How to use
- Apply a patch from the Dark Spot AC Patch to clean, dry skin at the end of the evening routine.
- Apply a patch to clean, completely dry skin over the target area. Press gently to help it adhere, leave on as directed on the package, then remove carefully. Avoid applying to irritated or damaged skin.
- Nothing goes over it, and it holds best on bare skin, so put it on after your last leave-on layer has fully absorbed.
- One patch per site per session. Do not press a fresh patch onto damp skin or over a cream; it will lift within the hour.
Does this product contain added fragrance?
No. Neither fragrance nor parfum appears on the ingredient list for CURESYS Dark Spot AC Patch (9pcs ). Those are the two names a cosmetic label uses for an added scent blend, so a formula carrying one would name it. The full list is printed in the Ingredients section of this page.
Are any declarable fragrance allergens listed?
No. None of the 26 fragrance components that EU cosmetic labelling requires to be named individually appear on the ingredient list for CURESYS Dark Spot AC Patch (9pcs ). They are the components most often reported as contact allergens, which is why that rule names them one by one.
Does this product contain denatured or SD alcohol?
No. The ingredient list for CURESYS Dark Spot AC Patch (9pcs ) names no denatured alcohol, SD alcohol or ethanol. Fatty alcohols such as cetyl and cetearyl alcohol are a different class of ingredient, used as emollients and thickeners, and are not counted here.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

12 of 12 explained
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- Arbutin active
- Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two.
- Tranexamic Acid active
- Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired.
- Zingiber Officinale (Ginger) Root Extract plant extract
- Ginger root extract. It carries gingerols, gives a warming sensory character, and is used as an antioxidant-rich herbal extract.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Camellia Sinensis Leaf Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
- 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.
