No. 143 — The Sensitive Skin Deodorant Study

The Earth‑Gentle Odor Ritual

A Quiet, Confident Kind of Protection

Some skin asks for gentleness above all else. It does not want bold botanicals, sharp essential oils, or the sting that often comes with baking soda. It wants quiet protection — something that behaves with calm consistency rather than force. No. 143 — The Sensitive Skin Deodorant Study was created for exactly that kind of skin: reactive, easily irritated, prone to redness after shaving, or simply tired of deodorants that do too much and leave discomfort behind. This Study is the gentlest member of the 140‑Series, built for people who need protection without punishment and prefer a deodorant that simply coexists with their skin.

Where No. 142 leans into bold mineral strength, No. 143 leans into restraint. Every ingredient was chosen for its ability to protect without provoking, comfort without coating, and neutralize odor without disrupting the skin’s natural rhythm. The formula is intentionally simple, intentionally quiet, and intentionally effective — a daily deodorant that feels like a soft mineral veil rather than a heavy layer. It is the kind of deodorant that disappears into the skin, leaving only comfort behind.

What It Does

No. 143 works by creating a whisper‑light mineral barrier that supports the skin’s natural processes while slowing the breakdown of sweat. Magnesium hydroxide neutralizes odor‑causing acids without the harsh alkalinity of baking soda. Zinc oxide adds a gentle cushioning effect, helping reactive skin feel calm and protected throughout the day. Triethyl citrate slows enzymatic activity, reducing the conditions that lead to odor. Glyceryl caprylate, a plant‑derived antimicrobial, offers quiet support without the intensity of essential oils or fragrance. Finally, arrowroot powder and candelilla wax work together to create a smooth, dry‑touch finish that feels breathable, clean, and comfortable.

The result is a deodorant that doesn’t fight your skin — it partners with it. No sting, no burn, no fragrance cloud. Just steady, dependable protection.

The Sensory Experience

No. 143 is designed to disappear into the skin. The glide is smooth and cushioned, thanks to shea butter and sunflower oil, but never greasy. The finish is soft‑matte and dry‑touch, allowing the underarms to feel clean rather than coated. Because the formula is completely fragrance‑free — no essential oils, no botanicals, no natural perfume — the experience is one of pure comfort. It wears quietly, effectively, and consistently, making it ideal for those who prefer their deodorant to be invisible in both scent and sensation.

Ritual

Apply to clean, dry underarms. Allow a moment for the minerals to settle into the skin’s surface. Most will find that No. 143 holds its ground through the day, but reapply as needed — especially during high‑heat or high‑activity hours. The Study is gentle enough for multiple applications without buildup or irritation.

Who It’s For

No. 143 is built for sensitive or reactive skin, post‑shave underarms, fragrance‑free lifestyles, and anyone who cannot tolerate baking soda or essential oils. It is also ideal for those who simply want a deodorant that behaves — one that offers protection without punishment, comfort without compromise, and confidence without complexity.

The Story

No. 143 was created as the soft‑spoken sibling to No. 142 — The Earth‑Mineral Deodorant Complex. Where No. 142 is bold, mineral‑forward, and designed for those who want strong protection, No. 143 is intentionally understated. It fills a necessary role in the 140‑Series: the gentlest form of daily protection, crafted for the skin that needs a quieter kind of care. Together, the Studies form a complete mineral‑based deodorant system — one for strength, one for sensitivity, and one for moisture balance — each designed to meet the body exactly where it is.
