The Science
The Power of Radical Subtraction.
Most “sensitive” skincare adds soothing ingredients on top of irritating ones. We removed the irritants instead. Every Untoxicated formula starts at zero — and an ingredient only earns its way back if reactive skin truly needs it.
128+common triggers removed
11–14ingredients per formula
99%+of irritation triggers eliminated
How a formula earns its ingredients
- 1Start at zeroNo legacy ingredient list. No industry defaults. The formula begins completely empty.
- 2Screen against 128+ triggersFragrance, essential oils, dyes, harsh preservatives and common surfactant irritants are permanently excluded.
- 3Add back only what skin needsEach remaining ingredient is selected by a double board-certified allergist for one proven job.
- 4Prove it on reactive skinClinically tested on highly reactive, eczema- and allergy-prone skin — 75% preferred it over CeraVe in a blind comparison.

What makes sensitive skin react?
Most skin reactions aren't caused by “strong” skincare — they're caused by a short list of cosmetic allergens and irritants hiding inside products labelled gentle, clean, or dermatologist-tested. Fragrance compounds, essential oils, certain preservatives and harsh surfactants are behind the vast majority of cosmetic contact dermatitis.
What is the skin barrier — and why does reactive skin need fewer ingredients?
Your skin barrier is a lipid wall that keeps moisture in and irritants out. Reactive, eczema- and allergy-prone skin has a weakened wall — so every extra ingredient is another chance to provoke it. The science of barrier repair is subtraction first: remove the documented triggers, then rebuild with a short list of proven ingredients.
Which skincare ingredients should sensitive skin avoid?
Allergists consistently flag the same categories: fragrance, essential oils, dyes, lanolin, formaldehyde-releasing preservatives, methylisothiazolinone, and harsh sulfate surfactants. Untoxicated excludes all 128+ of the most documented cosmetic triggers from every formula.
