Chlorophyllin-Copper Complex

Chlorophyllin-copper complex is a water-soluble chlorophyll derivative used mainly as a colorant/antioxidant and is typically included at low concentrations (often well under 1%), where it is generally well tolerated in patch-testing and consumer use. However, as a botanical-derived pigment complex it can still trigger irritation or allergy in a small subset of highly reactive or eczema-prone patients (and can be more stinging on compromised barriers), so I rate it as gentle but not “exceptionally gentle.” Safety Notes: In commercial skincare, chlorophyllin-copper complex is most often used as a colorant/marketing active in low-dose deodorizing/“anti-odor” or soothing formulas, commonly appearing in leave-on products at trace levels around 0.0001–0.01% (especially when supplied as a dilute solution or carried in a blend). Higher-strength consumer-available products (notably deodorizing masks, acne/clarifying gels, and some specialty “chlorophyll” serums) can reach roughly 0.1–0.5% active, with the upper end constrained by color intensity, staining risk, odor, and stability/compatibility in the finished base; rinse-off products typically sit toward the lower-mid end because short contact time reduces the need for very high loading.
