The Nati Serum is unlike anything else in the Callux range. Where most foot and hand products focus on softening or moisture, this lightweight serum-cream is built around protection — creating a daily antimicrobial environment on the skin that works quietly in the background, every single day.

Formulated for hands and feet, it is the product we reach for when a client mentions the gym, the pool, communal showers, or concerns about sweaty or odour-prone feet. It is not designed to treat any condition — it is a daily layer of defence that makes the skin a less hospitable environment for the bacteria and fungi that thrive in warm, shared spaces.

The antimicrobial action comes from two layers working together. A carefully selected blend of tea tree, lemongrass, and thyme essential oils delivers broad plant-based antimicrobial and deodorising properties, while piroctone olamine — a clinically proven broad-spectrum antimicrobial agent — reinforces that defence at a deeper level. The result is a formula that is genuinely active, not just fragrant.

The texture is the lightest in the entire Callux range. As a water-based serum-cream rather than a traditional oil-heavy moisturiser, it absorbs completely into the skin, leaving no residue, no heaviness, and no greasy finish. Lactic acid provides gentle exfoliation and moisture retention simultaneously, keeping skin smooth between appointments. For clients who have previously avoided foot creams because of how they feel, this changes everything.
