide Shot Ampoule. It is formulated with 50,000 ppm (5% formula) - a significant concentration for an expensive lipid active ingredient. Its composition reproduces the three essential elements of natural intercellular cement of the stratum corneum (Elias PM, J Invest Dermatol, 2005):

In addition to ceramides, the formula incorporates complementary, clinically relevant active ingredients: niacinamide (anti-inflammatory, barrier-enhancing, sebum-regulating), beta-glucan (skin immunomodulator, healing), adenosine (anti-wrinkle active ingredient regulated in South Korea), allantoine (soothing), and patented arctigenin (forsythia extract - complementary barrier reinforcement). The formula excludes fragrance, alcohol, silicones, mineral oils and colorants.

«AMPLE:N interests me for a central clinical reason: Ceramide Shot Ampoule reproduces the 3 essential ceramides + cholesterol + sterols at 50,000 ppm - this is the theoretical optimal composition of a barrier repairer according to the literature (Elias, 2005). BeautyDecoded data confirm this consistency: dry skin 90.3, sensitive skin 0, redness 51. But the opinions are clinically honest: it doesn't replace a cream for very dry skin (several opinions of tightness), it feels fluffy on certain profiles, it dilates pores on one case. These are not flaws - they are the normal limits of a light aqueous-lipidic ampoule. This product should be covered with an occlusive-emollient cream for very dry skin. Exceptional signal in Peptide Shot: one user used the BeautyDecoded app in real time to understand her skin reaction - that's exactly what it's for.»

Note on BeautyDecoded reviews: the ratings and review excerpts displayed on this page come from users of the BeautyDecoded application. These reviews are not verified. Publication dates and review details are available on each product sheet.

Unique signal: the two AMPLE:N ampoules are designed for opposite profiles. Ceramide Shot (dry skin 90.3, sensitive skin 0, fragrance-free) is the universal barrier treatment. Peptide Shot (oily skin 91, sensitive -3.35, fragranced) targets non-sensitive oily to combination skin. When combining the two on the same skin, it's important to check the fragrance tolerance of Peptide Shot.

BeautyDecoded algorithmic scores

Verdict Sensitivity (Dr David rule) : Suitable for sensitive skin  (score : 0)

Expert deciphering

AMPLE:N flagship ampoule - concentrated serum for the skin barrier. Dry skin score: 90.3 and normal to dry skin score: 90.3 - excellent. Oily skin score: 56 - moderate. Sensitive skin score: 0 - well adapted, consistent with the absence of fragrance, alcohol and essential oils. Redness score: 51 - relevant for a barrier repair product. Score 4,149/5 out of 47 BeautyDecoded reviews - the most documented product of the AMPLE:N brand in the database, with one of the highest volumes of reviews among the marques K-beauty niche.

Cerafull Complex™ at 50,000 ppm (5% in the formula) reproduces the three essential ceramides of the stratum corneum (ceramide 1 - fatty-omega acid, ceramide 2 - non-hydroxy fatty acid, ceramide 3 - phytosphingosine) combined with cholesterol and plant sterols from rapeseed. This lipid architecture mimics the skin's natural intercellular cement (Elias PM, J Invest Dermatol, 2005). Patented arctigenin (extracted from forsythia suspensa) reinforces the barrier via a complementary mechanism. Niacinamide (INCI position 8) and beta-glucan provide complementary anti-inflammatory and moisturizing properties. Redness score 51: consistent with this anti-inflammatory profile.

The 52 BeautyDecoded reviews constitute the brand's richest documentary database, and reveal a very precise usage profile. Consensus strengths: strong loyalty («it's the one I repurchase the most»), light texture and practical pipette, pre-retinol use («I apply it before my retinol in the evening»). Documented points of vigilance: insufficient for very dry skin (3 reviews), linting reported, pore dilation on a specific profile, «nourishing but not magical». A very specific comparative review compares this product to SkinCeuticals Triple Lipid Restore, positioning AMPLE:N as «gentler, more affordable, daily use.»

BeautyDecoded user reviews (47 reviews in total)

Peptide Shot Ampoule - Anti-Aging For Discerning Profiles

4.67/5  - 3 reviews BeautyDecoded | Price : ~20-30 € / 100 ml

Main assets : Tri-peptide complex + anti-aging active ingredients + fragrance (signal)

BeautyDecoded algorithmic scores

Verdict Sensitivity (Dr David rule) : Not suitable for sensitive skin  (score: -3.35)

Expert deciphering

Anti-aging ampoule with peptide complex. Oily skin score: 84 and normal to oily skin score: 91 - optimal profile. Dry skin score: 32.2 - unsuitable. Sensitive skin score: -3.35 - unsuitable, probably due to fragrance and/or concentrated active ingredients. Anti-aging score: 74.8 - high for a K-beauty ampoule. Blemish score: 72.25 - very relevant. Score 4,667/5 out of 3 reviews.

Peptide Shot Ampoule targets the signs of ageing via a complex of tri-peptides (probably palmitoyl tripeptide-1, palmitoyl tetrapeptide-7 or matrikines analogues). Signaling peptides stimulate collagen and elastin synthesis in dermal fibroblasts. Anti-aging score 74.8: high, consistent with an active peptide complex. Age spot score 72.25: may contain depigmenting active ingredients such as niacinamide or tranexamic acid. Sensitive skin score -3.35: indicates the presence of a fragrance - confirmed by a BeautyDecoded review.

The 3 BeautyDecoded reviews are clinically very revealing. An exceptional review: a user felt warmth and tingling on application, went to the BeautyDecoded app, read the composition and realized that the product was not suitable for her sensitive skin - «I was influenced.» This signal is unique in the BeautyDecoded database: it's the first time a user has explicitly documented the use of the app as a post-cutaneous reaction decision tool. The second review is very positive (redemption), while the third confirms a lightly scented but pleasant texture.

My analysis

«Peptide Shot Ampoule is AMPLE:N's anti-aging ampoule - anti-aging 74.8, spots 72.25, oily skin 91. Rating 4,667/5 out of 3 reviews. Critical signal: sensitive skin -3.35 confirmed by a review documenting tingling and recourse to BeautyDecoded for diagnosis. This product is suitable for normal to oily skin that is not sensitive to fragrances. Dry skin 32.2: unsuitable. 3 insufficient reviews.»

Verdict: Anti-ageing K-beauty - Rating 4,667/5 out of 3 reviews. Anti-ageing 74.8, blemishes 72.25. Oily skin 91. Fragrance signal: -3.35, documented tingling. Dry skin 32.2. 3 insufficient reviews.

BeautyDecoded user reviews (3 reviews in total)

4.7/5  «Intriguing serum - at first it felt strange to use this serum because of its texture. It's effective, leaves the skin beautiful, has a subtle fragrance and the skin doesn't feel tight. I repurchase it often.»

4.7/5  «Thank you BeautyDecoded - I started using this product and very quickly began to feel warm and tingly. So I went to your application and I understood why: the composition is not at all adapted to a sensitive skin like mine. I was influenced.»

4.7/5  «Very pleasant - I really like this product, which I use every night. It's lightly scented and leaves my skin feeling soft.»

Ceramide Shot Ampoule as a pre-retinol treatment - the documented sandwich method

Several BeautyDecoded reviews document expert use of Ceramide Shot Ampoule: application before retinol as a protective layer. This technique, known as «retinol sandwich» or «buffering», is a dermatological practice documented to reduce retinoid irritation.

This type of use - documented spontaneously by several BeautyDecoded users - confirms that Ceramide Shot Ampoule has become an advanced routine tool, beyond its «simple dry barrier» positioning. Its 0 sensitive skin score and fragrance-free formula make it perfectly compatible with retinoid routines.

AMPLE:N Ceramide Shot vs alternatives - positioning in ceramide serums

AMPLE:N Ceramide Shot is positioned as the’the most formulatively complete light ceramide ampoule (3 ceramides + cholesterol + sterols) at an affordable K-beauty price. Vs SkinCeuticals Triple Lipid: 14x less expensive, better tolerated (HE-free), lighter. Vs CeraVe: more concentrated in ceramides, less occlusive - complementary rather than competitive. For very dry skin requiring occlusion: CeraVe or Aquaphor Eucerin as a top coat over Ceramide Shot.

Frequently asked questions - AMPLE:N

Is AMPLE:N a good brand?

AMPLE:N is a serious Korean cosmeceutical brand, a subsidiary of Coreana Cosmetics (over 30 years of R&D). Its «Dermo-Ampoulism» philosophy - concentrated active ingredients in ampoule format with clinical tests - is consistent and well-documented. BeautyDecoded references 2 products with 55 reviews. Ceramide Shot Ampoule (47 reviews, 4.149/5) is one of the most well-documented ceramide serums in the database. Its main limitation: a narrow range (2 products referenced in BeautyDecoded) and a price slightly higher than some comparable K-beauty products for formulation quality.

Is Ceramide Shot Ampoule suitable for all skin types?

Just about. The sensitive skin score is 0 (well adapted) - fragrance-free, alcohol-free, colorant-free, mineral oil-free. Dry skin score is 90.3 (excellent). The oily skin score is 56 (moderate). However, the 47 BeautyDecoded reviews reveal two major limitations: it is insufficient on its own for very dry skin (several reports of post-application tightness), and it feels fluffy on certain profiles. These signals confirm that it should be covered with an occlusive-emollient cream (CeraVe, Aquaphor) for very dry skin, and applied to slightly damp skin.

What's the difference between Ceramide Shot and Peptide Shot AMPLE:N?

The two ampoules are formulatively complementary but target opposite profiles. Ceramide Shot (dry skin 90.3, sensitive skin 0, fragrance-free) targets barrier repair and hydration of dry to normal skin - suitable for sensitive skin. Peptide Shot (oily skin 91, sensitive skin -3.35, lightly fragranced, anti-aging 74.8) targets anti-aging on normal to oily skin - not recommended for skin hyper-reactive to fragrances. A BeautyDecoded review explicitly documents a cutaneous reaction to Peptide Shot on sensitive skin.

How to use Ceramide Shot Ampoule AMPLE:N?

After cleansing and toning, apply 4-5 drops to the palm, warm briefly and pat onto the face until absorbed. Cover with moisturizer (mandatory for dry skin). Two expert uses are documented in BeautyDecoded reviews: as a pre-retinol (sandwich technique - protective layer before retinol to reduce irritation) and as a night treatment for very dry areas of the body (hands, feet). The bottle's pipette is praised for its precise dosage.

Where can I buy AMPLE:N in France?

AMPLE:N is not distributed in French pharmacies. Available points of purchase are: YesStyle, StyleVana, StyleKorean, Amazon.fr (official Coreana EU seller), and specialist K-beauty sites (Koreabe, BeautyComet). The 100ml format at ~18-28 € is the most common. Jumbo (200ml) and mini (30ml) sizes are available from different retailers. Check the seller's authenticity - counterfeits are possible on non-approved marketplaces.
