What Is SKIN1004 Azelaic Acid 10 Ampoule?

SKIN1004 Azelaic Acid 10 Ampoule is a 30ml leave-on ampoule sold through the brand's direct store for USD 20.40, checked 2026-10-06, and built on what the brand calls a 3X Azelaic Active Formula: Azelaic Acid 10% layered with two further derivatives, Potassium Azeloyl Diglycinate and Azelamide MEA. The question of what this product is settles on one axis in the azelaic-acid category: which supporting ingredients actually sit behind a headline acid percentage, since a 10% label alone says nothing about the base, the texture, or what else travels with it in the bottle. SKIN1004's own product page answers that in full, publishing a complete, 27-item INCI list that names the acid complex alongside a documented set of supporting ingredients, in a water-based liquid ampoule, not a cream or a gel formula. A 9ml size exists for testing the formula before committing to the full 30ml bottle.

SKIN1004 Azelaic Acid 10 Ampoule 30ml

SKIN1004 Azelaic Acid 10 Ampoule 30ml comes alongside a 9ml size, and the brand lists both as the acido azelaico skin1004 formula on its own product page, where the 3X Azelaic Active Formula is broken out into three labeled figures: Azelaic Acid 10%, Potassium Azeloyl Diglycinate 1%, and Azelamide MEA 0.5%, for an 11.5% combined complex.

That complex sits inside a full ingredient list of 27 entries, led by Water and Azelaic Acid and continuing through a named set of supporting ingredients, including Centella Asiatica Extract; the complete roster is published in full on the product's own page, not condensed into a marketing summary.

For a reader who wants to know precisely what sits inside a 10% azelaic-acid ampoule before buying one, SKIN1004 Azelaic Acid 10 Ampoule settles the question with that complete, 27-item ingredient list published directly on its own product page, instead of a short claims paragraph.

• The liquid, water-based ampoule format lets the acid complex absorb as a single serum step.
• Potassium Azeloyl Diglycinate and Azelamide MEA are layered onto the 10% free acid in the same bottle, for an 11.5% combined complex.
• Centella Asiatica Extract sits on the same ingredient list as the acid complex itself.
• The 9ml size allows testing the formula before committing to the 30ml bottle.

Outside its own store the ampoule also reaches shoppers through Superdrug in the UK and through Song of Skin in the US and Canada.

Because the formula publishes its full complex and its complete supporting-ingredient list on one page, SKIN1004 Azelaic Acid 10 Ampoule gives a direct answer to what the product is: a liquid, 10% free-acid azelaic ampoule with two further labeled derivatives and a named set of supporting ingredients, sold in two sizes from the brand's own store and a small set of named retailers.

Three other 10% azelaic-acid treatments sit on the same comparison shelf. The Ordinary's Azelaic Acid Suspension 10% is a cream-gel suspension in a silicone-dominant base, listing Dimethicone and Polysilicone-11, sold in 30ml and 100ml sizes through its own regional stores and retailers such as Sephora and Beauty Bay. Paula's Choice's 10% Azelaic Acid Booster is a 30ml cream-gel booster, listing Salicylic Acid 0.5% and Licorice Root Extract, sold through Dermstore, Sephora and Cult Beauty. Naturium's Azelaic Topical Acid 10%, titled Azelaic Acid Derivative Complex 10% on its current official page, lists Potassium Azeloyl Diglycinate rather than free azelaic acid as its active ingredient, alongside Niacinamide and Ethyl Ascorbic Acid, in a 1 fl oz bottle with a 2 fl oz jumbo size at Target. SKIN1004's own 3X Azelaic Active Formula states each derivative separately, Azelaic Acid 10%, Potassium Azeloyl Diglycinate 1% and Azelamide MEA 0.5% for an 11.5% combined complex, a breakdown mirrored on independent databases such as Skincarisma and tied to a company-level listing for its parent, Craver Corp., on the PETA Beauty Without Bunnies registry. That same ampoule uses a water-based liquid base, Water as its first INCI entry, so the complex sits dissolved rather than suspended in both the 30ml bottle and the 9ml size.

How to Layer It Into a Skincare Routine

A liquid ampoule step like this one is designed to go on cleansed skin, after a toner and before a moisturizer or sunscreen, following the general order leave-on actives use in a layered routine: thinnest, most water-like steps first, richer or more occlusive steps last. SKIN1004 Azelaic Acid 10 Ampoule's water-based texture places it early in that sequence, ahead of a cream or an oil-based sunscreen.

Both the 30ml bottle and the 9ml size apply the same way, a small amount smoothed over the face before the next step; the only variable is how long a bottle lasts before it needs replacing. Because the full ingredient list is published on the brand's own page from the first entry to the last, a reader layering it with other acids or actives can check the complete order against that list instead of guessing from the front-of-pack percentage alone.

A full ingredient list published down to its last entry also lets a reader cross-check potential interactions before adding new products to a routine: because SKIN1004 states all 27 positions on one page, nothing in the formula is held back as an unlisted proprietary blend, which matters most for anyone already using other active treatments alongside it.

That full-list transparency, three labeled active figures plus a complete supporting-ingredient roster, is what documents SKIN1004 Azelaic Acid 10 Ampoule as a fully disclosed 10% azelaic-acid formula.
