1
A gentle conditioning agent found in soothing Korean 'cica' and post-acne formulas. It is also one of the compounds naturally present in snail secretion filtrate, which is part of why the two show up together.
2
Nature Republic's aloe gel turned a pharmacy staple into a global souvenir. As an ingredient it is mostly water and polysaccharides — genuinely soothing after sun, not a treatment product.
3
Amino acids do double duty in Korean routines: as humectants in essences, and as the basis of the low-pH amino-acid cleansers that replaced squeaky foaming washes.
4
Like birch sap, bamboo water is used as a lighter-feeling base. It shows up most in gel textures aimed at Korea's humid summers, where anything richer feels unbearable.
5
Round Lab built a hero line on it. Substituting a botanical sap for plain water is partly formulation, partly storytelling — the appeal is the light, clean feel rather than any single dramatic active.
6
Skin's barrier is roughly ceramides, cholesterol and free fatty acids together. That is why barrier creams list all three — supplying only one of the trio is a bit like restocking a pantry with nothing but flour.
7
Originally identified in micro-organisms that survive in salt flats and other extreme environments. In skincare it is used as a protective humectant, and it has become a fixture in the recent wave of Korean barrier serums.
8
작약 (jakyak), peony root, is one of the four herbs in the classic 사물탕 (samultang) tonic that Korean luxury brands quote constantly. It brings antioxidant and comforting compounds, and it earns its place in soothing formulas — though as with most hanbang botanicals, the lineage is far better documented than the clinical effect.
