Interactions
incompatible with: avoid very low-pH acid systems, use caution with strong chelators, use caution combining with highly acidic vitamin C formulas, avoid conditions that can destabilize copper-peptide complexes
Risks & Warnings
Evidence for cosmetic benefits is stronger than for major safety concerns, but high copper loads are theoretically irritating and may be poorly tolerated in very sensitive skin. Data for pregnancy-specific use are insufficient. Product performance can be affected by low pH and strong chelators.
