(4) Dihydroxypropyl Arginine HCl (Amino Acid Derivative): a conditioning agent that helps the formula absorb smoothly and maintain a soft surface finish

Q: What is the difference between the OSAJI Tuning Hydrating Lotion and the OSAJI Neutral Hydrating Lotion?
A: The formula is the same — both contain the Lactate Complex, NMF components, and amino acid derivatives in identical concentrations. The only difference is fragrance: the Tuning version carries the aromatic woody scent of geranium, lavender, myrrh, hinoki, and yuzu. The Neutral version is completely fragrance-free. If scent sensitivity is a concern, the Neutral line is the safer choice.
Q: What does the OSAJI Tuning Hydrating Lotion scent smell like?
A: It's an aromatic woody fragrance — soft and grounding rather than floral or citrus-forward. Geranium and lavender open the scent with a gentle herbal quality. Myrrh and hinoki cypress bring warmth and depth in the middle. A bright note of yuzu lifts the finish slightly. Several reviewers note it's stronger than expected on first contact but settles quickly to something quieter and more subtle on the skin.
Q: Is the OSAJI Tuning Hydrating Lotion suitable for oily or combination skin?
A: Yes — the formula is designed to be high-moisture without any heaviness or residue. The water-first base and NMF-focused ingredients mean it absorbs cleanly and doesn't sit on the skin's surface. OSAJI specifically lists fluctuating oily or combination skin prone to shininess as one of the target conditions for this lotion.
Q: How much should I use per application of the OSAJI Tuning Hydrating Lotion?
A: OSAJI recommends a 500-yen coin sized amount (roughly a generous palmful) per application, pressed into the skin rather than patted or swept. For noticeably dry areas, layering a second application is recommended.
Q: Can the OSAJI Tuning Hydrating Lotion be used as a sheet mask soaker?
A: Yes — the watery, low-viscosity texture makes it well-suited for use with a cotton pad mask or hydrating sheet. OSAJI also offers their own Tuning Moisture Sheet Mask as part of the same line for a more intensive version of this step.
