1
🌿 Centella (Cica) 센텔라/시카
“Cica” = Centella asiatica (tiger grass). The go-to soother for sensitive, stressed or breakout-prone skin.
2
🍊 Vitamin C 비타민C
Best in the AM under sunscreen. Pure L-ascorbic acid is potent; derivatives are gentler for sensitive skin.
3
🔗 Peptides 펩타이드
Amino-acid chains that signal skin to look firmer — a gentle anti-ageing route, even for sensitive skin.
4
🌙 Retinol 레티놀
PM only, start low & slow (1–2×/week), always SPF next day. Avoid during pregnancy.
5
🐟 PDRN (Salmon DNA) 연어 DNA
Polydeoxyribonucleotide — the 2026 “salmon DNA” buzz active. Note: topical evidence is emerging; benefits are cosmetic, not the same as clinical injectables.
6
🫚 Ginseng 인삼
A premium hanbang (Korean herbal) hero, central to luxury anti-ageing lines.
7
🌼 Bakuchiol 바쿠치올
A gentler, often better-tolerated alternative to retinol — but data on pregnancy safety is limited.
8
🍀 Madecassoside 마데카소사이드
The most studied active in cica — concentrated soothing & barrier support.
