Mixsoon Amino Acid Powder

One ingredient, no water, no preservative system. Mixsoon's Amino Acid Powder is 100% serine, the amino acid that makes up a large share of skin's own natural moisturising factor (NMF). It exists for the customer whose toner or serum is almost right but never quite hydrating enough: instead of buying another bottle, they dose serine into the base they already use and lift its water-binding power themselves. For a Korean skincare assortment that already carries essences and ampoules, it is the booster SKU that makes the rest of the shelf work harder.

Key Benefits

• 100% Serine and nothing else — a one-ingredient formula with no fragrance, no alcohol, no colourant and no preservative to react to
• Serine is a core component of skin's natural moisturising factor, so it binds water in the upper layers for a smoother, suppler, better-cushioned surface
• Anhydrous powder format keeps the amino acid stable in the jar until the moment it is mixed
• Dose-adjustable: the same jar gives a light daily hydration boost or a heavier rescue dose
• Dissolves into toners, essences, serums, ampoules and sheet-mask essence without changing their texture
• Suits dehydrated, sensitive and barrier-compromised skin; vegan and fragrance-free

When to Use

Morning or evening, at whichever step the base product already occupies — usually toner, essence or serum, after cleansing and before moisturiser. It earns its place when hydration is the limiting factor: dry or arid climate, long hours in air conditioning, winter heating, post-flight tightness, or the flaky, rough phase that follows a course of exfoliating or retinoid actives. Daily use is fine on every skin type, including oily-dehydrated skin that wants water without extra oil.

How to Use

• Shake the container gently before opening so the powder settles loose.
• Dispense your toner, essence or serum into the palm, then tap in a small amount of powder — start with roughly a rice-grain quantity per pump.
• Mix with a fingertip until completely dissolved and no grains remain.
• Apply to the face and neck and pat until absorbed, then seal with moisturiser. Finish a morning routine with sunscreen.

Use once or twice daily. Do not apply the dry powder directly to skin.

Key Ingredients

• Serine (L-serine) — the sole ingredient at 100%. A humectant amino acid and a major part of skin's own natural moisturising factor; it holds water in the stratum corneum, helps keep the surface smooth and pliable, and is well tolerated by reactive skin.

Precautions

Keep the jar dry and tightly closed — water or steam in the container will clump an anhydrous powder. Always dissolve the powder fully before applying; undissolved grains feel gritty on skin. For external use only; avoid the eye area and rinse with water if the powder gets into the eyes. Patch test on the inner forearm before first full use, especially when mixing it into a product that already contains strong actives, and discontinue if redness, stinging or itching develops. Store away from heat and direct sunlight and keep out of reach of children.
