ISOI Pore Tightening Tonic Essence
Ingredient analysis and how the ad lines read
Read on 2026-09-22
What is this product?
A rose-water toner built around witch hazel, Rhus gall extract and three fruit extracts with glycolic acid, aimed at pore care and smoother skin texture. The plant-fermented ethanol content makes it a poor match for anyone avoiding alcohol or fragrance.
What makes it different?
The combination of 버지니아풍년화잎추출물 and 붉나무충영추출물 with three fruit-derived acids and glycolic acid gives this toner a genuine exfoliating pore-care profile rather than a purely hydrating one. Rosa Damascena Flower Water sits third and Rosa Damascena Flower Oil near the end, matching the rose positioning. The ethanol at position 4 and the fragrance allergens citronellol and geraniol are the main sensitizing watch points. Concentrations and pH are not disclosed, so acid strength has to be judged from placement alone.
