Specially designed for large-area inflamed acne, cystic acne, clustered acne and body acne, this product adopts enlarged square size that fully covers large breakout areas, avoiding the incomplete coverage and edge leakage of common small round patches. The core thickened high-absorption hydrocolloid material has more than twice the absorption capacity of ordinary acne patches, which can fully absorb secretions and interstitial fluid from deep cystic acne. Meanwhile, it forms an airtight protective layer on the skin surface to isolate external bacterial irritation, reduce inflammation and redness, and accelerate deep acne healing. With gradient edge pressing technology, it fits tightly even on large areas, not easy to curl or fall off, and is waterproof and sweat-resistant. Drug-free, gentle and non-irritating, it can be used not only for large facial breakouts but also for acne on chest, back and other body parts, making it a must-have care product for severe acne-prone skin.
