Cocamidopropyl Betaine

★ 9.4

The absolute legendary pioneer of low-pH skin washing across Malaysia and Southeast Asia. COSRX completely dismantled old-school high-pH alkaline cleansing loops by launching this physiological pH 5.5 wash. It utilizes an ultra-mild, non-stripping anionic-amphoteric surfactant matrix (Sodium Lauroyl Methyl Isethionate and Cocamidopropyl Betaine) to lift surface dirt softly. It leaves the critical moisture lipid bricks completely untouched. Packed with **0.5% Styrax Japonicus botanical extract** and natural **Tea Tree Oil**, it targets acne bacteria corridors during washing, rinsing away to leave a thoroughly clean, perfectly balanced fresh satin baseline.

A cult-classic physical bar soap that elegantly dodges the severe alkaline damage of traditional bars. By utilizing Cocamidopropyl Betaine (a gentle liquid surfactant) in a solid matrix, it achieves a low pH that respects the acid mantle. The activated charcoal acts as an incredible physical sponge for heavy midday sebum, while the high dosage of raw honey and glycerin ensures the skin is conditioned during the wash phase.

An incredibly gentle, sulfate-free gel cleanser. Unlike the Foam or Deep Cleansing versions in the Aiken line, this formula entirely bypasses alkaline soaps. It relies on extremely mild amino-acid surfactants (Sodium Cocoyl Glycinate) and a massive Glycerin base to melt away surface impurities without stripping the delicate acid mantle. It is the absolute optimal choice for broken or compromised barriers.

★ 8.2

A highly purifying, saponified cream-to-foam cleanser upgraded with a modern brightening complex. It utilizes a heavy matrix of Myristic, Stearic, and Lauric acids neutralized by Potassium Hydroxide to create a massive, shaving-cream style lather that obliterates heavy oils. It features Niacinamide, Salicylic Acid, and Ascorbyl Glucoside to brighten the complexion and clear congestion during the wash phase. While excellent for robust, hyper-oily skin, the alkaline pH will temporarily breach delicate acidic moisture mantles.

★ 8.8

A meticulously formulated purifying wash that refuses to compromise the skin barrier. It features a robust 2 percent Salicylic Acid load to actively dissolve keratin plugs inside the pore. To offset the astringency of the BHA, it employs an extensive 5-Ceramide matrix alongside Squalane and Centella. It utilizes SLES (Sodium Laureth Sulfate) as a significantly milder alternative to harsh SLS, providing a satisfying foam without the severe lipid destruction of traditional acne soaps safely.
