Mechanism in Sebaceous Follicles
Cosmetic ingredients interact directly with the human follicular infundibulum. Rated at 2, Tucuma Butter exhibits mild surface slip with minimal pore-binding tendencies. Most acne-prone individuals tolerate it in standard cosmetic concentrations.
Formulation Context & The 1% Label Rule
Where Tucuma Butter appears in your product ingredient list matters significantly:
- Top 5 Inactive Ingredients: High concentration (3%–15%+). In leave-on moisturizers and sunscreens, it exerts maximum pore-clogging potential.
- Below Preservatives (<1% Rule): Listed after phenoxyethanol or ethylhexylglycerin, concentration is fractional and less likely to trigger breakouts.
- Rinse-Off Products: In facial cleansers and body washes, brief contact time minimizes follicular retention.
4-Week Patch Testing Protocol
To verify individual tolerance for a formula containing Tucuma Butter:
- Apply a small dab to a 1-inch area of the jawline once daily for four weeks.
- Keep all other skincare products and actives constant.
- Monitor weekly for closed comedones (flesh-colored bumps) or rough texture. Discontinue immediately if congestion develops.
