The science
The exfoliating chemistry of this pad is well grounded, and its three acids each carry a distinct evidence base. Salicylic acid, eleventh on the list, is a lipophilic beta-hydroxy acid whose oil solubility lets it penetrate the sebum-filled follicle and loosen the corneocyte plug that starts a comedone; it is a monograph acne active in the US at 0.5 to 2 percent and controlled trials support its reduction of comedones and inflammatory lesions at those levels. Its position here, above betaine and the botanical extracts but below the glycols, is consistent with a Korean cosmetic dose below the US drug range. Gluconolactone, fifth, is the best-studied polyhydroxy acid: a large, slow-penetrating molecule with humectant and antioxidant properties that produces measurable exfoliation and barrier improvement with less stinging and less photosensitivity than glycolic acid in comparative studies, which is why PHAs are the standard recommendation for exfoliating sensitive or rosacea-adjacent skin. Capryloyl salicylic acid, the lipohydroxy acid, has data for a more targeted, cell-by-cell desquamation at low concentrations, typically 0.3 to 1 percent, and for comedone reduction in acne-prone skin; its late position here matches those doses.
The soothing base has weaker but real support. Propolis, second on the list, contains flavonoids such as caffeic acid phenethyl ester with antibacterial activity against Cutibacterium acnes and anti-inflammatory effects in laboratory and small clinical studies, and it is also a well-documented contact allergen, with sensitisation rates in patch-test populations that rise in people exposed to bee products. Tea tree oil's terpinen-4-ol has antibacterial and anti-inflammatory data and a small randomised literature showing benefit in mild acne at five percent gel, far above the trace here; it also oxidises on storage into sensitising hydroperoxides and is a recognised allergen. Madecassoside has clinical support for reducing erythema and supporting repair in leave-on use, and dipotassium glycyrrhizate is a standard topical anti-inflammatory. Neem, turmeric and holy basil extracts have laboratory antimicrobial and antioxidant data without human topical trials at these levels.
Hydrolyzed chitosan, the final ingredient, has film-forming and antimicrobial properties in vitro but no evidence at a trace position. The launch claim of a completed non-comedogenic human test is a standard Korean patch-and-comedogenicity panel, meaningful for the pad's own vehicle but not an efficacy trial. Taken together, a pad whose exfoliation is on firm ground, whose calming is plausible, and whose botanical antibacterials are more allergen than active at their doses.
