Questions, Answered

Can I layer two of these serums?

The natural pairing is Circular Hydration under a treatment serum, because its hyaluronic acid and polyglutamic acid brief is water, not treatment. Layering BioLumin-C and PowerBright together duplicates brightening work; choose the one that matches your main concern and give it the slot consistently.

BioLumin-C or PowerBright for uneven looking tone?

If the unevenness is general dullness and patchiness, BioLumin-C, with its vitamin C complex and lactic acid, is the broader tool. If the issue is defined dark spots, PowerBright is built for exactly that, with niacinamide and hexylresorcinol dosed at one pump each morning.
