Pyunkang Yul's Calming Clear Spot Patch (Slim Care) are hydrocolloid patches blended with Salicylic Acid, Centella Asiatica, and Heartleaf Extract to treat breakouts and soothe irritations. Because of their beveled edges and 0.1mm thickness, these patches are scarcely visible on the skin. This set includes 40 8mm patches and 105 10mm patches. Ingredients: Cellulose Gum, Hydrogenated Poly(C6-20 Olefin), Polyisobutene, Styrene/Isoprene Copolymer, Salicylic Acid, Melaleuca Alternifolia (Tea Tree) Leaf Oil, Houttuynia Cordata Extract, Niacinamide, Centella Titrated Extract Ointment How to use: Cleanse and dry skin at night. Don't apply any skincare to your skin yet. Remove a patch from the film and apply to the problematic area. Follow with your usual skincare routine. Replace the patch as it becomes white due to exudates.
