COSRX AC Collection Ultimate Spot Cream
What is AC Collection Ultimate Spot Cream actually for?
AC Collection Ultimate Spot Cream is a targeted overnight spot treatment on an aloe leaf water base, with zinc oxide sitting fifth and calamine right after it on this jar's own twenty-four ingredient list, the pair most Korean spot creams lean on to dry down a raised, inflamed-looking area overnight. Scutellaria baicalensis root extract and tea tree leaf oil appear further down the same list, both tied to blemish-prone skin. It reads as a pinpoint treatment for an active spot rather than an all-over moisturizer.
Is this cream suitable for sensitive or reactive skin?
This jar's own list carries no added fragrance, no denatured alcohol, no paraben, no sulfate surfactant, no mineral oil, and no added colourant, a reasonable starting point for skin that reacts to those categories generally. Tea tree leaf oil is on the list, so anyone who knows they react to tea tree specifically should read the full panel on the box first. Because it's built for congestion and active spots rather than the whole face, patch testing a new spot treatment is sensible for reactive skin.
How long before I see a difference on a spot?
Zinc oxide and calamine work by settling and drying the surface of a spot rather than changing it instantly, so most people notice a visible difference over a night or two of use rather than after a single application. Consistent overnight use on the same active spot, rather than occasional dabbing, is how this jar's own list is built to be used. It isn't formulated as a leave-on treatment for the whole face.
Can I use this alongside my regular moisturizer?
Because this is a thick, matte spot treatment rather than a hydrator, most routines apply a regular moisturizer to the face first and then dab this cream only on the specific spot as a final step. Whether it pairs safely with a separate niacinamide or centella serum on the same spot isn't something this jar's own ingredient list can confirm, so patch test any combination first. Keeping it to a small area rather than the full face leaves the rest of a routine unaffected.
How do I know this is the real Korean-market formula?
This jar's own barcode, 8809598450165, is the intact Korean-market code COSRX prints on the box, not a number swapped in for a different retail market. COSRX doesn't outsource authentication to anyone else: it runs its own verification page on cosrx.com, where you enter the batch number and expiration date printed on your specific unit. Reading those two numbers straight off your own box, rather than trusting what a seller states, is the check that actually confirms it.

Ingredient list read from cosrx.com on 18 August 2026.
23 of 24 explained
- Aloe Barbadensis Leaf Water plant extract
- Aloe leaf water, the dilute form of aloe used in place of plain water. It carries some of the leaf polysaccharides and sugars.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- Glycerine humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- Dimethyl Sulfone solvent
- Dimethyl Sulfone is MSM, an organic sulfur compound that dissolves in water. It is used as a conditioning ingredient and as a carrier for other actives.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Polysorbate 60 emulsifier
- Polysorbate 60 is a water-loving emulsifier used with a fatty co-emulsifier to build stable lotions and creams.
- Elaeis Guineensis (Palm) Oil emollient
- Palm Oil is a rich emollient high in palmitic and oleic acids. In skincare it is more often a source material for esters and emulsifiers than an ingredient on its own.
- Elaeis Guineensis (Palm) Kernel Oil emollient
- Palm kernel oil, high in lauric acid and solid at room temperature. It gives balms and cleansing bases their body.
- Cetearyl Olivate emulsifier
- Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
11 more explained
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Calamine absorbent
- Calamine is a mineral blend of zinc oxide with a trace of iron oxide, which is where its pale pink colour comes from. In a formula it is an absorbent mineral powder.
- Dimethicone silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- Illicium Verum (Anise) Fruit Extract plant extract
- Star Anise Fruit Extract carries aromatic plant compounds. It is used as a conditioning extract and contributes scent.
- Scutellaria Baicalensis Root Extract plant extract
- Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
- Xanthan gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Melaleuca Alternifolia (Tea Tree) Leaf Oil fragrance component
- Tea Tree Leaf Oil is an essential oil from an Australian shrub, carrying terpinen-4-ol. Korean formulas use it in products aimed at blemish-prone skin; it is potent, aromatic, and one of the essential oils most likely to bother reactive skin.
- Ethyl Hexanediol humectant
- Ethyl Hexanediol is a glycol that hydrates and makes a formula less hospitable to microbes, the same double role 1,2-hexanediol plays.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Asiatic acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- Madecassic acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.

How it works
A spot cream is a targeted step: it goes on one place rather than across the face, which is why it can carry things a full-face cream would not. This one is built on aloe barbadensis leaf water with zinc oxide and calamine, the pair that dries down on the surface, and tea tree leaf oil and scutellaria baicalensis root extract behind them. It goes on last in the evening, dabbed onto the spot once everything else has absorbed. It is not a moisturizer and it is not meant to be spread out across the cheeks. One dab per spot, overnight, on the nights you want it.
How to use
- Use the AC Collection Ultimate Spot Cream last in the evening, on clean skin, after every other layer has absorbed.
- A small dab straight onto the spot, kept to the spot itself rather than spread over the skin around it.
- Nothing goes over it, and it stays on overnight.
- On the nights you want it. Do not use it across the whole face; it is built for one place at a time.

Pretty much every step of a Korean skin care routine is going to have some component of hydration.
Alok Vij, MDDermatologist, Cleveland Clinic I think it's fair to say I've seen lots of patients use tea tree oil for a variety of skin issues. It's a natural remedy that is known to help.
