πŸ”¬ How It Actually Works

An AHA derived from citrus fruits. While it can exfoliate in high amounts, it is almost exclusively used in tiny amounts to adjust the pH of a product so it doesn't burn your skin.

πŸ’– Why your skin loves it

Prevents products from becoming too alkaline, ensuring safety and stability.

πŸ’‘ Pro Tip

Do not use raw lemon juice as a DIY alternativeβ€”it is highly phototoxic.

βš–οΈ Myth vs. Fact

The Myth

If it is on the label, the product is an exfoliant.

The Science

99% of the time, it is just there to balance the pH, not to peel your skin.

Low pH Good Morning Gel Cleanser
COSRX
Low pH Good Morning Gel Cleanser
Cleanser

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.

Vita-C Bright Serum
Aiken
Vita-C Bright Serum
Serum

A wildly sophisticated, multi-acid brightening and exfoliating serum. While marketed heavily as a Vitamin C serum, its primary engine is actually a powerful chemical peeling blend of Mandelic Acid, Lactic Acid, and Salicylic Acid. It rapidly digests the intracellular glue binding dead skin flakes while diving deep into the pore to dissolve oxidized sebum plugs. Buffered with Ascorbyl Glucoside to tackle hyperpigmentation safely.

Prebiotic Hydra Plus Micellar Water
Aiken
Prebiotic Hydra Plus Micellar Water
Cleanser

A highly elegant, biomimetic first-step makeup remover. By utilizing exceptionally mild emulsifiers (PEG-6 Caprylic/Capric Glycerides and Olive Oil PEG-7 Esters) instead of harsh detergents, it grabs heavy cosmetic polymers and lifts them away without disturbing native cellular lipids. The massive hydration payload of Sodium PCA, Betaine, and Hyaluronic Acid ensures the skin surface feels incredibly soft and conditioned after wiping, making it an elite choice for extremely reactive barriers that cannot tolerate traditional oil balms.
