TUNEMAKERS NMF Amino Acid Undiluted Serum 20mL

Dry, thirsty skin loses the very components that keep it soft. This undiluted amino-acid solution replenishes the skin's own Natural Moisturizing Factor (NMF), sinking straight in to soften and quench from within.

【What is NMF?】The Natural Moisturizing Factor lives in the skin's outermost layer and holds on to water. About half of it is made of amino acids, with the rest PCA, lactic acid and sugars — together keeping the stratum corneum soft and hydrated.
【Eight amino acids + sodium PCA】Blended to mirror the skin's own natural balance, with betaine for extra, naturally derived moisture.
【Undiluted, straight to the skin】Not watered down — this high-concentration solution reaches dry skin directly and fills it with lasting moisture.

【The TUNEMAKERS undiluted approach】TUNEMAKERS bottles each active as a 原液 (genuine extract) — a single, undiluted ingredient you choose to match how your skin feels, then add to the routine you already use. Nothing is watered down, so it reaches your skin at full strength. In the TUNEMAKERS order it comes after your toner and before your emulsion or cream.

Suitable for: dry, dehydrated skin; sensitive skin that feels tight and rough; anyone wanting a simple, deep moisture refill.

How to use: After cleansing and toner, before emulsion or cream. Smooth an appropriate amount over the face, or mix 1–2 drops into your toner or moisturiser.

Patch-test on the inner arm before first use. If redness, itching or stinging occurs, stop use and consult a dermatologist.
