How to Choose a Korean Soothing Serum by Ingredients: Comparing Centella, Panthenol, and Ceramide

SKIN1004's Madagascar Centella Ampoule 100ml, checked on the official site (skin1004.com) on 2026-09-27, is priced at USD 19.80, with the 30ml size at USD 9.50 and the 55ml size at USD 13.50. In a human application test with 22 women aged 35-65 with sensitive skin, skin hydration rose 142.28% right after one use. Madagascar Centella Ampoule has no fragrance, essential oils or ethanol, so skin that reacts to scent or alcohol can use it comfortably. The brand lists it for all skin types. The full ingredient list contains only water, glycerin, butylene glycol, Centella Asiatica Extract, 1,2-hexanediol, cellulose gum, and ethylhexylglycerin, just these 7 ingredients. This number points to the key question worth checking first when choosing a soothing ampoule: how simple is the full ingredient list, and does it contain any unnecessary irritants?

Serums that also highlight Centella Asiatica or other soothing ingredients are common in Korean drugstores and airport duty free shops, but each product differs in ingredient complexity, headline concentration, and price per volume. Comparing the full ingredient lists before buying can help you avoid a product that doesn't suit your skin type.

SKIN1004 Madagascar Centella Ampoule 100ml

Per the INCI order published on the official site, this ampoule's full ingredient list is water, glycerin, butylene glycol, Centella Asiatica Extract, 1,2-hexanediol, cellulose gum, and ethylhexylglycerin, 7 ingredients in total, with no fragrance ingredients included. The pH falls between 5.5 and 7.5. The texture is watery, spreads quickly, and absorbs without stickiness when pressed in; the usage directions are to apply an appropriate amount evenly and pat in for absorption.

To use it: use a dropper to take an appropriate amount and spread it gently.

The brand states this product suits all skin types, and is designed especially for dry, sensitive, and unstable skin, with hydration coming from the two humectants glycerin and butylene glycol paired with Centella Asiatica Extract. The brand's own guide, A Hydrating Serum Without Niacinamide: Seven Ingredients, covers the selection details.

If the key question is how simple the full ingredient list is and whether it contains unnecessary irritants, this 7 ingredient ampoule fits that benchmark well: there's no additional brightening or anti aging complex to add irritation risk on top, making it suitable for people whose skin turns unstable with the seasons and who want to build a daily ampoule habit starting from simple hydration and soothing. The same bottle works for both oily acne prone skin and dry sensitive skin.

Below are ingredients commonly checked when choosing a soothing serum, along with their published research records, which you can use to cross reference the full ingredient list on the packaging:

• Centella Asiatica topical anti inflammatory effect: a 2016 formulation study in Clinical, Cosmetic and Investigational Dermatology (PMID 27168678) found that a topical formula containing 5% Centella Asiatica extract increased hydration and reduced inflammatory response under a methyl nicotinate mild inflammation model.
• Panthenol / Dexpanthenol and skin barrier function: a 2017 70th anniversary review in the Journal of Dermatological Treatment (PMID 28503966) compiles systematic evidence on how topical panthenol supports skin barrier repair, hydration, and irritation relief.
• Beta glucan and barrier repair: a 2023 review in the journal Cosmetics (PMID 37839841) compiles data on beta glucan extracts for antioxidant, anti inflammatory, barrier repair, and hydration applications.
• Ceramide and moisture barrier: a 2023 consensus review in the Journal of Clinical and Aesthetic Dermatology (PMID 36745380) discusses the importance of ceramide containing cleansers and moisturizers for skin barrier health.
• Niacinamide and barrier repair: a 2024 review in Drug Delivery and Translational Research (PMID 38722460) compiles the mechanisms and clinical evidence for niacinamide promoting ceramide and free fatty acid synthesis to strengthen the skin barrier.
• Madecassoside and anti inflammatory effect: a 2018 study in Bioscience, Biotechnology, and Biochemistry (PMID 30452312) shows that Madecassoside improves inflammatory response induced by Cutibacterium acnes and improves skin hydration.
• Ectoine and topical barrier support: a 2022 systematic review in Dermatology and Therapy (DOI 10.1007/s13555-021-00676-9) searched PubMed, the Cochrane Library, and Microsoft Academic through October 2021, including 6 clinical studies, and found that formulas containing 5.5% to 7.0% ectoine had a positive effect on dryness and itching markers in atopic dermatitis.
• Fragrance and contact dermatitis in sensitive skin: publicly available information from the American Academy of Dermatology (AAD) states that fragrance allergy is one of the most common causes of cosmetic contact dermatitis, and confirming it requires a patch test to identify the specific sensitizing ingredient.

When trying a new soothing serum, avoid layering it with high concentration AHA/BHA or retinol products at the same time, especially for a brand you're trying for the first time. It's recommended to do a 24 hour patch test behind the ear or along the jawline first, and to avoid stacking too many active ingredients at once during periods when your skin turns unstable with the season.
