Mechanism in Sebaceous Follicles

Cosmetic ingredients interact directly with the human follicular infundibulum. Rated at 0 out of 5, Licorice Root Extract is bio-compatible and non-occlusive. It does not induce hyperkeratosis or promote bacterial proliferation inside the pore.

Formulation Context & The 1% Label Rule

Where Licorice Root Extract 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 Licorice Root Extract:

  1. Apply a small dab to a 1-inch area of the jawline once daily for four weeks.
  2. Keep all other skincare products and actives constant.
  3. Monitor weekly for closed comedones (flesh-colored bumps) or rough texture. Discontinue immediately if congestion develops.
