Adenosine 0.04%: Functional Ingredients and Product Testing in 3F Ampoule

NARINFLA 3F Ampoule’s three growth factors are EGF, FGF, and IGF, with the brand-confirmed 11 peptides. Combining several ingredients is a concrete feature of the composition. Ingredient count does not establish greater effects than another product or identical action in every skin layer. Ingredient presence and comparative efficacy are separate claims.^[S6]

3F Ampoule is a dual-functional brightening/wrinkle-care cosmetic in Korea. “Dual” identifies two functions, not twice the wrinkle effect. Everyday use of the whole formula and the evidence underlying Korean functional-cosmetic regulation should be considered separately. Seeing the names of three growth factors does not make those names the notified Korean wrinkle-care ingredients.^[S1][S6]

Page 1 of the brand-held stamped document is a report for a functional-cosmetic item exempt from individual review. It names NARINFLA Lifting Booster Ampoule and lists notified standards and test methods as niacinamide, adenosine, liquid preparation. The report date is September 3, 2024. Page 3 lists niacinamide 2.0g and adenosine 0.04g per 100g of finished product: reported levels of 2.0% and 0.04%, respectively. Do not read the filename 260818 as the report date or present these filing quantities as measured concentrations of a currently sold batch.^[S8]

Finished-product evidence makes actual use conditions more assessable than ingredient names alone. Participant ages, assessed areas, and two- and four-week time points help you judge relevance to your question. Connecting those details with a comfortable moisturizer and product directions is a practical selection process, not a competition for the largest ingredient percentage.

Section 3 of official Annex 4 lists ingredient levels for products that help improve skin wrinkle appearance. Adenosine is listed at 0.04%; retinol, retinyl palmitate, and polyethoxylated retinamide have their own standards. Their figures and units are not all identical, so the numerical size alone cannot rank the ingredients.^[S1]

0.04% is not the percentage of wrinkle reduction after application, an absorption rate, a collagen increase, or a satisfaction rate. Keep it in the category of ingredient content. Putting it beside study improvement rates as though comparable mixes different information.

The annex is titled categories of functional cosmetics for which data submission is omitted. Permitted formulations are also limited to lotions, liquid preparations, creams, solid preparations, and impregnated masks, with efficacy and application conditions. Matching an ingredient name and concentration alone does not automatically grant any product the same status.^[S1][S2]

Feeling that 0.04% sounds small differs from recognizing it as a functional-cosmetic standard. The annex does not provide a dose-response formula promising proportionally larger results from more application or a higher concentration. Separate standards from effect magnitude.

Annex 4 limits the claim to “helps improve skin wrinkle appearance.” The helping scope matters. Statements that deep wrinkles disappear, facial structure changes, or the product replaces procedures exceed that wording.^[S1]

Functional status does not guarantee the same result for every skin condition and wrinkle. Suitability and individual experience are separate. An eye-area result cannot be relabeled as another area’s result, and a study duration does not promise everyone a noticeable change by that deadline.

“Dual-functional brightening and wrinkle care” identifies two permitted functions. It does not mean twice the wrinkle benefit of a single-functional product. Nor do dual-functional status and completion of a separate irritation test prove one another.

Functional labeling is useful, but do not finish your decision at a number. Check the current container’s functional statement and directions; if an additional effect percentage appears, read the supporting study separately. This practical reading order keeps functional scope and research findings distinct.

The product report’s adenosine filing level of 0.04% can be read alongside the same level in the notified annex. Niacinamide 2.0% and adenosine 0.04% together in the filed liquid preparation make the Korean 3F brightening/wrinkle-care description more specific. The report is not a complete formula or an efficacy-rate study. Do not infer Centella content or growth-factor/peptide presence or quantities from the table for these two functional ingredients.^[S8][S1]

Annex 4 lists categories exempt from data submission, including ingredient levels, formulation types, and claim conditions. The MFDS Q&A below describes reporting when the functional ingredient types, levels, standards, and test methods match the notified requirements. Exemption from some data submission does not mean no quality standards or administrative procedures.^[S1][S3]

The MFDS response dated March 9, 2026 addresses reporting a cream with adenosine 0.04%, niacinamide 2%, and alpha-bisabolol 0.5%. It explains that functional ingredient types, quantities, specifications, and test methods must match the notified items.^[S3]

In that question, use of two ingredients with the same brightening function meant the product needed functional-cosmetic review. Do not extend this to “any combination of ingredients with different functions cannot be reported.” The question’s conditions matter.^[S3]

A product differing from notified requirements is not thereby illegal or ineffective. Consider an individual-review route and the required evidence. Checking actual product labeling and relevant documents is more accurate than inferring the review/reporting route from concentrations alone.

Abella’s 2006 study compared an adenosine cream, a dissolving film, and placebo for eye-area and glabellar wrinkles. The abstract describes 126 women aged 45–65, with two of three products assigned to opposite eye areas. Each product had 84 participants, and 84 participants also met the glabellar criteria.^[S4]

Products were used twice daily for two months, with FOITS skin-surface assessments at weeks 0, 3, and 8. Significant improvements in eye-area smoothness were reported for both adenosine formulations, and glabellar wrinkle measures improved with the cream. Keep the formulation and measurement method alongside any explanation.^[S4]

Only the full PubMed abstract was directly checked, not the paid full paper. The abstract does not identify whether the concentration matched Korea’s 0.04% standard. We therefore do not say the research proved 0.04% efficacy or turn its three-week time point into a universal timeline for wrinkle ampoules.

Placebo control and randomization are important design details, but the products studied were not NARINFLA 3F Ampoule. Keep a reason to research adenosine-containing products separate from our finished-product figures so a source does not support more than it establishes.

The eye-area assessment used skin-surface profile measures Ra and Rz. The abstract reports significant smoothing after three weeks, followed through eight weeks, for both formulations. This is positive human evidence for products containing the ingredient, but no specific improvement percentage or adenosine concentration appears in the abstract. We do not fill in missing numbers and distinguish eye area from glabella and cream from film.^[S4]

PROBEM Skin Clinical Research Center conducted Korean study PM-23A29-WR008 in 2023. Twenty participants, mean age 50, used the product morning and evening for four weeks, with eye-area, nasolabial, and neck measurements by Antera3D. The public official explanation identifies the participants as 20 women.^[S5]

The rounded four-week mean improvement rates were 18.5% for the eye area, 13.7% for nasolabial wrinkles, and 15.5% for neck wrinkles. These mean percentages describe changes in the respective instrument measures from baseline—not a percentage of visible change or a uniform reduction in total facial wrinkles.^[S5]

This finished-product study used a within-group comparison without a control. It observed the formula, multiple ingredients, and moisturizing effects together, not comparison with an otherwise identical product lacking adenosine. Saying “0.04% adenosine caused 18.5% improvement” exceeds the design’s scope.

Individual maxima differ from means. When an advertisement emphasizes a maximum, check that it is a maximum among 20 people alongside the overall mean, institution, and duration. This article uses mean values only and does not include results from a different China-market formula as Korean-product findings.^[S5]

Current official NJ26 also gives two-week means of 6.6% for the eye area, 7.5% for nasolabial wrinkles, and 8.7% for the neck. Larger observed four-week means help explain duration, but do not establish continued proportional improvement or promise a change to everyone at four weeks. Keep the study’s “appropriate amount” distinct from current guidance of 2–3 drops; the study did not validate a drop count.^[S5]

Neither the regulation nor the cited research establishes a basis for substantially increasing application to obtain faster change. Twice-daily research use explains how a study was run, not a prescription of the same amount and frequency for every individual. Consider directions together with your response.

Changing an ampoule, retinol, and exfoliant simultaneously makes the source of discomfort hard to identify. We suggest adding one product at a time and briefly recording date, amount, and skin response. This is practical suitability observation, not a clinical efficacy test.

AAD describes testing a new product on a small inner-arm or inner-elbow area twice daily for 7–10 days, using the usual amount and thickness. Wash-off products follow their instructed contact time. Washing off and discontinuing after a reaction is central to the guidance.^[S7]

A reaction-free small-area test does not guarantee no reaction during all later use. Severe or persistent symptoms may require qualified local medical care. For use immediately after a procedure or on a wound, ask your treating clinician rather than decide from this wrinkle-functional explanation.^[S7]
