DIVE-IN Low Molecular Hyaluronic Acid Serum
Torriden
DIVE-IN Low Molecular Hyaluronic Acid Serum
Serum

A beautifully formulated, totally non-tacky hyaluronic acid serum. By utilizing 5 different molecular weights of HA alongside Panthenol and Ceramide NP, it plumps the skin deeply rather than just sitting tightly on the surface. It gets its iconic pastel blue color entirely naturally from Malachite Extract.

Advanced Snail 96 Mucin Power Essence
COSRX
Advanced Snail 96 Mucin Power Essence
Serum

An absolute legendary holy-grail staple across Malaysia that defined the entire global glass-skin trend. COSRX manages to achieve unrivaled cellular repair performance by using a beautifully minimalist 11-ingredient INCI string, dropping plain water entirely to build the formula over a massive **96.3% raw Snail Secretion Filtrate** baseline. Free from added synthetic perfumes, silicones, and drying alcohols, it loads heavy amounts of native mucopolysaccharides, glycolic fractions, and copper peptides past your epidermal reliefs. The physical texture is a highly unique, stringy, gooey clear gel-liquid that stretches beautifully out of the pump, gliding across cells with a rich slippery cushion before absorbing flat within 30 seconds into an incredibly plump, touch-soft mochi skin glow.

โ˜… 8.5
Ceramide Ato Concentrate Cream
Illiyoon
Ceramide Ato Concentrate Cream
Moisturizer

A thick, deeply occlusive cream featuring specialized encapsulated ceramides. It forms a highly protective, semi-matte seal over the skin, making it exceptional for eczema, flaking, and severe winter dryness. However, its heavy texture and stearic acid content may trigger breakouts in oily skin.

Skin Perfecting 2% BHA Liquid Exfoliant
Paula's Choice
Skin Perfecting 2% BHA Liquid Exfoliant
Exfoliant

The global gold standard of BHA exfoliants. It utilizes Methylpropanediol as a brilliant penetration enhancer, allowing the 2% Salicylic Acid to dive deep into the pore lining to dissolve oxidized sebum. It is incredibly effective but can leave a slightly tacky finish on the skin.

Relief Sun : Rice + Probiotics SPF50+ PA++++
Beauty of Joseon
Relief Sun : Rice + Probiotics SPF50+ PA++++
Sunscreen

The viral sensation that redefined modern daily sun defense. Manufactured by Kolmar Korea, it features a highly sophisticated chemical matrix utilizing advanced, stable European filters (Uvinul A Plus, Uvinul T 150, Tinosorb M, Iscotrizinol). It looks and feels exactly like a lightweight, elegant Korean dynamic daytime moisturizer. It dries completely clear with zero ashy white cast. While a dream for dry, normal, or dehydrated skin types, the rich 30% rice base and fermented grain extracts can induce minor congestion or a greasy sheen on hyper-oily skin paths in humid climates.
